Jami` at-Tirmidhi 391
There is a narrated with another chain that Abu Hurairah and ['Abdullah bin] As-Sa'id Al-Qari' would perform the prostrations of As-Sahw before the Taslim.

Abu 'Eisa said:

The Hadith of Ibn Buhainah is a Hasan [Sahih] Hadith, and this is acted upon according to some of the people of knowledge. It is the opinion of Ash-Shafi'i, he held the view that all prostrations for As-Sahw were to be performed before the Salam, saying: "This one abrogates the other Ahadith" and he mentioned that the last action of the Prophet (saws) was according to this.

Ahmad and Ishaq said: "When a man stands up after two Rak'ah, then he performs the prostrations for As-Sahw before the Salam according to the Hadith of Ibn Buhainah."

'Abdullah bin Buhainah is 'Abdullah bin Malik [so he is] Ibn Buhainah (because) Malik is his father and Buhainah is his mother.

I was informed of this by Ishaq bin Mansur from 'Ali [bin 'Abdullah] bin Al-Madini.

Abu 'Eisa said: The people of knowledge differ over when a man is to perform the prostrations of As-Sahw, is it before the Salam or after it. Some of them thought that her performs them after the Salam. This is the view of Sufyan Ath-Thawri and the people of Al-Kufah. Some of them said he performs them before the Salam. This is the view of most of the Fuqaha among the people of Al-Madinah, like Yahya bin Sa'eed, Rabi'ah, and others. This is also the saying of Ash-Shafi'i.

Some of them said when he adds to the Salat, then it is after the Salam, and when he leaves something out, then before the Salam. This is the view of Malik bin Anas.

Ahmad said: "Whatever is reported from the Prophet (saws) about the prostrations from As-Sahw then it is acted upon in either case." He saw that when one stands after Rak'ah then according to the Hadith of Ibn Buhainah, he is to perform the prostrations before the Salam. When he prays five for Zuhr, then performs the prostrations after the Salam, and if he says Salam after two Rak'ahs of Zuhr or 'Asr then he performs the prostrations after the Salam. All of them are to be acted upon depending upon the case, and in the cases where nothing is reported from the Prophet (saws), then two prostrations are performed for As-Sahw before the Salam.

Ishaq said the same as Ahmad about all of this, with the exception that he said that for every case of As-Sahw that is not mentioned from the Prophet (saws), then if it is an addition to the Salat, then prostrations are performed after the Salam, and if it is something that was left out, then the prostrations are performed before the Salam.

Narrated Abu Huraira:

Allah's Apostle said, "When the Adhan for the prayer is pronounced, then Satan takes to his heels passing wind so that he may not hear the Adhan and when the Mu'adh-dhin finishes, he comes back; and when the Iqama is pronounced he again takes to his heels and when it is finished, he again comes back and continues reminding the praying person of things that he used not to remember when not in prayer till he forgets how much he has prayed." Abu Salama bin `Abdur-Rahman said, "If anyone of you has such a thing (forgetting the number of rak`at he has prayed) he should perform two prostrations of Sahu (i.e. forgetfulness) while sitting." Abu Salama narrates this from Abu Huraira.

The Messenger of Allah (PBUH) said, "Allah, the Exalted, has laid down certain duties which you should not neglect, and has put certain limits which you should not transgress, and has kept silent about other matters out of mercy for you and not out of forgetfulness, so do not seek to investigate them."

Narrated `Abdullah:

The Prophet prayed (and the sub-narrator Ibrahim said, "I do not know whether he prayed more or less than usual"), and when he had finished the prayers he was asked, "O Allah's Apostle! Has there been any change in the prayers?" He said, "What is it?' The people said, "You have prayed so much and so much." So the Prophet bent his legs, faced the Qibla and performed two prostration's (of Sahu) and finished his prayers with Taslim (by turning his face to right and left saying: 'As-Salamu `Alaikum- Warahmat-ullah'). When he turned his face to us he said, "If there had been anything changed in the prayer, surely I would have informed you but I am a human being like you and liable to forget like you. So if I forget remind me and if anyone of you is doubtful about his prayer, he should follow what he thinks to be correct and complete his prayer accordingly and finish it and do two prostrations (of Sahu).

Narrated Abu Huraira:

The Prophet led us in the Zuhr prayer, offering only two rak`at and then (finished it) with Taslim, and went to a piece of wood in front of the mosque and put his hand over it. Abu Bakr and `Umar were also present among the people on that day but dared not talk to him (about his unfinished prayer). And the hasty people went away, wondering. "Has the prayer been shortened" Among the people there was a man whom the Prophet used to call Dhul-Yadain (the longarmed). He said, "O Allah's Prophet! Have you forgotten or has the prayer been shortened?" The Prophet said, "Neither have I forgotten, nor has it been shortened." They (the people) said, "Surely, you have forgotten, O Allah's Apostle!" The Prophet said, Dhul-Yadain has told the truth." So the Prophet got up and offered other two rak`at and finished his prayer with Taslim. Then he said Takbir, performed a prostration of ordinary duration or longer, then he raised his head and said Takbir and performed another prostration of ordinary duration or longer and then raised his head and said Takbir (i.e. he performed the two prostrations of Sahu, i.e., forgetfulness).

Sahih al-Bukhari 6670

Narrated `Abdullah bin Buhaina:

Once Allah's Apostle led us in prayer, and after finishing the first two rak`at, got up (instead of sitting for at-Tahiyyat) and then carried on with the prayer. When he had finished his prayer, the people were waiting for him to say Taslim, but before saying Tasiim, he said Takbir and prostrated; then he raised his head, and saying Takbir, he prostrated (SAHU) and then raised his head and finished his prayer with Taslim.

Sunan Ibn Majah 1213
It was narrated from Ibn ‘Umar that the Messenger of Allah (saw) forgot and said the Taslim after two Rak’ah. A man who was called Dhul-Yadain said to him:
‘O Messenger of Allah, has the prayer been shortened or did you forget?’ He said: ‘It has not been shortened and I did not forget.’ He said: ‘But you prayed two Rak’ah.’ He said: ‘Is what Dhul-Yadain says true?’ They said: ‘Yes.’ So he went forward and performed two Rak’ah and said the Salam, then he prostrated twice for prostrations of forgetfulness.

On the authority of Abu Tha’labah al-Kushanee — Jurthoom bin Nashir (may Allah be pleased with him) — that the Messenger of Allah (peace and blessings of Allah be upon him) said:

Verily Allah ta’ala has laid down religious obligations (fara’id), so do not neglect them; and He has set limits, so do not overstep them; and He has forbidden some things, so do not violate them; and He has remained silent about some things, out of compassion for you, not forgetfulnessso do not seek after them.

Narrated Abu Huraira:

Allah's Apostle finished his prayer after offerings two rak`at only. Dhul-Yaddain asked him whether the prayer had been reduced, or you had forgotten?" The Prophet said, "Is Dhul-Yaddain speaking the truth?" The people said, "Yes." Then Allah's Apostle stood up and performed another two rak`at and then finished prayer with Taslim, and then said the Takbir and performed a prostration similar to or longer than his ordinary prostrations; then he raised his head, said Takbir and prostrated and then raised his head (Sahu prostrations).

Narrated AbuHurayrah:

When the Prophet (saws) finished two rak'ahs of an obligatory prayer, a man asked him: Messenger of Allah, has the prayer been shortened, or have you forgotten? he replied: I did not do all that. The people said: Messenger of Allah, you did that. Therefore, he offered another two rak'ahs or prayer and did not make two prostrations due to forgetfulness.

Abu Dawud said: This tradition has also been narrated by Dawud al-Hussain from Abu Sufyan, freed slave of Ibn Abi Ahmad on the authority of Abu Hurairah from the Prophet (saws). This version goes: He then made two prostrations while he was sitting after the salutation.

The Prophet led us in the `Asr or the Zuhr prayer and finished it with Taslim. Dhul-Yadain said to him, "O Allah's Apostle! Has the prayer been reduced?" The Prophet asked his companions in the affirmative. So Allah's Apostle I offered two more rak`at and then performed two prostrations (of Sahu). Sa`d said, "I saw that 'Urwa bin Az-Zubair had offered two rak`at in the Maghrib prayer and finished it with Taslim. He then talked (and when he was informed about it) he completed the rest of his prayer and performed two prostrations, and said, 'The Prophet prayed like this.' "

Narrated Ubai bin Ka`b:

Allah's Apostle said, "Moses the Apostle of Allah," and then he narrated the whole story about him. Al-Khadir said to Moses, "Did not I tell you that you can have no patience with me." (18.72). Moses then violated the agreement for the first time because of forgetfulness, then Moses promised that if he asked Al-Khadir about anything, the latter would have the right to desert him. Moses abided by that condition and on the third occasion he intentionally asked Al-Khadir and caused that condition to be applied. The three occasions referred to above are referred to by the following Verses: "Call me not to account for forgetting And be not hard upon me." (18.73) "Then they met a boy and Khadir killed him." (18.74) "Then they proceeded and found a wall which was on the verge of falling and Khadir set it up straight." (18.77)

If anyone of you does not remember whether he has offered three or four rak`at then he should perform two prostrations of Sahu while sitting.

Al-Mughirah b. Shu’bah said :

The Messenger of Allah (saws) lagged behind (in a journey). He then narrated this story saying : Then we came to people. ‘Abd al-Rahman was leading them in the dawn prayer. When he perceived the presence of the Prophet (saws), he intended to retire. The Prophet (saws) asked him to continue and I and the Prophet (saws)offered one rak’ah of prayer behind him. When he had pronounced the salutation, the Prophet(saws) got up and offered the rak’ah which had been finished before, and he made no addition to it.

Abu Dawud said: Abu Sa’id al-Khudri, Ibn al-Zubair and Ibn ‘Umar hold the opinion that whoever gets an odd number of the rak’ahs of prayer, he should perform two prostrations on account of forgetfulness.

Allah's Messenger (may peace be upon him) stopped while riding his camel and the people began to ask him. One of the inquirers said: Messenger of Allah, I did not know that pebbles should be thrown before sacrificing the animal, and by mistake I sacrificed the animal before throwing pebbles, whereupon Allah's Messenger (may peace be upon him) said: (Now) throw pebbles and there is no harm in it. Then another (person) came saying: I did not know that the animal was to be sacrificed before shaving, but I got myself shaved before sacrificing the animal, whereupon he (the Holy Prophet) said: Sacrifice the animal (now) and there is no harm in it. He (the narrator) said: I did not hear that anything was asked on that day (shout a matter) which a person forgot and could not observe the sequence or anything like it either due to forgetfulness or ignorance, but Allah's Messenger (may peace be upon him) said (about that): Do it; there is no harm in it.

Yahya related to me from Malik thatYahya ibn Said used to say, "Even if someone manages to pray before the time of the prayer has passed, the time that has passed him by is more important, or better, than his family and wealth."

Yahya said that Malik said, "If the time for a prayer comes and a traveller delays a prayer through neglect or forgetfulness until he reaches his family, he should do that prayer in full if he arrives within the time. But if he arrives when the time has past, he should do the travelling prayer. That way he only repays what he owes."

Malik said, "This is what I have found the people and men of knowledge doing in our community." Malik explained that shafaq was the redness in the sky after the sun had set, and said, "When the redness has gone then the isha prayer is due and you have left the time of maghrib."

Narrated Al-Mughirah ibn Shu'bah:

Ziyad ibn Ilaqah said: Al-Mughirah ibn Shu'bah led us in prayer and he stood up at the end of two rak'ahs. We said: Glory be to Allah; he also said: Glory be to Allah, and he proceeded. When he finished the prayer and gave the salutation, he made two prostrations of forgetfulness. When he turned (to us) he said: I saw the Messenger of Allah (saws) doing so as I did.

Abu Dawud said: Ibn Abi Laila narrated this tradition in a similar manner from al-Shaibi from al-Mughirah b. Shu'bah. Abu 'Umais narrated it from Thabit b. 'Ubaid saying: "Al-Mughirah b. Shu'bah led us in prayer, like the tradition reported by Ziyad b. 'Illaqah.

Abu Dawud said: Abu 'Umais is the brother of al-Mas'udi. And Sa'd b. Abi Waqqas did the same as done by al-Mughirah, 'Imran b. Husain, Dahhak b. Qais and Mu'awiyah b. Abi Sufyan. Ibn 'Abbas and 'Umar b. 'Abd al-'Aziz issued legel verdict to the same effect.

Abu Dawud said: This applies to a person who stands up at the end of two rak'ahs and males prostration after giving the salutation.

Narrated Abu Huraira:

The Prophet offered one of the evening prayers (the sub-narrator Muhammad said, "I think that it was most probably the `Asr prayer") and he finished it after offering two rak`at only. He then stood near a price of wood in front of the Mosque and put his hand over it. Abu Bakr and `Umar were amongst those who were present, but they dared not talk to him about that (because of excessive respect for him), and those who were in a hurry went out. They said, "Has the prayer been reduced?" A man who was called Dhul-Yadain by the Prophet said (to the Prophet), "Has the prayer been reduced or have you forgotten?" He said, "Neither have I forgotten, nor has the prayer been reduced." He said, "Certainly you have forgotten." So the Prophet offered two more rak`at and performed Taslim and then said Takbir and performed a prostration of Sahu like his ordinary prostration or a bit longer and then raised his head and said Takbir and then put his head down and performed a prostration like his ordinary prostration or a bit longer, and then raised his head and said Takbir.

Sunan Abi Dawud 1008
Abu Hurairah said:
The Messenger of Allah (may peace be upon him) led us in one of the evening (‘Asha) prayers, noon or afternoon. He led us in two Rak’ahs and gave the salutation. He then got up going towards a piece of wood which was placed in the front part of the mosque. He placed his hands upon it, one on the other, looking from his face as if he were angry. The people came out hastily saying: the prayer has been shortened. Abu Bakr and ‘Umar were among the people, but they were too afraid to speak to him. A man whom the Messenger of Allah (may peace be upon him) would call “ the possessor of arms” (Dhu al-Yadain) stood up (asking him): Have you forgotten. The Messenger of Allah, or has the prayer been shortened? He said: I have neither forgotten nor has it been shortened. He said : Messenger of Allah , you have forgotten. The Messenger of Allah (may peace be upon him) turned towards the people and asked : did the possessor of arms speak the truth? They made a sign , that is, yes. The Messenger of Allah (may peace be upon him) returned to his place and prayed the remaining two Rak’ahs, then gave the salutation; he then uttered the takbir and prostrated himself as usual or prolonged. He then raised his head and uttered the takbir; then he uttered the takbir and made prostration as usual or made longer (prostration). Then he raised his head his and uttered the takbir (Allah is most great). The narrator Muhammad was asked : Did he give the salutation (while prostrating) dueto forgetfulness? He said : I do not remember it from Abu Hurairah. But we Are sure that ‘Imran b. Husain (in his version) said; he then gave the salutation.

Yahya related to me from Malik that Ata ibn Abdullah al-Khurasani said that an old man from Suq al-Buram in Kufa had related to him that Kab ibn Ujra said, "The Messenger of Allah, may Allah bless him and grant him peace, came to me while I was blowing under a cooking pot belonging to my companions and my head and beard were full of lice. He took my forehead and said, 'Shave your hair and fast three days or feed six poor people.' The Messenger of Allah, may Allah bless him and grant him peace, was aware that I did not have anything with me to sacrifice.'"

Malik said, concerning paying compensation (fidya) for the relief of physical discomfort, "The custom concerning it is that no one pays compensation until he has done something which makes it obligatory to pay compensation just as making amends (kaffara) is only done when it has become obligatory for the one who owes it. The person can pay the compensation wherever he wishes, regardless of whether he has to sacrifice an animal or fast or give sadaqa -- in Makka or in any other town."

Malik said, "It is not correct for a person in ihram to pluck out any of his hair or to shave it or cut it until he has left ihram, unless he is suffering from an ailment of the head, in which case he owes the compensation Allah the Exalted has ordered. It is not correct for a person in ihram to cut his nails, or to kill his lice, or to remove them from his head or from his skin or his garment to the ground. If a person in ihram removes lice from his skin or his garment, he must give away the quantity of food that he can scoop up with both hands. "

Malik said,"Anyone who, while in ihram, plucks out hairs from his nose or armpit or rubs his body with a depilatory agent or shaves the hair from around a head wound out of necessity or shaves his neck for the place of the cupping glasses, regardless of whether it is in forgetfulness or in ignorance, owes compensation in all these instances, and he must not shave the place of the cupping glasses. Someone, who, out of ignorance, shaves his head before he stones the jamra. must also pay compensation."

Yahya said that he heard Malik say, "Someone who eats or drinks out of neglect or forgetfulness during a voluntary fast does not have to repeat his fast, but he should continue fasting for the rest of the day in which he eats or drinks while voluntarily fasting, and not stop fasting. Someone to whom something unexpected happens which causes him to break his fast while he is fasting voluntarily does not have to repeat his fast if he has broken it for a reason, and not simply because he decided to break his fast. Just as I do not think that someone has to repeat a voluntary prayer if he has had to stop it because of some discharge which he could prevent and which meant that he had to repeat his wudu."

Malik said, "Once a man has begun doing any of the right actions (al-amal as-saliha) such as the prayer, the fast and the hajj, or similar right actions of a voluntary nature, he should not stop until he has completed it according to what the sunna for that action is. If he says the takbir he should not stop until he has prayed two rakas. If he is fasting he should not break his fast until he has completed that day's fast. If he goes into ihram he should not return until he has completed his hajj, and if he begins doing tawaf he should not stop doing so until he has gone around the Kaba seven times. He should not stop doing any of these actions once he has started them until he has completed them, except if something happens such as illness or some other matter by which a man is excused. This is because Allah, the Blessed and Exalted, says in His Book, 'And eat and drink until the white thread becomes clear to you from the black thread of dawn, (and) then complete the fast until night-time,' (Sura 2 ayat 187), and so he must complete his fast as Allah has said. Allah, the Exalted, (also) says, 'And complete the hajj and the umra for Allah,' and so if a man were to go into ihram for a voluntary hajj having done his one obligatory hajj (on a previous occasion), he could not then stop doing his hajj having once begun it and leave ihram while in the middle of his hajj. Anyone that begins a voluntary act must complete it once he has begun doing it, just as an obligatory act must be completed . This is the best of what I have heard."

Narrated Zaid bin Thabit Al-Ansari:

who was one of those who used to write the Divine Revelation: Abu Bakr sent for me after the (heavy) casualties among the warriors (of the battle) of Yamama (where a great number of Qurra' were killed). `Umar was present with Abu Bakr who said, `Umar has come to me and said, The people have suffered heavy casualties on the day of (the battle of) Yamama, and I am afraid that there will be more casualties among the Qurra' (those who know the Qur'an by heart) at other battle-fields, whereby a large part of the Qur'an may be lost, unless you collect it. And I am of the opinion that you should collect the Qur'an." Abu Bakr added, "I said to `Umar, 'How can I do something which Allah's Apostle has not done?' `Umar said (to me), 'By Allah, it is (really) a good thing.' So `Umar kept on pressing, trying to persuade me to accept his proposal, till Allah opened my bosom for it and I had the same opinion as `Umar." (Zaid bin Thabit added:) `Umar was sitting with him (Abu Bakr) and was not speaking. me). "You are a wise young man and we do not suspect you (of telling lies or of forgetfulness): and you used to write the Divine Inspiration for Allah's Apostle. Therefore, look for the Qur'an and collect it (in one manuscript). " By Allah, if he (Abu Bakr) had ordered me to shift one of the mountains (from its place) it would not have been harder for me than what he had ordered me concerning the collection of the Qur'an. I said to both of them, "How dare you do a thing which the Prophet has not done?" Abu Bakr said, "By Allah, it is (really) a good thing. So I kept on arguing with him about it till Allah opened my bosom for that which He had opened the bosoms of Abu Bakr and `Umar. So I started locating Qur'anic material and collecting it from parchments, scapula, leaf-stalks of date palms and from the memories of men (who knew it by heart). I found with Khuza`ima two Verses of Surat-at-Tauba which I had not found with anybody else, (and they were):-- "Verily there has come to you an Apostle (Muhammad) from amongst yourselves. It grieves him that you should receive any injury or difficulty He (Muhammad) is ardently anxious over you (to be rightly guided)" (9.128) The manuscript on which the Qur'an was collected, remained with Abu Bakr till Allah took him unto Him, and then with `Umar till Allah took him unto Him, and finally it remained with Hafsa, `Umar's daughter.

‘Umar b. al-Khattab said:
I asked the Prophet’s permission to perform an ‘umra and he gave me permission, saying, “Include me in your supplication, little brother, and do not forget me.” Then he said a word to me for which I would not be willing to take the world in exchange. Abu Dawud and Tirmidhi transmitted it, Tirmidhi’s version ending with “do not forget me.”

حَدَّثَنَا مُحَمَّدُ بْنُ عَوْفٍ، حَدَّثَنَا عُثْمَانُ بْنُ سَعِيدٍ، عَنْ أَبِي غَسَّانَ، مُحَمَّدِ بْنِ مُطَرِّفٍ الْمَدَنِيِّ عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ نَامَ عَنْ وِتْرِهِ أَوْ نَسِيَهُ فَلْيُصَلِّهِ إِذَا ذَكَرَهُ ‏"‏ ‏.‏

Bismillāh. And if you forget then when you remember, say: Bismillāhi fī awwalihi wa ākhirih. When anyone of you begins eating, say: With the Name of Allah. And if you forget then, when you remember, say: With the Name of Allah, in the beginning, and in the end. Reference: Abu Dawud 3/347, At-Tirmidhi 4/288. See Al- Albani's Sahih At-Tirmidhi 2/167.

"What an evil servant is the one who fancies himself and becomes vain forgetting the Most Great, the Most High. What an evil servant is the one who forces and behaves hostility, forgetting the Compeller, the Most High.

Sa'id b. Jubair reported:

I said to Ibn Abbas that Nauf al-Bikali was of the opinion that Moses (peace be upon him), the Apostle of Bani Isra'il, was not the same who accompanied Khadir, whereupon he said: The enemy of Allah tells a lie. I heard Ubayy b. Ka'b say: Moses (peace be upon him) stood up to give sermon to the people of Isra'il. He was asked as to who amongst the people has the best knowledge, whereupon he said: I have the best knowledge. Thereupon Allah was annoyed with him that he did not attribute (the best knowledge) to Him. He revealed to him: A servant amongst My servants is at the junction of two rivers who has more knowledge than yours. Moses said: How can I meet him? It was said to him: Carry a fish in the large basket and the place where you find it missing there you will find him. Thereupon Moses proceeded forth along with a young man (Yusha'). Joshua b. Nun and Moses (peace be upon him) put the fish in the basket and there went along with him the young man (Yusha') until they came to a certain rock and Moses and his companion went to sleep and the fish stirred in that basket and fell into the ocean and Allah stopped the current of water like a vault until the way was made for the fish. Moses and his young companion were astonished and they walked for the rest of the day and the night and the friend of Moses forgot to inform him of this incident. When it was morning, Moses (peace be upon him) said to the young man: Bring for us the breakfast for we are dead tired because of this journey, and they did not feel exhausted until they had passed that place where they had been commanded (to stay). He said: Don't you know that when we reached the Sakhra (rock) I forgot the fish and nothing made me forget it but Satan that I could not remember it? How strange is it that the fish found a way in the river? Moses said: That was what we had been aiming at. Then both of them retraced their steps until they reached Sakhra; there they saw a man covered with a cloth. Moses greeted him. Khadir said to him: Where is as-Salam in our country.? He said: I am Moses, whereupon he (Khadir) said: You mean the Moses of Bani Isra'il? He said: Yes. He (Khadir) said: You have a knowledge out of the knowledge of Allah which in fact Allah imparted to you and about that I know nothing and I have knowledge out of Allah's knowledge which He imparted to me and about that you do not know. Moses (peace be upon him) said to him: May I follow you so that you may teach me that with which you have been taught righteousness. He said: You will not be able to bear with me; how you will be able to bear that about which you do not know? Moses said: Thou wilt find me patient, nor shalt I disobey you in aught. Khadir said to him: If you were to follow me, then do not ask me about anything until I myself speak to you about it. He said: Yes. So Khadir and Moses set forth on the bank of the river that there came before them a boat. Both of them talked to them (the owners of the boat) so that they might carry both of them. They had recognised Khadir and they carried them free. Khadir thereupon took hold of a plank in the boat and broke it away. Moses said: These people have carried us without any charge and you attempt to break their boat so that the people sailing in the boat may drown. This is (something) grievous that you have done. He said: Did I not say that you would not bear with me? He said: Blame me not for what I forgot and be not hard upon what I did. Then both of them got down from the boat and began to walk along the coastline that they saw a boy who had been playing with other boys. Khadir pulled up his head and killed him. Moses said: Have you killed an innocent person who is in no way guilty of slaying another? You have done something horrible. Thereupon he said: Did I not say to you that you will not be able to bear with me? He (Moses) said: This (act) is more grievous than the first one. He (Moses) further said. If I ask you about anything after this, keep not company with me, then you would no doubt find (a plausible) excuse for this. Then they both walked on until they reached the inhabitants of a village. They asked its inhabitants for food but they refused to entertain them as their guests. They found in it a wall which had been bent on one side and was about to fall. Khadir set it right with his own hand. Moses, said to him: It is the people to whom we came but they showed us no hospitality and they did not serve us food. If you wish you can get wages for it. He (Khadir) said: This is the parting of ways between me and you. Now I wish to reveal to you the significance of that for which you could not bear with me. Allah's Messenger (may peace be upon him) said. May Allah have mercy upon Moses! I wish if Moses could show patience and a (fuller) story of both of them could have been told. Allah's Messenger (may peace be upon him) said that the first thing which Moses said was out of forgetfulness. Then there came a sparrow until it perched on the wall of the boat and took water from the ocean. Thereupon, Khadir said: My knowledge and your knowledge in comparison with the knowledge of Allah is even less than the water taken by the sparrow in its beak in comparison to the water of the ocean, and Sa'id b. Jubair used to recite (verses 79 and 80 of Sura Kahf) in this way: There was before them a king who used to seize every boat by force which was in order, the boy was an unbeliever.

Narrated Ibn Juraij:

Ya`la bin Muslim and `Amr bin Dinar and some others narrated the narration of Sa`id bin Jubair. Narrated Sa`id: While we were at the house of Ibn `Abbas, Ibn `Abbas said, "Ask me (any question)" I said, "O Abu `Abbas! May Allah let me be sacrificed for you ! There is a man at Kufa who is a storyteller called Nauf; who claims that he (Al-Khadir's companion) is not Moses of Bani Israel." As for `Amr, he said to me, "Ibn `Abbas said, "(Nauf) the enemy of Allah told a lie." But Ya`la said to me, "Ibn `Abbas said, Ubai bin Ka`b said, Allah's Apostle said, 'Once Moses, Allah's Apostle, preached to the people till their eyes shed tears and their hearts became tender, whereupon he finished his sermon. Then a man came to Moses and asked, 'O Allah's Apostle! Is there anyone on the earth who is more learned than you?' Moses replied, 'No.' So Allah admonished him (Moses), for he did not ascribe all knowledge to Allah. It was said, (on behalf of Allah), 'Yes, (there is a slave of ours who knows more than you ).' Moses said, 'O my Lord! Where is he?' Allah said, 'At the junction of the two seas.' Moses said, 'O my Lord ! Tell I me of a sign whereby I will recognize the place.' " `Amr said to me, Allah said, "That place will be where the fish will leave you." Ya`la said to me, "Allah said (to Moses), 'Take a dead fish (and your goal will be) the place where it will become alive.' " So Moses took a fish and put it in a basket and said to his boy-servant "I don't want to trouble you, except that you should inform me as soon as this fish leaves you." He said (to Moses)." You have not demanded too much." And that is as mentioned by Allah: 'And (remember) when Moses said to his attendant .... ' (18.60) Yusha` bin Noon. (Sa`id did not state that). The Prophet said, "While the attendant was in the shade of the rock at a wet place, the fish slipped out (alive) while Moses was sleeping. His attend an said (to himself), "I will not wake him, but when he woke up, he forgot to tell him The fish slipped out and entered the sea. Allah stopped the flow of the sea. where the fish was, so that its trace looked as if it was made on a rock. `Amr forming a hole with his two thumbs an index fingers, said to me, "Like this, as in its trace was made on a rock." Moses said "We have suffered much fatigue on this journey of ours." (This was not narrated by Sa`id). Then they returned back and found Al-Khadir. `Uthman bin Abi Sulaiman said to me, (they found him) on a green carpet in the middle of the sea. Al-Khadir was covered with his garment with one end under his feet and the other end under his head. When Moses greeted, he uncovered his face and said astonishingly, 'Is there such a greeting in my land? Who are you?' Moses said, 'I am Moses.' Al- Khadir said, 'Are you the Moses of Bani Israel?' Moses said, 'Yes.' Al-Khadir said, "What do you want?' Moses said, ' I came to you so that you may teach me of the truth which you were taught.' Al- Khadir said, 'Is it not sufficient for you that the Torah is in your hands and the Divine Inspiration comes to you, O Moses? Verily, I have a knowledge that you ought not learn, and you have a knowledge which I ought not learn.' At that time a bird took with its beak (some water) from the sea: Al-Khadir then said, 'By Allah, my knowledge and your knowledge besides Allah's Knowledge is like what this bird has taken with its beak from the sea.' Until, when they went on board the boat (18.71). They found a small boat which used to carry the people from this sea-side to the other sea-side. The crew recognized Al-Khadir and said, 'The pious slave of Allah.' (We said to Sa`id "Was that Khadir?" He said, "Yes.") The boat men said, 'We will not get him on board with fare.' Al-Khadir scuttled the boat and then plugged the hole with a piece of wood. Moses said, 'Have you scuttled it in order to drown these people surely, you have done a dreadful thing. (18.71) (Mujahid said. "Moses said so protestingly.") Al-Khadir said, didn't I say that you can have no patience with me?' (18.72) The first inquiry of Moses was done because of forgetfulness, the second caused him to be bound with a stipulation, and the third was done intentionally. Moses said, 'Call me not to account for what I forgot and be not hard upon me for my affair (with you).' (18.73) (Then) they found a boy and Al-Khadir killed him. Ya`la- said: Sa`id said 'They found boys playing and Al-Khadir got hold of a handsome infidel boy laid him down and then slew him with knife. Moses said, 'Have you killed a innocent soul who has killed nobody' (18.74) Then they proceeded and found a wall which was on the point of falling down, and Al-Khadir set it up straight. Sa`id moved his hand thus and said 'Al-Khadir raised his hand and the wall became straight. Ya`la said, 'I think Sa`id said, 'Al-Khadir touched the wall with his hand and it became straight (Moses said to Al-Khadir), 'If you had wished, you could have taken wages for it.' Sa`id said, 'Wages that we might had eaten.' And there was a king in furor (ahead) of them" (18.79) And there was in front of them. Ibn `Abbas recited: 'In front of them (was) a king.' It is said on the authority of somebody other than Sa`id that the king was Hudad bin Budad. They say that the boy was called Haisur. 'A king who seized every ship by force. (18.79) So I wished that if that boat passed by him, he would leave it because of its defect and when they have passed they would repair it and get benefit from it. Some people said that they closed that hole with a bottle, and some said with tar. 'His parents were believers, and he (the boy) was a non-believer and we (Khadir) feared lest he would oppress them by obstinate rebellion and disbelief.' (18.80) (i.e. that their love for him would urge them to follow him in his religion, 'so we (Khadir) desired that their Lord should change him for them for one better in righteousness and near to mercy' (18:81). This was in reply to Moses' saying: Have you killed an innocent soul.'? (18.74). 'Near to mercy" means they will be more merciful to him than they were to the former whom Khadir had killed. Other than Sa`id, said that they were compensated with a girl. Dawud bin Abi `Asim said on the authority of more than one that this next child was a girl.

He asked, and we told him, so he turned to face the Qiblah and prostrated twice, then he said the Salam. Then he turned to face us and said: ‘If any new command has been revealed concerning the prayer, I would certainly have told you. But I am only human and I forget and you forget. If I forget, then remind me. And if anyone of you is uncertain about the prayer, let him do what is closest to what is correct, then complete the prayer, say the Salam and prostrate twice.”

Abu Qatada reported God’s Messenger as saying, “There is no remissness in sleep, it is only when one is awake that there is remissness; so when any of you forgets a stated prayer or oversleeps, he should observe it when he remembers it, for God has said, ‘And observe the prayer for remembrance of Me’” (Al-Qur’an, 20:14). Muslim transmitted it.

حَدَّثَنَا قُتَيْبَةُ، وَبِشْرُ بْنُ مُعَاذٍ، قَالاَ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ نَسِيَ صَلاَةً فَلْيُصَلِّهَا إِذَا ذَكَرَهَا ‏"‏ ‏.‏ وَفِي الْبَابِ عَنْ سَمُرَةَ وَأَبِي قَتَادَةَ ‏.‏ قَالَ أَبُو عِيسَى حَدِيثُ أَنَسٍ حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏ وَيُرْوَى عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ أَنَّهُ قَالَ فِي الرَّجُلِ يَنْسَى الصَّلاَةَ قَالَ يُصَلِّيهَا مَتَى مَا ذَكَرَهَا فِي وَقْتٍ أَوْ فِي غَيْرِ وَقْتٍ ‏.‏ وَهُوَ قَوْلُ الشَّافِعِيِّ وَأَحْمَدَ بْنِ حَنْبَلٍ وَإِسْحَاقَ ‏.‏ وَيُرْوَى عَنْ أَبِي بَكْرَةَ أَنَّهُ نَامَ عَنْ صَلاَةِ الْعَصْرِ فَاسْتَيْقَظَ عِنْدَ غُرُوبِ الشَّمْسِ فَلَمْ يُصَلِّ حَتَّى غَرَبَتِ الشَّمْسُ ‏.‏ وَقَدْ ذَهَبَ قَوْمٌ مِنْ أَهْلِ الْكُوفَةِ إِلَى هَذَا وَأَمَّا أَصْحَابُنَا فَذَهَبُوا إِلَى قَوْلِ عَلِيِّ بْنِ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ ‏.‏

Yahya related to me from Malik from Ayyub ibn Abi Tamima as- Sakhtayani from Said ibn Jubayr that Abdullah ibn Abbas said, "If someone forgets anything of the rituals or omits them intentionally, he must slaughter an animal." Ayyub added "I do not know if he said 'Omits' or 'forgets'."

Malik said, "If it is a hady that has to be slaughtered it may only be done in Makka, but if it is a sacrifice, it may be slaughtered wherever the one who owes the sacrifice prefers."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ أَيُّوبَ بْنِ أَبِي تَمِيمَةَ السَّخْتِيَانِيِّ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، قَالَ مَنْ نَسِيَ مِنْ نُسُكِهِ شَيْئًا أَوْ تَرَكَهُ فَلْيُهْرِقْ دَمًا ‏.‏ قَالَ أَيُّوبُ لاَ أَدْرِي قَالَ تَرَكَ أَوْ نَسِيَ ‏.‏ قَالَ مَالِكٌ مَا كَانَ مِنْ ذَلِكَ هَدْيًا فَلاَ يَكُونُ إِلاَّ بِمَكَّةَ وَمَا كَانَ مِنْ ذَلِكَ نُسُكًا فَهُوَ يَكُونُ حَيْثُ أَحَبَّ صَاحِبُ النُّسُكِ ‏.‏
