The Prophet (PBUH) prohibited observing continuous voluntary fasts beyond one day.

[Al-Bukhari and Muslim].

Abu Dharr reported God’s messenger as saying, “When you fast three days in the month, Abu Dharr, fast on the thirteenth, fourteenth and fifteenth.” Tirmidhi and Nasa'i transmitted it.

Jabir said God's messenger forbade that a man should put on sandals while standing. Abu Dawad transmitted it, and Tirmidhi and Ibn Majah transmitted it on Abu Huraira’s authority.

Abu Musa al-Ash‘ari reported God’s messenger as saying, "He who plays backgammon has disobeyed God and His messenger." Ahmad and Abu Dawud transmitted it.

"Ibn 'Umar and I went to Abu Sa'eed and he narrated to us: 'the Messenger of Allah (saws) said - and I heard him with these [two] ears: "Do not sell gold for gold except kind for kind, nor sliver for silver except kind for kind, do not exchange more of one than the other, and do not sell what is not present from them for what is present."

[Abu 'Eisa said:] There are narrations on this topic from Abu Bakr, 'Umar, 'Uthman, Abu Hurairah, Hisham bin 'Amir, Al-Bara', Zaid bin Arqam, Fadalah bin 'Ubaid, Abu Bakrah, Ibn 'Umar, Abu Ad-Darda', and Bilal.

[He said:] The Hadith of Abu Sa'eed, from the Prophet (saws) [about Riba] is a Hasan Sahih Hadith.

This is acted upon according to the people of knowledge among the Companions of the Prophet (saws) and others, except for what has been related from Ibn 'Abbas; he did not see any harm in exchanging gold for gold or silver for silver, more for less, when it is done hand in hand, and he said: "Riba' is only in credit." Similar it has been related from some of his companions. It has been related that Ibn 'Abbas changed his opinion when Abu Sa'eed narrated it to him from the Prophet (saws). The first view is more correct.

And this is acted upon according to the people of knowledge [among the Companions of the Prophet (saws) and others]. It is the view of Sufyan Ath-Thawri, Ibn Al-Mubarak, Ash-Shafi'i, Ahmad, and Ishaq. It has been reported that Ibn Al-Mubarak said: "There is no difference over exchange."

We were sitting in the company of the Messenger of Allah (PBUH), and Abu Bakr and 'Umar (May Allah be pleased with them) were also present. All of a sudden the Messenger of Allah (PBUH) got up and left us. When he was late to return to us we began to worry lest he should meet with trouble in our absence. I was the first to be alarmed and set out in search of him until I came to a garden belonging to Banu-Najjar (a section of the Ansar). I went round it looking for an entrance, but failed to find one. However, I saw a stream of water flowing into the garden from a well outside. I drew myself together like a fox and slinked into the place and reached the Messenger of Allah (PBUH). He said, "Is it Abu Hurairah?" I replied in the affirmative. He asked, "What is the matter with you?" I replied, "You were sitting with us and then you left us and delayed for a time. Fearing you had met with some adversities we got alarmed. I was the first to be alarmed. So when I came to this garden, I squeezed myself like a fox and these people are coming behind me." He (the Prophet (PBUH)) gave me his sandals and said, "O Abu Hurairah! Take these sandals of mine, and whoever you meet outside this garden testifying that La ilaha illallah (There is no true god except Allah), being assured of it in his heart, give him the glad tidings that he will enter Jannah." (Abu Hurairah then narrated the Hadith in full).

[Muslim].

"I read in the Tawrah that the blessing for food is in the Wudu' after it. So I mentioned that to the Prophet (saws), telling him what I read in the Tawrah. So the Messenger of Allah (saws) said: 'The food's blessing is in the Wudu' before it and the Wudu' after it.'"

He said: There are narrations on this topic from Anas and Abu Hurairah.

[Abu 'Eisa said:] We do not know of this Hadith except as a narration of Qais bin Ar-Rabi'. Qais [bin Ar-Rabi'] was graded weak in Hadith. Abu Hashim Ar-Rumani's (a narrator in the chain) name is Yahya bin Dinar.

That he entered upon the Messenger of Allah (saws) while he has some food. He said: "Sit down O my son! Mention Allah's Name and eat with your right hand, and eat what is nearest to you."

[Abu 'Eisa said:] It has been reported from Hisham bin 'Urwah, from Abu Wajzah As-Sa'idi, from a man from Muzainah, from 'Umar bin Abu Salamah. The Companions of Hisham bin 'Urwah differed in reporting this Hadith. Abu Wajzah As-Sa'di's name is Yazid bin 'Ubaid.

From Iyas bin 'Abd al-Muzani who said: "The Prophet (saws) prohibited selling water."

[He said:] There are narrations on this topic from Jabir, Buhaisah from her father, Abu Hurairah, 'Aishah, Anas and 'Abdullah bin 'Amr.

[Abu 'Eisa said:] The Hadith is Iyas is a Hasan Sahih Hadith. This is acted upon according to most of the people of knowledge, they dislike selling water. This is the view of Ibn Al-Mubarak, Ash-Shafi'i, Ahmad, and Ishaq. Some of the people of knowledge permitted selling water, Al-Hasan al-Basri is one of them.

That the Messenger of Allah (saws) said: "The earnings of the cupper is filth, the earnings of the fornicator (from harlotry) is filth, and the price of a dog is filth."

that the Prophet (SAW) said: "None of the black heads (meaning the Children of Adam since (most of) their heads are black) before you partook of spoils of war, but fire from the heavens would be sent down upon them, consuming them." Sulaiman (one of the narrators) said "No one says this except for Abu Hurairah now. "So on the day of Badr when they had the spoils of war before it was made lawful for them, Allah [Most High] revealed: Were it not a previous ordainment from Allah, a severe torment would have touched you for what you took."

Negus presented to the Messenger of Allah (saws) two black and simple socks. He put them on; then he performed ablution and wiped over them.

Abu Dawud said: This tradition has been narrated by the people of Basrah alone.

The Prophet (saws) said: The time limit for wiping over the socks for a traveller is three days (and three nights) and for a resident it is one day and one night.

Abu Dawud said: Another version adds: Had we requested him to extend (the period of wiping), he would have extended.

Ata' said: The quilt of Aisha was stolen. She began to curse the person who had stolen it. The Prophet (saws) began to tell her: Do not lighten him.

Al-Abbas asked the Prophet (saws) about paying the sadaqah (his zakat) in advance before it became due, and he gave permission to do that.

On his father's authority, said that his grandfather reported the Messenger of Allah (saws) said: Anyone who practises medicine when he is not known as a practitioner will be held responsible.

The prophet (saws) offered the noon prayer and ascended the pulpit. Before this day he did not ascend it except on Friday. He then narrated this story. Abu Dawud said: Ibn Sudran belongs to Basrah. He was drowned in the sea along with Ibn Miswar, and no one could escape except him.

The Prophet (may peace be upon him) was brought milk that was mixed with water. A nomad Arab was on his right and Abu Bakr was on his left. He himself drank and gave it to the nomad Arab, and said: He who is on the right , then he who is on his right then he who is on his right.

When the Messenger of Allah (saws) died, the wives of the Prophet (saws) intended to send 'Uthman b. 'Affan to Abu Bakr to ask him their cost of living from (the inheritance of) the Prophet (saws). Thereupon 'Aishah said: Did not the Messenger of Allah (saws) say: We are not inherited. Whatever we leave is sadaqah.

I witnesses the Messenger of Allah (may peace be upon him) praying in a shirt.

Al-Zuhri used to deny tanning and say: Some good can be got out of it in any condition

Abu Dawud said: Al-Auza'i, Yunus and 'Uqail did not mention tanning. al-Zubaidi, Sa'id b. 'Abd al-Aziz and Hafs b. 'Abd al-'Aziz mentioned tanning.

I asked Abu Mas'ud while he was making circumambulation of the Ka'bah (about the recitation of some verses from the Qur'an). He said: The Messenger of Allah (saws) said: If anyone recited two verses from the last of Surah al-Baqarah at night, they will be sufficient for him.

He went out to relieve himself. Then I brought water for him and he performed ablution, and wiped over his turban and socks.

‘Ubaid Allah said “Marwan sent someone (Qabisah) to Fatimah and asked her (about the case). She said that she was the wife of Abu Hafs. The Prophet (saws) appointed ‘Ali as governor in a certain part of Yemen. Her husband also proceeded with him. From there he sent a message to her pronouncing one divorce that had yet remained. He commanded ‘Ayyash bin Abi Rabi’ah and Al Harith bin Hisham to provide maintenance to her. They said “By Allah there is no sustenance for her except in case she is pregnant.” She came to the Prophet(saws) who said “There is no sustenance for you except in case you are pregnant. She then asked permission to shift (from her house) and he gave her permission.” She asked “Where should I shift. Apostle of Allaah(saws)? The Apostle of Allaah(saws) said to Ibn Umm Maktum . He was blind. She would undress herself and he could not see her. She lived there till her waiting period passed. The Prophet (saws) married her to Usamah. Qabisah then returned to Marwan and narrated that to him. Marwan said “We did not hear this tradition except from a woman, so we shall follow the reliable practice on which we found the people”. When this reached Fatimah she said “between me and you is the Book of Allah”. Allaah the exalted said “Divorce them for their waiting period...” Thou knowest not it may be that Allaah will afterward bring some new thing to pass. She said “What a new thing will emerge after triple divorce.”

Abu Dawud said “A similar tradition has been narrated by Yunus on the authority of Al Zuhri. As for Al Zubaidi he narrated both traditions, the tradition of ‘Ubaid Allah in the version of Ma’mar and the tradition of Abu Salamah in the version of ‘Aqil.”

Abu Dawud said “Muhammad bin Ishaq narrated on the authority of Al Zuhri that Qabisah bin Dhuwaib transmitted to him the version which was narrated by ‘Ubaid Allah bin ‘Abd Allaah which has Qabisah then returned to Marwan and informed him about that.”

The Messenger of Allah (may peace be upon him) sent us on an expedition and made Abu ‘Ubaidah b. al-Jarrah our leader. We had to meet a caravan of the Quraish. He gave us a bag of dates as a light meal during the journey. We had nothing except that. Abu ‘Ubaidah would give each of us one date. We used to suck them as a child sucks, and drink water after that and it sufficed us that day till night. We used to beat leaves off the trees with our sticks (for food), wetted them with water and ate them. We then went to the coast of the sea. There appeared to us a body like a great mound. When we came to it, we found that it was an animal called al-anbar. Abu ‘Ubaidah said: It is a carrion, and it is not lawful for us. He then said: No, we are the Messengers of the Apostel of Allah (may peace be upon him) and we are in the path of Allah. If you are forced by necessity (to eat it), then eat it. We stayed feeding on it for one mouth, till we became fat, and we were three hundred in number. When we came to the Messenger of Allah (may peace be upon him), we mentioned it to him. He said : It is a provision which Allah has brought forth for you, and give us some to eat if you have any meat of it with you. So we sent some of it to the Messenger of Allah (may peace be upon him) and he ate (it).

She should wash at the time of the Zuhr prayer (the bath will be valid one Zuhr prayer to the next Zuhr prayer); and should perform ablution for every prayer. If there is excessive bleed gin, she should tie a cloth over her private part.

Abu Dawud said: It has been narrated by Ibn 'Umar and Anas b. Malik that she should take bath at the time of the Zuhr prayer (being valid) until the next Zuhr prayer. This tradition has also been transmuted by Dawud and 'Asim from al-Sha'bi from his wife from Qumair on the authority of 'Aishah, except that the version of Dawud has the words: "every day," and the version of 'Asim has the words: "at the time of Zuhr prayer". This is the view of Salim b. 'Abd Allah, al-Hassan, and 'Ata.

Abu Dawud said: Malik said: I think that the tradition narrated by Ibn a;-Musayyab must contain the words: "from one purification to another". But it was misunderstood and the people changed it to: "for one Zuhr prayer to another".

It has also been reported by Miswar b. 'Abd al-Malik b. Sa'id b. 'Abd al-Rahman b. Yarbu', saying: "from one purification to another," but the people changed it to: "from one zuhr to another."

The Messenger of Allah (saws) said: An oath or a vow about something over which a human being has no control, and to disobey Allah, and to break ties of relationship is not binding. If anyone takes an oath and then considers something else better than it, he should give it up, and do what is better, for leaving it is its atonement.

Abu Dawud said: All sound traditions from the Prophet (saws) say: "He should make atonement for his oath," except those versions which are not reliable.

Abu Dawud said: I said to Ahmad: Yahya b. Sa'id (al-Qattan) has transmitted this tradition from Yahya b. 'Ubaid Allah. He (Ahmad b. Hanbal) said: But he gave it up after that, and he was competent for doing it. Ahmad said: His (Yahya b. 'Ubaid Allah's) tradition are munkar (rejected) and his father is not known.

I cut the ear of a boy, or he cut my ear (the narrator is doubtful). AbuBakr then came to us to perform hajj and we got together with him. But he referred us to Umar ibn al-Khattab. Umar (ibn al-Khattab) said: This reached the extent of retaliation. Call a cupper to me so that he may retaliate. When the cupper was called, he (Umar) said: I heard the Messenger of Allah (saws) say: I gave a boy to my maternal aunt, and I hope that she will be blessed in respect of him. I said to her: Do not entrust him to a supper, nor to a goldsmith, nor to a butcher.

Abu Dawud said: This tradition has also been transmitted by 'Abd al-A'la from Ibn Ishaq who said: Abu Majidah is a man of Banu Sahm narrating from 'Umar b. al-Khattab.

You people recite this verse "You who believe, care for yourselves; he who goes astray cannot harm you when you are rightly-guided," and put it in its improper place.

Khalid's version has: We heard the Prophet (saws) say: When the people see a wrongdoer and do not prevent him, Allah will soon punish them all. Amr ibn Hushaym's version has: I heard the Messenger of Allah (saws) say: If acts of disobedience are done among any people and do not change them though the are able to do so, Allah will soon punish them all.

Adu Dawud said: This tradition has also been transmitted by Abu Usamah and a group transmitters similar to the version narrated by Khalid. The version of Shu'bah has: "If acts of obedience are done among any people who are more numerous than those who do them...."

The Prophet (saws) gave a beating with palm-branches and sandals for drinking wine and Abu Bakr gave lashes. When ‘Umar came to power, he called upon people and said to them: The people are living now near watering placing, and, according to Musaddad’s version, “near villages and watering places, so what do you say about the punishment for (drinking) wine? ‘Abd al-Rahman b. ‘Awf said: We think that you should prescribe the lightest punishment. So he fixed eight lashes for it.

Abu Dawud said: It has also been transmitted by Ibn Al 'Arubah from Qatadah from the Prophet (saws) to the effect that he gave a beating forty times with palm branches and sandals. And Shu'bah narrated it from Qatadah on the authority of Anas from Prophet (saws). This version has: He gave a beating with two palm-branches about forty times.

The Messenger of Allah (saws) addressed on the day of Conquest, or he said: On the conquest of Mecca on the ladder of the House or of the Ka'bah.

Abu Dawud said: In a similar way of Ibn 'Uyainah also transmitted it from 'Ali b. Zaid, from al-Qasim b. Rab'iah, from Ibn 'Umar, from the Prophet (saws) ; and Ayyub al-Sukhtiyani transmitted it from al-Qasim b. Rabi'ah from 'Abd Allah b. 'Amr like the tradition of Khalid. Hammad b. Salamah also transmitted it from 'Ali b. Zaid, from Ya'qub al-Sadusi, on the authority of 'Abd Allah b. 'Amr from the Prophet (saws). The statements of Zaid and of Abu Musa are similar to the tradition of the Prophet (saws) and to the tradition of 'Umar (Allah be pleased with him.)

Allah is most great, Allah is most great; I testify that there is no god but Allah. He then narrated adhan like the one contained in the tradition transmitted by Ibn Juraij from ‘Abd al-aziz b. ‘abd al-Malik to the same effect. The version Malik b. Dinar has. I asked the son of Abu Mahdhurah, saying: Narrate to me the adhan of your father narrated from the Messenger of Allah (May peace be upon him). He said: Allah is most great, Allah is most great, that is all. Similar is the version narrated by Ja’far b. Sulaiman from the son of Abd Muhdhurah from his uncle on the authority of his grandfather, excepting that he said; Then repeat and raise your voice. Allah is most great. Allah is most great.

The Messenger of Allah (saws) used to spend the middle ten days of Ramadan in retirement and devotion (i'tikaf) in the mosque. One year he had retirement and devotion in the mosque (as usual); when the twenty-first night came, and this night when he used to come out his devotion in the mosque, he said: He who has engaged himself in devotion along with me should do so during the last ten days; I saw that night, that was caused to forget it, but I have seen myself prostrating in water and mud on the morning following (that night), so seek it in the last ten days and seek it every night with an odd number. Abu sa'id said: Rain fell that night, the mosque that was thatched building dripped, and my eyes saw the Messenger of Allah (saws) with the traces of water and mud, on his forehead on the morning following the twenty-first night.

The Prophet (saws) as saying: In the morning alms are due for every bone in man's body. His salutation to everyone he meets is alms, his enjoining good is alms, his forbidding what is evil is alms, the removal of harmful thing from the way is alms, to have sexual intercourse with one's wife if alms, and two rak'ahs which one prays in the Duha serve instead of that.

Abu Dawud said: The tradition narrated by 'Abbad is more perfect (than the version narrated by Musaddad). Musaddad did not mention in his version "the command (of good) and the prohibition (of evil)". Instead, he added in his version saying: "Such and such." Ibn Ma'na added in his version: "They (the people) said: Messenger of Allah, how is that one of us fulfills his desire and still there are alms for him (i.e. is rewarded)? He replied: What do you think if you had unlawful sexual intercourse, would he not have been a sinner ?

I came to Mu'awiyah in Jerusalem. He led us in the Friday prayer. I saw that most of the people in the mosque were the Companions of the Prophet (saws). I saw them sitting in ihtiba condition, i.e. sitting on hips erecting the feet and sticking them to the stomach and holding them with hands or tying them with a cloth to the back, while the imam was giving sermon.

Abu Dawud said: Ibn 'Umar used to sit in ihtiba position while the imam gave the Friday sermon. Anas b. Malik, Shuraih, Sa'sa'ah b. Sawhan, Sa'id b. al-Musayyib, Ibrahim al-Nakha'i, Makhul, Isma'il, Ismail b. Muhammad b. Sa'd, and Nu'aim b. Sulamah said: There is no harm in sitting in ihtiba position.

Abu Dawud said: I do not know whether anyone considered it disapproved except 'Ubadah b. Nasayy.

the Prophet said: "Whoever engages in sexual intercourse with a menstruating woman, or a woman in her anus, consults a soothsayer, then he has disbelieved in what was revealed to Muhammad."

Allah's Messenger said: "In very hot weather, delay the (Zuhr) prayer until it becomes (a bit) cooler, because the severity of heat is from the raging of the Hell."

Allah's Messenger said: "The best rows for the men are the first of them, and the worst are the last of them. And the best rows for the women are the last of them, and the worst are the first of them."

the Prophet said "When the Imam says 'Amin' then (all of you) say 'Amin.' For whoever's 'Amin' concurs with the 'Amin' of the angels, then his past sins will be forgiven."

Allah's Messenger (S) said: "Whoever did not pray the two Rak'ah (before) Fajr then let him pray them after the sun has risen."

The Messenger of Allah said: "There are two joys for the fasting person: the joy when he breaks his fast, and the joy of when he meets his Lord."

The Messenger of Allah said: "When a man has two wives and he is not just between them, he will come on the Day of Judgment with one side drooping."
