“When the Messenger of Allah (saw) said the Salam, he would sit only for as long as it took to say: ‘Allahumma Antas-Salam wa minkas-salam. Tabarakta ya Dhal-jalali wal- ikram. (O Allah, You are As-Salam, From You is all peace, blessed are You O Possessor of majesty and honour).’”

“Subhan Allahi Rabbil-‘alamin (Glory is to Allah, the Lord of the worlds),” repeating that for a while, then he said: Subhan Allahi wa bihamdihi (Glory and praise is to Allah).”

when he was in distress, the Prophet of Allah (saws) would supplicate: “There is none worthy of worship except Allah, the Forbearing, the Wise, there is none worthy of worship except Allah, the Lord of the Magnificent Throne, there is none worthy of worship except Allah, the Lord of the heavens and the earth, and the Lord of the Noble Throne (Lā ilāha illallāh al-`aliyyul ḥalīm, lā ilāha illallāh, rabbul-`arshil-`aẓīm, lā ilāha illallāh, rabbus-samāwāti wal-arḍi wa rabbul-`arshil-karīm).”

“My father narrated to me, from my grandfather, that he heard the Prophet (saws) say: ‘Whoever says: “I seek forgiveness from Allah, the Magnificent, whom there is none worthy of worship but Him, the Living, Al-Qayyum, and I repent to him,” (Astaghfirullāhal-`Aẓīm alladhī lā ilāha illā huwal-Ḥayyul-Qayyūmu wa atūbu ilaih) then Allah will forgive him, even if he fled from battle.’”

Messenger of Allah (PBUH) said, "Let none of you wish for death on account of an affliction that befalls him. If he has no alternative, let him pray: 'Allahumma ahyine ma kanatil-hayatu khairan li, wa tawaffani idha kanatil-wafatu khairan li (O Allah! Give my life so long as the life is good for me, and take away my life if death is good for me)'."

[Al-Bukhari and Muslim].

The Prophet (PBUH) said, "If anyone intends to have (sexual intercourse) with his wife, he should say: "Bismillah! Allahumma janibnash-Shaitana, wa jannibish-Shaitana ma razaqtana (In the Name of Allah, O Allah! Keep us away from Satan and keep Satan away from what You have bestowed upon us);' and if Allah has ordained a child for them, Satan will never harm him."

[Al-Bukhari and Muslim].

I said to ‘AbdurRahman bin ‘Awf: How could you swear allegiance to ‘Uthman (رضي الله عنه) and not to `Ali (رضي الله عنه)? He said: It is not my fault. I started with `Ali and said: I swear allegiance to you in accordance with the Book of Allah, the Sunnah of His Messenger, and the way of Abu Bakr and ʼUmar (رضي الله عنهما) . He said: As much as I can. Then I offered it to `Uthman (رضي الله عنه) and he accepted it.

Yahya related to me from Malik that he had heard that Abdullah ibn Abbas used to say, "The least difficult thing acceptable as a sacrificial animal is a sheep."

Malik said, "That is what I like most out of what I have heard about the matter, because Allah, the Blessed and Exalted, says in His Book, 'O you who trust, do not kill game while you are in ihram. Whoever of you kills it intentionally, there shall be repayment the like of what he has slain, from livestock, as shall be judged by two men of justice among you, a sacrificial animal which will reach the Kaba, or food for poor people, or the equivalent of that in fasting,' (Sura 5 ayat 95) and a sheep is one of the animals which is judged to be acceptable as a sacrifice. Allah has called it a sacrificial animal, and there is no dispute among us about the matter. How, indeed, could anyone be in doubt about the matter? A sheep is the kaffara for anything which does not reach the extent of something for which a camel or a cow would be the kaffara, and the kaffara for something which does not reach the extent of something for which a sheep would be the kaffara is fasting, or feeding poor people."

the Messenger of Allah (saas) said: "Whoever says in the morning: 'La illaha illalahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, wa Huwa 'ala kulli shay'in Qadir (None has the right to be worshipped but Allah alone, with no partner or associate. His is the dominion and all praise is to Him, and He is Able to all things)' - he will have (a reward) equal to freeing a slave among the sons of Isma'il, ten bad deeds will be erased from (his record), he will be raised (in status) ten degrees, and he will have protection against Satan until evening comes. When evening comes, (if he says likewise) he will have the same until morning comes.'" (Sahih)He (one of the narrators) said: "A man saw the Messenger of Allah (saas) in a dream and said: 'O Messenger of Allah, Abu 'Ayyash narrated such and such from you.' He said: 'Abu 'Ayyash spoke the truth.'"

"If anyone of you sneezes, let him say: Alhamdulillah (praise be to Allah). Those around him should respond by saying: Yarhamkullah (may Allah have mercy on you). And he should respond by saying: "Yahdikum Allah wa yuslaha balakum (may Allah Guide you and set right your state)."

that he married a woman from Banu Jusham, and they said: “May you live in harmony and have many sons.” He said: “Do not say that, rather say what the Messenger of Allah said: 'Allahumma barik lahum wa barik `alaihim (O Allah, bless them and bestow blessings upon them).' ”

“Allahumma Antas-Salam wa minkas-salam tabarakta ya Dhal-jalali wal- ikram” (O Allah, You are As-Salam and from You is all peace, Blessed are You O Possessor of majesty and honour).”

Ḥasbunallāhu wa ni`mal-wakīl. Allah is sufficient for us and the best of those on whom to depend. Reference: Al-Bukhari, 5/172.

Allah’s Messenger (saw) said, “If one after performing ablution completely recites the following supplication: (Ash-hadu an la ilaha ill-Allahu wahdahu la sharika lahu, wa ash hadu anna Muhammadan ‘abduhu wa Rasuluhu) ‘I testify that there is no one worthy of worship but Allah, He is Alone and has no partner and Muhammad (saw) is his slave and Messenger’, all the eight gates of Paradise will be opened for him and he may enter through any gate he wishes”.

Allāhumma innī a`ūdhu biriḍāka min sakhaṭika, wa bimu`āfātika min `uqūbatika wa a`ūdhu bika minka lā uḥṣī thanā'an `alayka anta kamā athnayta `alā nafsika. O Allah, I seek protection in Your pleasure from Your anger, and I seek protection in Your forgiveness from Your punishment. I seek protection in You from You. I cannot count Your praises. You are as You have praised Yourself. Reference: Muslim 1/352.

There is none worthy of worship but Allah, the Mighty, the Forbearing. There is none worthy of worship but Allah, Lord of the Magnificent Throne. There is none worthy of worship but Allah, Lord of the heavens and Lord of the earth, and Lord of the Noble Throne. Reference: Al-Bukhari 8/154, Muslim 4/2092

Rabbanā ātinā fid-dunyā ḥasanah wa fi ‘l-ākhirati ḥasanah wa qinā `adhāban-nār. Our Lord, grant us the good things in this world, and the good things in the next life, and save us from the punishment of the Fire. Reference: Abu Dawud 2/179, Ahmad 3/411, Al-Baghawi, Sharhus-Sunnah 7/128. Al-Albani graded it good in Sahih Abu Dawud 1/354. The Ayat is from Surat Al-Baqarah, 2:201.

Bismillāh (three times). Then say seven times: A`ūdhu billāhi wa qudratihi min sharri mā ajidu wa uḥādhir. Put your hand on the place where you feel pain and say: With the Name of Allah (three times). Then say seven times: I seek refuge in Allah and in His Power from the evil of what I find and of what I guard against. Reference: Muslim 4/1728.

Allah's Messenger said to Al-Abbas: "O uncle! Shall I not give to you, shall I not present to you, shall I not benefit you?" He said: "Of course, O Messenger of Allah!" He said: "O uncle! Pray four Rak'ah, reciting in each Rak'ah Fatihatil-Kitab and a Surah. When you are finished your recitation then say: Allahu Akbar, wal-hamdulilah, wa Subhan-Allah, [Wa La Ilaha illallah] 'Allah is Greatest, and all praise is due to Allah, and Glorious is Allah, [and there is none worthy of worship except Allah].' fifteen times before you bow. Then bow and say it ten times, then raise your head and say it ten times. Then prostrate [the second time] and say it ten times. Then raise your head and say it ten times before standing. That is seventy-five in every Rak'ah, which is three-hundred in four Rak'ah. If your sins were like a heap of sand then Allah would forgive you." He said: "O Messenger if Allah! Who is able to say that every day?" He said: "If you can not say it every day then say it every Friday, and if you are not able to say it every Friday then say it every month." And he did not stop saying that until he said: "Then say it every year."

I spent a night with my maternal aunt Maimuna when the Prophet was with her. After talking to his family for a time he had a sleep, then when the last third of the night came, or a little later, he sat up, looked at the sky, and recited, “In the creation of the heavens and the earth and the alternation of night and day there are indeed signs for people of understanding,"(Al-Qur’an; 3:190) to the end of the sura. Then getting up and going to the bucket, he loosened its cord and poured some water into a bowl, then performed a good ablution between the two extremes, not going to great length, and when he had done it fully he stood up and prayed. I got up, and when I had performed ablution I stood at his left side, whereupon he took me by the ear and made me go round to his right side. His prayer was altogether thirteen rak'as. Then he lay down and slept, and he snored as was his custom. When Bilal made the call to prayer for him he prayed without performing ablution, and his supplication included these words, “O God, place light in my heart, light in my eyesight, light in my hearing, light on my right hand, light on my left hand, light above me, light below me, light in front of me, light behind me, and grant me light." Some added, “and light in my tongue," and mentioned, “my joints, my flesh, my blood, my hair, my skin." (Bukhari and Muslim.) In a version by both of them he said, “Place light in my soul, and give me abundant light." In another by Muslim he said, “O God, give me light."

“My father heard me while I was saying: “O Allah, I seek refuge in You from sadness and laziness and the punishment of the grave (Allāhumma, innī a`ūdhu bika minal-hammi wal-kasali wa `adhābil-qabr).’ He said: ‘O my son, from who did you hear this?’” He said: “I said: ‘I heard you saying them.’ He said: ‘Stick to them, for indeed, I heard the Messenger of Allah (saws) saying them.’”

Messenger of Allah (PBUH) said, "How can I feel at ease when the Angel of the Trumpet, (Israfil) has put his lips to the Trumpet and is waiting for the order to blow it". He (PBUH) perceived as if this had shocked his Companions, so he (PBUH) told them to seek comfort through reciting: 'Hasbunallah wa ni'mal-Wakil [Allah (Alone) is Sufficient for us, and He is the Best Disposer of affairs (for us)]".

[At-Tirmidhi, who classified it as Hadith Hasan].

Messenger of Allah (PBUH) was sitting while a man was eating food. That man did not mention the Name of Allah (before commencing to eat) till only a morsel of food was left. When he raised it to his mouth, he said: "Bismillah awwalahu wa akhirahu (With the Name of Allah, in the beginning and in the end)." Messenger of Allah (PBUH) smiled at this and said, "Satan had been eating with him but when he mentioned the Name of Allah, Satan vomited all that was in his stomach."

[Abu Dawud and An-Nasa'i].

One of the supplications of the Messenger of Allah (PBUH) was: "Allahumma inni as'aluka mujibati rahmatika, wa 'aza'ima maghfiratika, was-salamata min kulli ithmin, wal-ghanimata min kulli birrin, wal-fawza bil- jannati, wannajata mina-nar (O Allah! I beg You for that which incites Your Mercy and the means of Your forgiveness, safety from every sin, the benefit from every good deed, success in attaining Jannah and deliverance from Fire)."

[Al-Hakim].

The Messenger of Allah (PBUH) said, "He who says upon hearing the Adhan: 'Allahumma Rabba hadhihid-da'wati-ttammati, was-salatil-qa'imati, ati Muhammadanil-wasilata wal-fadhilata, wab'athu maqaman mahmuda nilladhi wa 'adtahu [O Allah, Rubb of this perfect call (Da'wah) and of the established prayer (As-Salat), grant Muhammad the Wasilah and superiority, and raise him up to a praiseworthy position which You have promised him]', it becomes incumbent upon me to intercede for him on the Day of Resurrection."

[Al- Bukhari].

the Messenger of Allah (SAW) told them: "One of the slaves of Allah said: 'Ya Rabb! Lakal-hamdu kama yanbagi li-jalali Wajhika wa li 'azima sultanika (O Lord, to You is praise as befits the Glory of Your Face and the greatness of Your Might.)' The angels were uncertain and did not know how to write this down, so they ascended to heaven and said: 'O our Lord, Your slave has said a word that we do not know how to write down.' Allah said - and He knows best what His slave said - 'What did My slave say?' They said: 'O Lord, he said "Ya Rabb! Lakal-hamdu kama yanbagi li-jalali Wajhika wa li'azima sultanika (O Lord, to You is praise as befits the Glory of Your Face and the greatness of your Might).'" Allah said to them: 'Write it down as My slave said it, until he meets Me and I shall reward him for it.'"

“I heard Ibn Abi Laila say: ‘Ka’b bin ‘Ujrah met me and said: “Shall I not give you a gift? The Messenger of Allah (saw) came out to us and we said: ‘We know what it means to send greetings on you, but what does it mean to send peace and blessings upon you?’ He said: ‘Say: Allahumma salli ‘ala Muhammadin wa ‘ala ali Muhammadin, kama sallayta ‘ala Ibrahima, innaka Hamidun Majid; Allahumma barik ‘ala Muhammadin wa ‘ala ali Muhammadin, kama barakta ‘ala Ibrahima, innaka Hamidun Majid (O Allah, send your grace, honour and mercy upon Muhammad and upon the family of Muhammad, as You sent Your grace, honour and mercy upon Ibrahim, You are indeed Praiseworthy, Most Glorious. O Allah, send Your blessings upon Muhammad and the family of Muhammad, as You sent Your blessings upon Ibrahim, You are indeed Praiseworthy, Most Glorious).’”

Allāhumma `abduka wabnu 'amatik iḥtāja ilā raḥmatik, wa anta ghaniyyun `an `adhābih, in kāna muḥsinan fazid fī ḥasanātih, wa in kāna musī'an fatajāwaz `anh. O Allah, Your male slave and the child of Your female slave is in need of Your mercy, and You are not in need of his torment. If he was pious then increase his rewards and if he was a transgressor then pardon him. Reference: Al-Hakim 1/359 who graded it authentic and Ath-Thahabi agreed with him. See also Al-Albani, Ahkamul-Jana'iz, p. 125.

“The Messenger of Allah (saw) used to say: ‘Allahumma inni a’udhu bika minal-ju’, fa innahu bi’sad- daji’, wa a’udhu bika minal-khiyanah, fa innaha bi’satil-bitanah (O Allah, I seek refuge with You from hunger, for it is a bad companion, and I seek refuge with You from treachery, for it is a bad thing to hide in one’s heart).’”

The Prophet (SAW) said: “Whoever was stricken with a calamity and when he remembers it he says ‘Inna lillahi, wa inna ilayhi raji’un (Truly, to Allah we belong and truly, to Him we shall return),’ even though it happened a long time ago, Allah will record for him a reward like that of the day it befell him.”

He is Allah (the) One. The Self-Sufficient Master, Whom all creatures need, He begets not nor was He begotten, and there is none equal to Him. With the Name of Allah, the Most Gracious, the Most Merciful. Say: I seek refuge with (Allah) the Lord of the daybreak, from the evil of what He has created, and from the evil of the darkening (night) as it comes with its darkness, and from the evil of those who practice witchcraft when they blow in the knots, and from the evil of the envier when he envies. With the Name of Allah, the Most Gracious, the Most Merciful. Say: I seek refuge with (Allah) the Lord of mankind, the King of mankind, the God of mankind, from the evil of the whisperer who withdraws, who whispers in the breasts of mankind, of jinns and men. Reference: Al-Ikhlas 112:1-4, Al-Falaq 113:1-5, An-Nas 114:1-6. Whoever recites these three times in the morning and in the evening, they will suffice him (as a protection) against everything. The Hadith was reported by Abu Dawud 4/322, and At-Tirmidhi 5/567. See Al-Albani's Sahih At-Tirmidhi 3/182.

“We were with the Messenger of Allah (saws) on a military expedition. When we returned, we overlooked Al-Madinah, and the people were pronouncing the Takbīr, and they raised their voices with it. The Messenger of Allah (saws) said: ‘Verily, your Lord is not deaf nor absent, He is between you and between the heads of your mounts.’ Then he said: ‘O `Abdullah bin Qais, should I not inform you of a treasure from the treasures of Paradise: Lā ḥawla wa lā quwwata illā billāh (There is no might or power except by Allah).’”

“I was sleeping at the side of the Messenger of Allah (saws), then I lost him during the night. So I felt around for him, and my hand fell upon his feet while he was prostrating, and he was saying: ‘I seek refuge in Your pleasure from Your anger, and in Your pardon from Your punishment. I cannot count Your praises. You are as You have praised Yourself (A`ūdhu biriḍāka min sakhaṭika wa bi mu`āfātika min `uqūbatika, lā uḥṣi thanā’an `alaika anta kamā athnaita `alā nafsik).’”

that a Mukatib came to him and said: “Indeed I am not capable of my Kitabah so aid me.” He said: “Should I not teach you words that the Messenger of Allah (saws) taught me? If you had a debt upon you similar to the mountain of Sir, Allah would fulfill it for you. He said: ‘Say: O Allah, suffice me with Your lawful against Your prohibited, and make me independent of all those besides You (Allāhummakfinī biḥalālika `an ḥarāmika, wa aghninī bi faḍlika `amman siwāka).’”

“Thabit Al-Bunani narrated to me, he said to me: ‘O Muhammad, when you suffer from some ailment, then place your hand at the place of the ailment, then say: “In the Name of Allah, I seek refuge in Allah’s might and power from the evil of this pain I feel (Bismillāh, a`ūdhu bi-`izzatillāhi wa qudratihī min sharri mā ajidu min waja`ī hādhā).” Then lift your hand and repeat that an odd number of times. For indeed, Anas bin Malik narrated to me, that the Messenger of Allah (saws) narrated that to him.’”

The Messenger of Allah (PBUH) said, "He who says: 'Astaghfir ullah-alladhi la ilaha illa Huwal-Haiyul-Qayyumu, wa atubu ilaihi (I seek the forgiveness of Allah, there is no true god except Allah, the Ever-Living, the Self- Subsisting, and I turn to Him in repentance),' his sins will be forgiven even if he should have run away from the battlefield (while he was engaged in fighting for the Cause of Allah)."

[Abu Dawud, At-Tirmidhi and Al-Hakim (on conditions of Al-Bukhari and Muslim for accepting Hadith)].

Ibn ‘Umar said that God’s messenger used to perform two rak’as in Dhul Hulaifa, then when the she-camel stood up with him on its back at the mosque of Dhul Hulaifa, he shouted these words, saying, “Lubbaik, O God, labbaik labbaik wa-sa‘daik ('Always ready to obey.’) ; good is in Thy hands; labbaik; desire and action are directed towards Thee. (Bukhari and Muslim, the wording being Muslim's.) (It is strange to find a tradition from Bukhari and Muslim in section (b). The author has explained in his introduction that section (a) is confined to Bukhari and Muslim and section (b) to other authorities)

Muṭirnā bifaḍlillāhi wa raḥmatih. We have been given rain by the grace and mercy of Allah. Reference: Al-Bukhari 1/205, Muslim 1/83.

The Messenger of Allah (SAW) entered the Masjid, then a man entered and prayed, then he came and greeted the Messenger of Allah (SAW) with Salam. The Messenger of Allah (SAW) returned his greeting and said: Go back and pray, for you have not prayed." So he went back and prayed as he has prayed before, then he came to the Prophet (SAW) and greeted him with Salam, and the Messenger of Allah (SAW) said to him: "Wa alaika as-salam (and upon you be peace). Go back and pray for you have not prayed." He did that three times, then the man said: "By the One Who sent you with the truth, I cannot do any better than that; teach me." He said: "When you stand to pray, say the Takbir, then recite whatever is easy for you of Quran. Then bow until you have tranquility in your bowing, then stand up until you are standing straight. Then prostrate until you have tranquility in your prostration, then sit up until you have tranquility in your sitting. Then do that throughout your entire prayer."

"If a person says: 'La ilaha illallahu wa Allahu Akbar (None has the right to be worshipped but Allah and Allah is the Most Great),'Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, and I am the Most Great.' If a person says: La ilaha Illallah wahdahu (There is none worthy of worship except Allah alone), Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, alone.' If he says, La ilaha illallahu la sharikalahu (There is none worthy of worship except Allah with no partner or associate),' Allah says: 'My slave has spoken the truth; there is none worthy of worship except I, with no partner or associate.' If he says: 'La illah illallah, lahul mulku wa lahul hamdu (There is none worthy of worship except Allah, all dominion is His and all praise is to Him),' Allah says: 'My slave has spoken the truth; there is none of worthy of worship except I, all dominion Mine and all praise is due to Me.' If he says: ' La illaha illallah, la hawla wa la quwwata illa billah (There is none worthy of worship and there is no power and no strength except with Allah),' Allah says: 'My slave has spoken then truth; there is none worthy of worship except I, and tehre is no power and no strength except with Me.' One of the narrators Abu Ishaq said: "Then Agharr (another narrator) said something that I did not understand. I said to Abu Jafar: 'What did he say?' He said: 'Whoever is blessed with (the ability to say) them (these words) at the time of death, the Fire will not touch him.'"

"I asked 'Aishah about a supplication that the Messenger of Allah (saas) used to say. She said that he used to say: 'Allahumma inni a'udhu bika min sharri ma 'amiltu, wa min sharri ma lam a'mal (O Allah, I seek refuge with You from the evil of that which I have done and the evil of that which I have not done).'"

“The Messenger of Allah (saw) said: ‘The Imam is appointed to be followed. When he says Allahu Akbar, then say Allahu Akbar; when he bows, then bow; when he says Sami’ Allahu liman hamidah, then say Rabbana wa lakal-hamd; when he prostrates then prostrate; if he prays standing, then pray standing, and if he prays sitting down then pray sitting down.”

“The stronger believer is better and more beloved to Allah than the weak believer, although both are good. Strive to seek that which will benefit you and do not feel helpless. If something overwhelms you, then say: Qaddarallah, wa ma sha'a fa’al (It is the decree of Allah and what He wills He does). And beware of (saying) ‘If only,’ for ‘If only’ opens the door to Satan.”

Lā ilāha illallāh al-Wāḥidul-Qahhār, Rabbus-samāwāti wa ‘l-arḍi wa mā baynahuma al-`Azīzul-Ghaffār. There is none worthy of worship but Allah, the One, the Victorious, Lord of the heavens and the earth and all that is between them, the All-Mighty, the All-Forgiving. Reference: This is to be said if you turn over in bed during the night. Al-Hakim graded it authentic and Ath-Thahabi agreed 1/540. Also see An-Nasa'i, 'Amalul-Yawm wal-Laylah, and Ibn As-Sunni.

O Allah, forgive [name of the person] and elevate his station among those who are guided. Send him along the path of those who came before, and forgive us and him, O Lord of the worlds. Enlarge for him his grave, and shed light upon him in it. Reference: Muslim 2/634.

The best invocation is that of the Day of Arafat, and the best that anyone can say is what I and the Prophets before me have said: Lā 'ilāha 'illallāhu waḥdahu lā sharīka lahu, lahul-mulku wa lahul-ḥamdu wa huwa `alā kulli shay'in qadīr. None has the right to be worshipped but Allah Alone, Who has no partner. His is the dominion and His is the praise, and He is Able to do all things. Reference: At-Tirmidhi. Al-Albani graded it good in Sahih At-Tirmidhi 3/184, and also Silsilatul-'Ahadith As-Sahihah 4/6.

“I witnessed Ali having an animal brought to him to ride. When he placed his foot in the stirrup he said: ‘In the Name of Allah,’ (Bismillāh) [three times]. So then, once he had ascended upon its back, he said: ‘All praise is due to Allah.’ (Al-ḥamdulillāh) then he said: Glory is to Him Who has subjected this to us, and we were not able to do it. And, surely, to our Lord are we returning (Subḥān alladhī sakh-khara lanā hādhā wa mā kunnā lahū muqrinīn. Wa innā ilā rabbinā lamunqalibūn). Then he said: ‘All praise is due to Allah (Al-ḥamdulillāh)’ – three times – and ‘Allah is the Greatest (Allāhu Akbar)’ – three times – ‘Glory is to You, indeed I have wronged myself, so forgive me, for indeed none forgives sins except You (Subḥānaka innī qad ẓalamtu nafsī faghfirlī fa-innahū lā yaghfirudh-dhunūba illā ant).’ Then he laughed. So I said: ‘O Commander of the Believer! What caused you to laugh?’ He said: ‘I saw the Messenger of Allah do as I did, then he (saws) laughed, so I said, ‘What cause you to laugh?’ He said: ‘Indeed, your Lord is very pleased with His worshipper when he says: “O my Lord, forgive me my sins, indeed, no one other than You forgives sins.”
