"When we sat during the prayer with the Messenger of Allah (ﷺ), we used to say: 'Peace (salam) be upon Allah(SWT), peace be upon so-and-so and so-and-so.' The Messenger of Allah (ﷺ) said: 'Do not say peace (salam) be upon Allah (SWT), for Allah (SWT) is As-Salam (the Source of peace; the One free from all faults). Rather say: At-tahiyyatu lillahi wasalawatu wat-tayibaat, as-salamu 'alaika ayah-Nabiyyu wa rahmatAllahi wa baraktuhu. As-salamu 'alaina a 'ala ibad illahis-salihin (All compliments, prayers and pure words are due to Allah. Peace be upon you O Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous slaves of Allah.) If you say that, it will be for every righteous slave in the heavens and on earth, "ashadu an la ilaha ill Allah, wa ashhadu anna Muhammadan 'abduhu wa rasuluhu (I bear witness that that none has the right to be worshipped except Allah, and I bear witness that Muhammad is His slave and messenger.) Then let him choose any supplication that he likes to say after that.'"

"Umm Sulaim came to the Prophet (ﷺ) and said: 'O Messenger of Allah (ﷺ), teach me some words that I may supplicate with during my prayer.' He said: 'Glorify Allah (by saying SubhanAllah) ten times, and praise Him (by saying Alhamdulilah) ten times, and magnify Him (by saying Allahu Akbar) ten times, then ask Him for what you need; He will say: 'Yes, yes.'

"I was sitting with the Messenger of Allah (ﷺ) and a man was standing and praying. When he bowed, prostrated and recited the tashahhud, he supplicated, and in his supplication he said: "Allahumma inni as'aluka bi-anna lakal-hamd, lailaha illa ant, al-mannanu badi'us-samawati wal-ard, ya dhal-jalali wal-ikram! Ya hayyu ya qayyum! Inni as'aluka. (O Allah, indeed I ask You since all praise is due to You, there is none worthy of worship but You, the Bestower, the Creator of the heavens and earth, O Possessor of majesty and honor, O Ever-living, O-Eternal, I ask of You.)' The Prophet (ﷺ) said: 'Do you know what he has supplicated with?' They said: "Allah (SWT) and His Messenger know best." He said: 'By the One in Whose Hand is my soul, he called upon Allah by His greatest Name, which, if He is called by it, He responds, and if He is asked by it, He gives.'"

Mihjan bin Al-Adra' narrated to him that the Messenger of Allah (ﷺ) entered the masjid and there was a man who had finished his prayer and he was reciting the tashahhud. He said: "Allahumma inni as'aluka ya Allah! Bi-annakal-Wahidul-Ahad us-Samad, alladhi lam yalid wa lam yowled, wa lam yakun lahu kufuwan ahad, an taghfirali dhunubi, innaka antal-Ghafurur-Rahim (O Allah, I ask of You, O Allah, as You are the One, the Only, the Self-Sufficient Master, Who begets not nor was He begotten, and there is None equal or comparable to Him, forgive me my sins, for You are the Oft-Forgiving, Most Merciful.)" The Messenger of Allah (ﷺ) said: "He has been forgiven," three times.

"Teach me a supplication that I may recite in my prayer." He said: "Say: 'Alahumma inni zalamtu afsi zulman kathiran wa la yaghfirudhunub illa anta faghfirli maghfiratan min 'indika warhamni innaka antalGhafurur-Rahim (O Allah, verily I have wronged myself much and there is None who forgives sins except You. Grant me forgiveness from You and have mercy on me for You are the Oft-Forgiving, Most Merciful.)'"

"The Messenger of Allah (ﷺ) took my hand and said: 'I love you, O Mu'adh!' I said: 'And I love you, O Messenger of Allah (ﷺ).' Then the Messenger of Allah (ﷺ) said: 'Never forget to say in every prayer: Rabbi a'inni 'ala dhikrika wa shukrika wa husni 'ibadatik (My Lord, help me to remember You, give thanks to You and worship You well.)"

The Messenger of Allah (ﷺ) used to say in his prayer: "Allahumma inni as'aluka at-thabbuta fi al-amr wal-'azimata 'alar-rushdi wa as'aluka shukr ni'matik wa husna 'ibadatik wa as'aluka qalban saliman wa lisanan sadiqan wa as'aluka min khairi ma at'lamu wa author bika min sharri ma at'lamu wastaghfiruka lima ta'lam (O Allah, I ask You for steadfastness in all my affairs and determination in following the right path, I ask You to make me thankful for Your blessings and to make me worship You properly. I ask You for a sound heart and a truthful tongue. I ask You for the best of what You know and I seek refuge in You from the worst of what You know and I seek Your forgiveness for what You know.)"

"Ammar bin Yasir led us in prayer and he made it brief. Some of the people said to him: 'You made the prayer sort (or brief).' He said: 'Nevertheless I still recited supplications that I heard from the Messenger of Allah (ﷺ).' When he got up and left, a man -- he was my father but he did not name himself -- followed him and asked him about that supplication, then he came and told the people: "Allāhumma bi `ilmikal-ghaiba wa qudratika 'alal-khalqi aḥyinī mā `alimtal-ḥayāta khairan lī, wa tawaffanī idhā `alimtal-wafāta khairan lī. Allāhumma wa 'as'aluka khashyataka fil-ghaibi wash-shahādati wa 'as'aluka kalimatal-ḥaqqi fir-riḍā'i wal ghaḍab, wa as'alukal-qaṣda fil faqri wal-ghina, wa 'as'aluka na`īman lā yanfadu wa 'as'aluka qurrata `ainin lā tanqaṭi`u wa as'alukar-riḍā'i ba`dal-qaḍā'i wa 'as'aluka bardal `aishi ba`dal-mawti, wa 'as'aluka ladhdhatan-naẓari ilā wajhika wash-shawqa ilā liqā'ika fī ghairi ḍarrā'a muḍirratin wa lā fitnatin muḍillatin, Allāhumma zayyinnā bizīnatil-īmāni waj`alna hudātan muhtadīn (O Allah, by Your knowledge of the unseen and Your power over creation, keep me alive so long as You know that living is good for me and cause me to die when You know that death is better for me. O Allah, cause me to fear You in secret and in public. I ask You to make me true in speech in times of pleasure and of anger. I ask You to make me moderate in times of wealth and poverty. And I ask You for everlasting delight and joy that will never cease. I ask You to make me pleased with that which You have decreed and for an easy life after death. I askYou for the sweetness of looking upon Your face and a longing to meet You in a manner that does not entail a calamity that will bring about harm or a trial that will cause deviation. O Allah, beautify us with the adornment of faith and make us among those who guide and are rightly guided."

"Ammar bin Yasir led the people in prayer and he made the prayer short. It was as if they disliked that, so he said: 'Did I not do bowing and prostration properly?' They said: 'Yes.' He said: 'And I said a supplication that the Prophet (ﷺ) used to say:Allahumma bi 'ilmikal-ghaiba wa qudratika 'alal-khalqi ahini ma 'alimtal-hayata khairan li, wa tawaffani idha 'alimtal-wafata khairan li. Allahumma as'aluka khashyataka fil-ghaibi wash-shahadati wa as'aluka kalimatul-aqua fir-rida'i wal ghadab, wa as'alukal-qasda fil faqr wal-ghina, wa as'aluka na'iman la yanfadu wa as'aluka qurrata ainan la tanqati'u wa as'alukar-rida'i ba'dal-qada'i wa as'aluka bardal 'aishi ba'dal-mawti, wa as'aluka ladhatan-nazari ila wajhika wash-shawqa ila liqa'ika fi fitnatin mudillatin, Allahumma zayyina dizinatil-imani waj'alna hudatan muhtadin (O Allah, by Your knowledge of the unseen and Your power over creation, keep me alive so long as You know that living is good for me and cause me to die when You know that death is better for me. O Allah, cause me to fear You in secret and in public. I ask You to make me true in speech in times of pleasure and of anger. I ask You to make me moderate in times of wealth and poverty. And I ask You for everlasting delight and joy that will never cease. I ask You to make me pleased with that which You have decreed and for an easy life after death. I ask You for the sweetness of looking upon Your face and a longing to meet You in a manner that does not entail a calamity that will bring about harm or a trial that will cause deviation. O Allah, beautify us with the adornment of faith and make us among those who guide and are rightly guided."

"I said to 'Aishah: 'Tell me of a supplication that the Messenger of Allah (ﷺ) used to say in his prayer.' She said: 'Yes. The Messenger of Allah (ﷺ) used to say: Allahumma inni author 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.)'"

"I asked the Messenger of Allah (ﷺ) about the torment of the grave, and he siad: 'Yes, the torment of the grave is real.'" 'Aishah said: "After that I never saw the Messenger of Allah (ﷺ) offer any prayer but he would seek refuge with Allah (SWT) from the torment of the grave."

Aishah told him that the Messenger of Allah (ﷺ) used to say the following supplication in his prayer: Allahumma inni audhu bika min 'adhab ilqabri wa 'audhu bika min fitnatil-masihid-dajjal, wa 'audhu bika min fitnatil-mahya walmamati, Allahumma inni 'audhu bika min al-ma'thami wal-maghram ( O Allah, I seek refuge with You from the torment of the grave, and I seek refuge in You from the tribulation of the Al-Masihid-Dajjal, and I seek refuge with You from the trials of life and death. O Allah, I seek refuge in You from sin and debt.) Someone said to him: "How often you seek refuge from debt!" He said: "If a man gets into debt, when he speaks lies, and when he makes a promise, he betrays it."

"I heard Abu Hurairah say: 'The Messenger of Allah (ﷺ) said: When one of you recites the tashahhud, let him seek refuge with Allah (SWT) from our things: From the torment of hell, from the torment of the grave, from the trials of life and death and from the evils of the Dajjal. Then let him pray for himself asking whatever he wants.'"

The Messenger of Allah (ﷺ) used to say in his prayer, after the tashahhud: "The best of word is the word of Allah (SWT) and the best of guidance is the guidance of Muhammad (ﷺ)."

He saw a man praying (And his bowing and prostration) were lacking. Hudhaifah said to him: 'For how long have you been praying like this?' He said: "For forty years.' He said: 'You have not been praying for forty years and if you die praying like this, you will have died following a path other than the path of Muhammad (ﷺ). Then he said: 'It is possible for a man to pray briefly, but still do it properly."

A paternal uncle of his who was present at Badr told him, that a man entered the masjid and prayed, and the Messenger of Allah (ﷺ) was watching, but we did not realize. When he had finished, he came and greeted the Messenger of Allah (ﷺ) with salam. He said: "Go back and pray, for you have not prayed." So he went back and prayed, then he came to the Messenger of Allah (ﷺ) and he said: "Go back and pray, for you have not prayed." (This happened) two or three times. Then the man said to him: "By the One who has honored you , O Messenger of Allah (ﷺ), I have tried my best; teach me." He said: "When you get up to pray, perform wudu and do it well, then turn to face the Qiblah and say the takbir. Then recite the Quran, then bow until you are at ease in bowing. Then stand up until you are standing straight, then prostrate until you are at ease prostrating, then sit up until you are at ease sitting, then prostrate until you are at ease prostrating, then get up, and continue doing that until you have finished your prayer."

"My father narrated to me that a paternal uncle of his, who had been at Badr, said: 'I was sitting with the Messenger of Allah (ﷺ) in the masjid when a man came in and prayed two rak'ahs, then he came and greeted the Prophet (ﷺ) with salam. The Prophet (ﷺ) had been watching him as he prayed, so he returned his salam, then he said: "Go back and pray, for you have not prayed." So he went back and prayed, then he came back and greeted the Prophet (ﷺ) with salam. He returned the salam, then he said: "Go back and pray, for you have not prayed." The third or fourth time this happened, then the man said: "By the One Who revealed the Book to you, I have done my best and have tried hard; show me and teach me." He said: 'When you want to pray, perform wudu and do it well, then turn to face the Qiblah and say the takbir. Then recite the Quran, then bow until you are at ease in bowing. Then stand up until you are standing straight, then prostrate until you are at ease prostrating, then sit up until you are at ease sitting, then prostrate until you are at ease prostrating, then get up. If you complete the prayer in this manner you wil hve done it properly, and whatever you do less than this is lacking from you prayer.'"

"I said: 'O Mother of the believers! Tell me about the Witr of the Messenger of Allah (ﷺ).' She said: 'We used to prepare his siwak and water for purification, then Allah (SWT) would wake him when He willed to wake him at night. He would use the siwak and perform wudu, then pray eith rak'ahs; not sitting until the eighth rak'ah, when he would sit and remember Allah (SWT) and call upon Him. Then he would say the taslim loud enough for us to hear.'"

That the Messenger of Allah (ﷺ) used to say the taslim to his right and to his left.

"I used to see the Messenger of Allah (ﷺ) saying the taslim to his right and to his left until the whiteness of his cheek could be seen."
