Jami` at-Tirmidhi

"When one of you becomes forgetful in his Salat so that he does not know if he prayed one or two, then let him consider it one. When he does not know if he prayed three or four, then let him consider it three, and let him perform two prostrations before he says the Taslim."

"The Prophet (S) turned (finished the prayer) after two (Rak'ah), so Dhul-Yadain said: 'Has the prayer been shortened or have you forgotten O Messenger of Allah?" The Prophet (S) said: 'Is what Dhul-Yadain said the truth?' The people said yes, so Allah's Messenger (S) stood to perform the last two (Rakah) of Salat, then he said the Taslim. Then he said the Takbir and prostrated in a manner the same or longer than his (normal) prostrations."

"I said to Anas bin Malik: 'Would Allah's Messenger (S) perform Salat wearing his sandals?' He said: 'Yes.'"

"The Prophet (S) would perform the Qunut in the Subh and Maghrib prayers."

"I said to my father: 'O my father! You offered Salat behind Allah's Messenger (S), Abu Bakr, Umar, Uthman, and Ali bin Abi Talib here in Al-Kufah for about five years. Did they say the Qunut?' He said: 'It is a newly invented matter my son.'"

There exists another narration from Abu Malik with similar meaning but with different chain.

"I prayed behind Allah's Messenger (S). I sneezed and said: Al-Hamdulillah, hamdan kathiran tayyiban mubarakan fih, mubarakan alaihi kama yuhibbu Rabbana Wa Yarda (All praise is due to Alah, many good blessed praises, blessings for Him as our Lord loves and is pleased with.) When Allah's Messenger (S) prayed and turned (after finishing) he said: 'Who was the speaker during the Salat?' No one spoke. Then he said it a second time: 'Who was the speaker during the Salat?' But no one spoke. Then he said it a third time: 'Who was the speaker during the Salat?'" So Rifa'ah bin Rafi bin Afra said: "It was I, O Messenger of Allah (S)." He said: "What did you say?" He said: "I said: 'Al-Hamdulillah, hamdan kathiran tayyiban mubarakan fih, mubarakan alaihi kama yuhibbu Rabbana Wa Yarda. The Prophet (S) said: "By the One in Whose Hand is my soul! I saw thirty-some angels competing over which of then would ascend with it."

"We used to talk behind Allah's Messenger (S) during the Salat, a man among us would talk to his companions next to him until (the following) was revealed: And stand before Allah with obedience. (2:238) So we were ordered to be silent and prohibited from talking."

"I heard Ali saying: 'Indeed I am a man who, when I heard a Hadith from Allah's Messenger (S) then Allah causes me to benefit from it as much as He wills for me to benefit from it. When a man among his Companions narrated to me I ask him to swear an oath to me about it, and when he swears an oath to me I trust him. And Abu Bakr narrated to me - and Abu Bakr told the truth - he said: "I heard Allah's Messenger (S) saying: 'There is no man who commits a sin, then makes Wudu, then performs Salat, then seeks forgiveness from Allah, except that Allah forgives him.' Then he recited this Ayah: Those who when they have committed Fahishah or wronged themselves with eveil, remember Allah. (3:135) until the end of the Ayah."

Allah's Messenger (S) said: "Teach the boy Salat when he is seven years old, and beat him (if he does not pray) when he is ten."

Allah's Messenger (S) said: "When he commits Hadath - meaning a man - and he is sitting in the end of his Salat before saying the Taslim, then his Salat is acceptable."

"We were with the Prophet (S) on a journey when it started to rain on us, so the Prophet (S) said: 'Whoever wishes, let him perform Salat in his place.'"

"Some of the poor people came to Allah's Messenger (S) and said: 'O Messenger of Allah (S)! The rich pray as we pray, they fast as we fast, but they have wealth with which they free slaves and which they give in charity.' He said: 'When you perform Salat, then say: 'Subhan Allah' thirty-three times, and: 'Al-Hamdulillah' thirty-three times, and: 'Allahu Akbar' thirty-four times, and 'La ilaha illallah' ten times. With that you will have surprassed them, and none would surpass you afterwards.'"

They were with the Prophet (S) on a journey. They wound up in a narrow area when Salat became due. Then it began raining from the sky above them, and it was wet beneath them. So Allah's Messenger (S) called the Adhan while he was on his mount, and then the Iqamah, going forward on his mount. He let them in Salat by making gestures, making his prostrations lower than his bowing.

"Allah's Messenger (S) performed Salat until his feet were swollen, so it was said to him: 'You burden yourself like this, while your past and future sins have been forgiven?' He said: 'Shouldn't I be a grateful worshipper?'"

"I arrived in Al-Madinah and said: 'O Allah! Facilitate me to be in a righteous gathering.'" He said: "I sat with Abu Hurairah and said: 'Indeed I asked Allah to provide me with a righteous gathering. So narrate a hadith to me which you heard from Allah's Messenger (ﷺ) so that perhaps Allah would cause me to benefit from it.' He said: 'I heard Allah's Messenger (ﷺ) say: "Indeed the first deed by which a servant will be called to account on the Day of Resurrection is his Salat. If it is complete, he is successful and saved, but if it is defective, he has failed and lost. So if something is deficient in his obligatory (prayers) then the Lord, Mighty and Sublime says: 'Look! Are there any voluntary (prayers) for my worshipper?' So with them, what was deficient in his obligatory (prayers) will be completed. Then the rest of his deeds will be treated like that."

"Whoever is regular with twelve Rak'ah of Sunnah (prayer), Allah will build a house for him in Paradise: Four Rak'ah before Zuhr, two Rak'ah after it, two Rak'ah after Maghrib, two Rak'ah after Isha, and two Rak'ah before Fajr."

"Whoever prays twelve Rak'ah in a day and night, a house will be built from him in Paradise: Four Rak'ah before Zuhr, two Rak'ah after it, two Rak'ah after Maghrib, two Rak'ah after Isha, and two Rak'ah before Fajr in the morning Salat."

Allah's Messenger (S) said: "The two Rak'ah of Fajr are better than the world and what is in it."

"I watched the Prophet (S) for a month. In the two Rak'ah before Fajr he would recite: Say: "O you disbelievers!" and Say: "Allah is One"."

"When Allah's Messenger (S) prayed the two Rak'ah (before) Fajr if he needed something from me he would talk to me, if not, he would go to Salat."

Allah's Messenger (S) said: "There is no Salat after Al-Fajr (begins) except two prostrations."

Allah's Messenger (S) said: "When one of you prays the two Rak'ah of Fajr then let him lay down on his right (side)."

Allah's Messenger (S) said: "When the Iqamah has been called for the Salat then there is no Salat except the obligatory."

"Allah's Messenger (S) went out and the Iqamah was called for the Salat so I prayed As-Subh with him. Then the Prophet (S) turned and found me performing Salat so he said: 'Easy O Qais! Are there two prayers together?' I said: 'O Messenger of Allah! I did not perform the two Rak'ah (before) Fajr.' He said: 'Then there is no harm.'"

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 Prophet (S) would pray four Rak'ah before Az-Zuhr and two Rak'ah after it."

"I prayed two Rak'ah with the Prophet (S) before Az-Zuhr and two Rak'ah after it."

"When the Prophet (S) would not perform the four Rak'ah before Az-Zuhr he would pray them after it."

Allah's Messenger (S) said: "Whoever prays four before Az-Zuhr and four after, Allah makes him prohibited for the Fire."

She heard Allah's Messenger (S) saying: "Whoever maintains four Rak'ah before Az-Zuhr and four after it, Allah makes him prohibited for the Fire."

"Allah's Messenger (S) would pray four Rak'ah before Al-Asr separating between them with At-Taslim upon the angels that are close (to Allah) and those who follow them among the Muslims and the believers."

The Prophet (S) said: "May Allah have mercy upon a man who prays four before Al-Asr."

"I can not enumerate (how many times) I heard Allah's Messenger (S) reciting - in the two Rak'ah after Al-Maghrib and the two Rak'ah before Salatul-Fajr with: Say: "O you disbelievers!" and Say: "He is Allah the One."

"I prayed two Rak'ah after Al-Maghrib with the Prophet (S) in his house."

"I memorized ten Rak'ah from Allah's Messenger (S) which he would pray in a night and a day: Two Rak'ah before Az-Zuhr, two after it; two Rak'ah after Al-Maghrib and two Rak'ah after the latter Isha." He said: "And Hafsah narrated to me that he (S) would pray two Rak'ah before Al-Fajr."

He would pray four, and do not ask about their excellence or length, then he would pray four, and do not ask about their excellence or length, then he would pray three."

He continues in that until the illumination of Al-Fajr."
