Jami` at-Tirmidhi

"The Prophet (S) saw a boy of ours - called Aflah - blowing when he prostrated. So he said: 'O Aflah! Put your face in the dirt.'"

"A boy of ours named Rabah."

"The Prophet (S) prohibited than a man to pray with his hands on his hip."

He passed by Al-Hasan bin Ali while he was performing Salat and he had gathered his locks at the back of his head, so he (Abu Rafi) undid them, and Al-Hasan turned to him angrily. He said: "Resume your Salat and do not be angry, for indeed I heard Allah's Messenger (S) saying: 'That is the seat of Ash-Shaitan.'"

Allah's Messenger (S) said: "As-Salat is two and two, with a Tashahhud for every two Rak`ah, with humility, imploring, having a sense of tranquility, pleading and showing helplessness and stretching out your hand" - he said: raising them - "to your Lord, with the insides of them facing your face, saying: 'O Lord! O Lord! And whoever does not do this, then it is like this or that."

Allah's Messenger (S) said: "When one of you performs Wudu and does so well, then he leaves intending to go to the Masjid, then let him not intertwine his fingers, for indeed he is in Salat."

"It was said to the Prophet (S): 'Which Salat is most virtuous?' He said: 'That with the longest Qunut.'"

"I met Thawban the freed slave of Allah's Messenger (S) and said to him, 'Guide me to a deed by which Allah benefit me, and for which Allah will admit me into Paradise.' He was silent for quite a while, then he turned to me and said: 'Perform prostrations, for I heard Allah's Messenger (S) saying: 'No worshipper performs a prostration to Allah except that by it, Allah will raise him a level, and erase a sin from him for it.'"

"I met Abu Ad-Darda, and I asked him what I had asked Thawban, so he said: 'Perform prostrations, for I heard Allah's Messenger saying: 'No worshipper performs a prostration to Allah except that by it Allah will raise him a level, and erase a sin from him for it.'"

"Allah's Messenger (S) ordered killing the two black things in Salat; the snake and the scorpion."

"The Prophet (S) stood for the Zuhr prayer, and he had a sitting to perform, so when he completed his Salat, he performed two prostrations, saying the Takbir for each prostration. So he was sitting before saying the Salam, and the people prostrated with him in place of the sitting he forgot."

The Hadith of Ibn Buhainah is a Hasan 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 (ﷺ) 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 Ibn Buhainah (because) Malik is his father and Buhainah is his mother. I was informed of this by Ishaq bin Mansur from 'Ali 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 (ﷺ) 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 (ﷺ), 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 (ﷺ), 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.

"The Prophet (S) prayed five (Rakah) for Zuhr, so it was said to him: 'Has the prayer been added to, or have you merely forgotten?' So he (S) performed two prostrations after he had said the Salam."

"The Prophet (S) performed two prostrations for As-Sahw after talking."

"The Prophet (S) performed two prostrations after the Salam."

the Prophet (S) led them in Salat he forgot (something) so he performed two prostrations, then the Tashah-hud, then the Salam.

"I said to Abu Sa'eed: 'One of us performs Salat and we do not know how (much) we prayed.' So he said: 'Allah's Messenger (S) said: "When one of you performs Salat and he does now know how (much) he prayed then let him perform two prostrations while he is sitting."

Allah's Messenger (S) said: "Indeed the Shaitan comes to one of you in his Salat confusing him until he does now know how much he has prayed. When one of you experiences that then let him perform two prostrations while sitting."

"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."
