God’s Messenger led us in prayer one day, and when he finished his prayer he faced us and said, "O people, I am your imam, so do not bow, prostrate yourselves, stand, or go away before I do, for I see you both in front of me and behind me." Muslim transmitted it.

Abu Huraira reported God’s Messenger as saying, "Do not try to go ahead of the imam. When he says ‘God is most great’ say ‘God is most great’; when he says ‘Nor of those who err’ (i.e. the end of sura 1) say ‘Amen’; when he bows bow; and when he says ‘God listens to him who praises Him’ say, ‘O God, our Lord, to Thee be the praise’." (Bukhari and Muslim, but Bukhari did not mention "and when he says, ‘Nor of those who err”’.)

Abu Huraira reported God’s Messenger as saying, “Does he who raises his head before the imam not fear that God may change his head into a donkey’s?” (Bukhari and Muslim.)

Abu Huraira reported God’s Messenger as saying, “When you come to the prayer and we are prostrating ourselves you must prostrate yourselves without reckoning it as part of your prayer; and if anyone is present at a rak'a he has been present at the prayer.” Abu Dawud transmitted it.

If anyone raises and lowers his head before the imam, his forelock is in the devil’s hand. Malik transmitted it.

Ibn ‘Umar said that a man questioned him saying, “When I pray in my house and then come to the mosque in time for prayer along with the imam, should I pray along with him?” He replied, “Yes.” The man asked which of them he should consider his obligatory prayer, and Ibn ‘Umar replied, “Is that your affair?* that is only to be left to God’s decision who will appoint whichever He wishes.” *The Arabic is in the form of a statement, but in view of the phrase immediately following it seems necessary to treat it as a question.Malik transmitted it.

Ibn ‘Umar said, “I prayed along with God’s Messenger two rak'as before and two rak'as after the noon prayer, two after the sunset prayer in his house, and two after the evening prayer in his house.” He said Hafsa told him that God’s Messenger used to pray two short rak'as at daybreak. (Bukhari and Muslim.)

‘A’isha said that the Prophet was more particular about observing the two supererogatory rak'as at dawn than about observing any of the other supererogatory prayers. (Bukhari and Muslim.)

I went to ‘Uqba al-Juhani and said, “I can tell you something about Abu Tamim which will make you wonder. He prays two rak'as before the sunset prayer.” ‘Uqba replied, “We used to do so in the time of God’s Messenger.” I asked, “What prevents you now?” and he replied, “Work.” Bukhari transmitted it.

Ka‘b b. ‘Ujra said that the Prophet came to the mosque of the B. ‘Abd al-Ashhal and prayed the sunset prayer in it. When the people finished their prayer he saw them performing tasbih after it and said, “This is the prayer to be observed at home.”* * This refers to supererogatory prayers. Tasbih is the utterance of 'Glory be to God!’Abu Dawud transmitted it. In the version by Tirmidhi and Nasa’i it says that the people got up and offered supererogatory prayers, whereupon the Prophet said, “Observe this prayer at home.”

Ibn ‘Abbas said that God’s Messenger prolonged the recitation of the Qur’an in the two rak'as after the sunset prayer till the people in the mosque separated. Abu Dawud transmitted it.

‘Ata’ said that when Ibn ‘Umar prayed the Friday noon prayer in Mecca he would go forward and pray two rak'as, then go forward and pray four; but when he was in Medina he prayed the Friday noon prayer, then returned to his house and prayed two rak'as, not praying them in the mosque. Someone mentioned this to him and he replied that God’s Messenger used to do it. Abu Dawud transmitted it. In Tirmidhi’s version he said, “I saw Ibn ‘Umar pray two rak'as after the Friday noon prayer, then he prayed four after that.”

She said that when the Prophet prayed the two rak'as of the dawn prayer he lay down on his right side. (Bukhari and Muslim.)

‘A’isha said that when the Prophet stood up at night to pray he began his prayer with two short rak'as. Muslim transmitted it.

Zaid b. Khalid al-Juhani decided to watch one night what prayers God’s Messenger said. He prayed two short rak'as, then two long, long, long rak'as, then he prayed two rak'as which were less than the two preceding, then he prayed two rak'as which were less then the two preceding, then he prayed two rak'as which were less than the two preceding, then he prayed two rak'as which were less than the two preceding, then he prayed a single one, making a total of thirteen. Muslim transmitted it. The words “then he prayed two rak'as which were less than the two preceding”, mentioned four times, occur thus in Muslim’s Sahih and among those peculiar or him in Humaidi’s book, also in Malik’s Muwatta’, Abu Dawud’s Sunan, and Jami’ al-Usul.

Jubair b. Mut'im reported the Prophet as saying, “You descendants of ‘Abd Manaf must not prevent anyone who goes round this House and prays at any hour of the night or day he wishes.” Tirmidhi, Abu Dawud and Nasa’i transmitted it.

Abfi Huraira said that the Prophet forbade prayer at the middle of the day until the sun declined from the meridian, with the exception of Friday. Shafi‘i transmitted it.

Abu Khalil said on the authority of Abu Qatada that the Prophet disliked prayer in the middle of the day before the sun declined from the meridian, except on Friday, saying, “Jahannam is heated up except on Friday.” Abu Dawud transmitted it, adding that Abu Khalil did not meet Abu Qatada.

He who knows me knows me, and if anyone does not know me, I am Jundub* who heard God's Messenger say, “There is no prayer after the morning prayer till the sun rises, or after the afternoon prayer till the sun sets except in Mecca, except in Mecca, except in Mecca.” * Abu Dharr’s name was Jundub b- Janada.Ahmad and Razin transmitted it.

Abu Huraira reported God’s Messenger as saying, “By Him in whose hand my soul is, I have thought about giving orders for fuel and having it gathered, then giving orders for prayer and having the adhan called for it, then ordering a man to lead the people, then going off to some people (who are not present at the prayer, as it says in a version) and burning down their houses over them. By Him in whose hand my soul is, if one of them knew he would find a fat meaty bone or two fine sheep’s hoofs, he would attend the evening prayer.” Bukhari transmitted it and Muslim has something similar.
