Chapter 41: The Mu'adhdhins Notifying The Imams Of The Prayer
"Between the time when he finished 'Isha' prayer and Fajr, the Prophet (S.A.W) used to pray eleven Rak'ahs, saying the Taslim after each two Rak'ahs, then praying Witr as one Rak'ah. He would prostrate for as long as it takes one of you to recite fifty verses, then he would raise his head. When the Mu'adhdhin finished the call to Fajr prayer and he could see the dawn, he would pray two brief Rak'ahs, then he would go out with him." Some of these narrators (Ibn Abi Dhi'b, Yunus and 'Amr bin Al-Harith) added some phrases not mentioned by the others in the Hadith.
"I asked Ibn 'Abbas: 'How did the Messenger of Allah (S.A.W) pray at night?' He said: 'He prayed eleven Rak'ahs including Witr, then he slept deeply until I could hear him snoring, then Bilal came to him and said: "The prayer, O Messenger of Allah!" Then he got up and prayed two brief Rak'ahs then led the people in prayer, and he did not perform Wudu'.'"
Chapter 42: The Mu'adhdhin Saying The Iqamah When The Imam Comes Out
"The Messenger of Allah (S.A.W) said: 'When the Iqamah for prayer is said, do not stand up until you see that I have come out.'"
