It was narrated that ‘Aishah said: “Between the time when he finished ‘Isha’ prayer and Fajr, the Prophet used to pray eleven Rak’ahs, saying the Taslimafter 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 lie down on his right side until the Mu ‘adhdhin came to ask permission to say the Iqamah, 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.
