It is narrated from Hazrat Aisha (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) used to pray eleven rak'ahs between Isha and Fajr, saying salam after every two rak'ahs. He would pray one rak'ah as Witr. In the nawafil, he would perform such a long prostration that before he raised his head, any one of you could recite fifty verses. When the muezzin finished giving the first adhan, he would pray two short rak'ahs, then lie down on his right side until the muezzin would come and inform the Prophet (peace and blessings be upon him) that the prayer was about to begin.
