It is narrated from Hazrat Aisha that the Prophet (peace be upon him) used to pray eleven rak'ahs between Isha and Fajr, saying salam after every two rak'ahs and performing one rak'ah of 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 would come and inform the Prophet (peace be upon him) about the prayer.
