What did the Prophet Muhammad (peace be upon him) do during his night prayer?
 Narrated `Aisha:                     Allah's Apostle used to pray eleven rak`at at night and that was his night prayer and each of his prostrations lasted for a period enough for one of you to recite fifty verses before Allah's Apostle raised his head. He also used to pray two rak`at (Sunna) before the (compulsory) Fajr prayer and then lie down on his right side till the Mu'adh-dhin came to him for the prayer.
