Mukhtasar Bukhari

Umm al-Mu’minin Aisha Siddiqa (may Allah be pleased with her) says that the Messenger of Allah (peace and blessings be upon him) used to pray eleven rak’ahs, that is, this was his (peace and blessings be upon him) tahajjud prayer. In it, his prostration was so (long) that any one of you could recite fifty verses before he (peace and blessings be upon him) would raise his head. And he (peace and blessings be upon him) used to pray two rak’ahs before the Fajr prayer, then he would lie on his right side until the muezzin would come to him (peace and blessings be upon him) to inform him of the prayer.
