‘A’isha said that between the time when he finished the evening prayer and the dawn prayer the Prophet used to pray eleven rak'as, uttering the salutation at the end of every two and observing the witr,* with a single one, and during that he would make a prostration about as long as one of you would take to recite fifty verses before raising his head. When the mu’adhdhin finished making the call for the dawn prayer and he saw the dawn clearly, he stood up and prayed two short rak'as, then lay down on his right side till the mu’adhdhin came to him for the iqama, whereupon he would go out. *Cf. chap. 36 (Bukhari and Muslim.)
