Lady Aisha Siddiqa (may Allah be pleased with her) narrates: The Prophet Muhammad (peace be upon him) used to perform eleven rak'ahs from after the 'Isha prayer, which people call 'Atamah, until Fajr. He would say salam after every two rak'ahs. He would perform Witr with a single rak'ah. When the muezzin would finish giving the adhan for Fajr and the true dawn had appeared and the muezzin would come, he (the Prophet) would get up and perform two short rak'ahs, then he would lie down on his right side until the muezzin would come to call him.
