Ibn Numayr narrated to us, my father narrated to us, Hanzalah narrated to us, from al-Qasim ibn Muhammad, who said: I heard 'A'ishah say: The Messenger of Allah (peace be upon him) used to pray ten rak'ahs at night, and he would observe the witr with one prostration, and he would pray the two rak'ahs of the dawn (fajr). That made thirteen rak'ahs.
