Abu Dawud
Prayer
Book Number: 002 / Hadith Number: 1350
Narated By Fadl b. 'Abbas : I spent a night with the Prophet (pbuh) to see how he prayed. He got up, performed ablution and prayed two rak'ahs. His standing was like his bowing (i.e. equal duration)., and his bowing was like his prostration (equal in length). Then he slept. Afterwards he awoke, performed ablution, and used tooth-stick. He then recited five verses from Sura 'Al-Imran.; In the creation of the heavens and the earth and the alternations of the night and day. He went on doing so till he prayed ten rak'ahs. He then stood up and prayed one rak'ah observing witr in it. In the meantime the mu'adhdhdin called to prayer. The Apostle of Allah (pbuh) stood up after the mu'adhdhdin had kept silent. He prayed two light rak'ahs and remained silent till he offered the dawn prayer.
Abu Dawud said: A part of the tradition transmitted by Ibn Bashshar remained hidden from me.
