Prayer (Kitab Al-Salat): Details of Commencing Prayer
Dawud :: Book 3 : Hadith 872
Narrated Awf ibn Malik al-Ashja'i:
I stood up to pray along with the Apostle of Allah (peace_be_upon_him); he got up and recited Surat al-Baqarah (Surah 2).
When he came to a verse which spoke of mercy, he stopped and made supplication, and when he came to verse which spoke of punishment, he stopped and sought refuge in Allah, then he bowed and paused as long as he stood (reciting Surah al-Baqarah), and said while bowing, "Glory be to the Possessor of greatness, the Kingdom, grandeur and majesty."
:Then he prostrated himself and paused as long as he stood up and recited Surat Aal Imran (Surah 3) and then recited many surahs one after another.
