Abu Dawud Book 2, Hadith Number 873.
Narated By Hudhayfah : Hudhayfah saw the Apostle of Allah (PBUH) praying at night. He said: Allah is most great” three times, “Possessor of kingdom, grandeur, greatness and majesty.”
He then began (his prayer) and recited Surah al-Baqarah; then he bowed and he paused in bowing as long as he stood up; he said while bowing, “Glory be to my mighty Lord,” “Glory be to my mighty Lord”; then he raised his head, after bowing: then he stood up and he paused as long as he paused in bowing and said, “Praise be to my Lord”; then he prostrated and paused in prostration as long as he paused in the standing position; he said while prostrating: “Glory be to my most high Lord”; then he raised his head after prostration, and sat as long as he prostrated, and said while sitting: “O my Lord forgive me.”
He offered four rak’ahs of prayer and recited in them Surah al-Baqarah, Aal Imran, an-Nisa, al-Ma’idah, or al-An’am. The narrator Shu’bah doubted.
