Abu Dawud
Prayer
Book Number: 002 / Hadith Number: 1029
Narated By Abdullah ibn Buhaynah : The Apostle of Allah (pbuh) led us in prayer praying two rak'ahs. When he stood up and did not sit (at the end of two rak'ahs) the people stood up along with him. When he finished the prayer and we expect him to give the salutation, he said: "Allah is most great." While sitting and made two prostrations before giving the salutation. Then he gave it.
