He said that in the year of the Conquest* God's Messenger recited a verse at which a prostration should be made and all the people prostrated themselves. Some were mounted, some were prostrating themselves on the ground, and those who were mounted prostrated themselves on their hands.
‘A’isha said that when God’s Messenger prostrated himself at night when reciting the Qur’an he said, “My face prostrates itself to Him who created it and brought forth its hearing and seeing by His might and power.”
Abu Dawud, Tirmidhi and Nasa’i transmitted it, and Tirmidhi said this is a hasan sahih tradition.
God’s Messenger used to recite the Qur'an to us, and when he came to a place where a prostration should be made he said “God is most great” and prostrated himself, and we prostrated ourselves along with him.
