English Translation

Yahya told us, from Hisham, from Yahya, from Iyad, that he asked Abu Sa'id al-Khudri, saying, "One of us prays and does not know how much he has prayed." He said: The Messenger of Allah, peace and blessings be upon him, said, "When one of you prays and does not know how much he has prayed, let him prostrate two prostrations. If Satan comes to him and says, 'You have invalidated your prayer,' let him say, 'You lie,' unless he finds a smell with his nose or a sound with his ear." Suwayd ibn Amr told us: Aban told us: Yahya told us, from Hilal ibn Iyad, from Abu Sa'id al-Khudri, that the Messenger of Allah, peace and blessings be upon him, said, "When one of you prays..." and he mentioned its like. [The compiler] said: Yunus told us: Aban told us, from Yahya, from Hilal ibn Iyad; and Abdur-Razzaq told us: Ma'mar told us, from Yahya, who said: Iyad ibn Hilal informed me that he heard Abu Sa'id, and he mentioned its like.
