(Second chain) There is a narration of the same kind, except that in it is: So the Prophet (peace and blessings be upon him) bent his foot, faced the Qiblah, and performed two prostrations, then turned towards us and said: If anything new had been prescribed in the prayer, I would certainly have informed you. The fact is that I am only a human being; I forget just as you forget. So if I forget, remind me. And if any one of you is uncertain in his prayer, he should seek the situation that is closest to correctness, then complete his prayer and after saying the salam, perform two prostrations.
