[1265] 82 – (389) It was narrated from Abü Hurairah that the Messenger of Allah said: "When one you stands up for prayers, the Sha4ân comes to him and tries to confuse him, until he does not know how many Rak'ah he has prayed. If one of you experiences that, let him prostrate twice while he is sitting."
