In the morning finds semen in his clothes. He (the Imam) said, ‘All praise belongs to Allah who has not left anything without a limit. If he gets up in the morning and looks but does not find anything, he is not required to perform his Salah (prayer) again, but if he gets up and does not look, he is required to perform his Salah (prayer) again.’”
