Abu Wa'il narrates from Sayyiduna Abdullah (may Allah be pleased with him) that a man was mentioned in the presence of the Prophet (peace and blessings be upon him): that he stays asleep until morning and does not get up for the prayer. He (peace and blessings be upon him) said: "That is a man in whose ears Satan has urinated," or he said: "in whose ear."
