It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once, in the presence of the Messenger of Allah, a man mentioned another person and said, "O Messenger of Allah (peace and blessings be upon him)! So-and-so slept the whole night and did not even offer the Fajr prayer until morning came." The Noble Prophet (peace and blessings be upon him) said, "Satan has urinated in his ear."
