Zar’ah bin Muslim narrates from Sayyiduna Jarhad (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) saw Sayyiduna Jarhad (may Allah be pleased with him) in the mosque, and although he had a sheet over him, his thigh was uncovered. So the Prophet (peace and blessings be upon him) said: The thigh is something that should be covered.
