It is narrated from Hazrat Anas (may Allah be pleased with him) that once Hazrat Zubair (may Allah be pleased with him) and Abdur Rahman bin Awf (may Allah be pleased with him) complained to the Prophet (peace and blessings be upon him) about lice. The Prophet (peace and blessings be upon him) granted them permission to wear silk garments, so I saw each of them wearing a silk shirt.
