Abdur Rahman bin Abi Bakr (may Allah be pleased with him) narrated: He said: Abdur Rahman bin Awf (may Allah be pleased with him) had a silk shirt which he used to wear under his clothes (as an undershirt). Amir Umar (may Allah be pleased with him) said to him: Why do you wear this? So he replied: I have worn this shirt in the presence of a person who was better than you.
