Musannaf Ibn Abi Shaybah

Hazrat Abu Dharr (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) once said to me, "Look, who appears to you as the most distinguished person in the mosque?" I looked carefully and saw that there was a man in the mosque who was wearing fine clothes. I said, "It is he." Then he asked, "Who appears to you as the most inferior person in the mosque?" I looked and saw that there was a man whose body was covered with worn-out clothes. I said, "It is he." The Prophet said, "If the likes of the first one were to fill the whole earth, this second one is still better than all of them."
