The description of Uthman (may Allah be pleased with him)

Sayyiduna Usamah bin Zayd (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) sent me to Sayyiduna Uthman (may Allah be pleased with him) with a bowl which had meat in it. When I came to his house, Sayyidah Ruqayyah (may Allah be pleased with her) was sitting there. I have never seen a more beautiful couple than the two of them. Sometimes I would look at Sayyidah Ruqayyah (may Allah be pleased with her) and sometimes I would look at Sayyiduna Uthman (may Allah be pleased with him). When I returned, the Prophet (peace and blessings be upon him) asked me: Did you go to them? I replied: Yes! The Prophet (peace and blessings be upon him) asked: Have you ever seen a more beautiful couple than the two of them? I said: No, O Messenger of Allah! I too would sometimes look at Sayyidah Ruqayyah (may Allah be pleased with her) and sometimes at Sayyiduna Uthman (may Allah be pleased with him).

Al-Hasan bin Abi al-Hasan narrates: I entered the mosque and there before me was Sayyiduna Uthman (may Allah be pleased with him), reclining on his upper sheet. Two water-carriers came to him and presented their dispute to Sayyiduna Uthman (may Allah be pleased with him), and Sayyiduna Uthman (may Allah be pleased with him) gave judgment between them. Then I went to Sayyiduna Uthman (may Allah be pleased with him) and looked at him closely: he was a man with a handsome face. On his face were some marks of smallpox, and his hair covered his forearms.
