Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: I went in to Sayyidah Ruqayyah (may Allah be pleased with her), the daughter of the Messenger of Allah (peace and blessings be upon him) and the wife of Uthman (may Allah be pleased with him), and she had a comb in her hand. She said: The Messenger of Allah (peace and blessings be upon him) has just left me; I combed his hair. He (peace and blessings be upon him) said: "How do you find Abu Abdullah (Uthman)?" I said: "Good." He (peace and blessings be upon him) said: "Honour him, for he is among those of my Companions most similar to me in character."
