Sa'd bin Mas'ud al-Kindi (may Allah have mercy on him) narrates: Uthman bin Maz'un (may Allah be pleased with him) came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, I feel shy that my family should see my private parts. He (peace and blessings be upon him) said: "Why? When Allah has made you a garment for them and made them a garment for you." He said: I dislike it. He (peace and blessings be upon him) said: "They see it from me, and I also see it from them." He said: But you are the Messenger of Allah. He (peace and blessings be upon him) said: "I (indeed do so)." He said: You (do so)? Then who after you (can avoid it)? The narrator said: When Uthman turned away, the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Uthman bin Maz'un is very shy and fond of covering."
