Qutaybah ibn Sa'id and Ahmad ibn 'Abdah al-Dabbi narrated to us, both saying: 'Abd al-'Aziz — namely al-Darawardi — narrated to us from Zayd ibn Aslam, from Humran, the freed slave of 'Uthman, who said: I brought water for ablution to 'Uthman ibn 'Affan, and he performed ablution. Then he said: People are narrating from the Messenger of Allah, peace and blessings be upon him, traditions whose nature I do not know, except that I saw the Messenger of Allah, peace and blessings be upon him, perform ablution like this ablution of mine. Then he said: "Whoever performs ablution in this manner, his previous sins will be forgiven, and his prayer and his walking to the mosque will be an extra reward." In the narration of Ibn 'Abdah: I came to 'Uthman, and he performed ablution.
