Sahih Muslim, 539

Humran, the freed slave of 'Uthman said:I saw Uthman call for a vessel (of water) and poured water over his hands three times and then washed them. Then he put his right hand in the vessel and rinsed his mouth and cleaned his nose. Then he washed his face three times and his hands up to the elbow three times; then wiped his head, then washed his feet three times. Then he said that the Messenger of Allah (ﷺ) had said: He who performed ablution like this ablution of mine and offered two raka`ahs of prayer without allowing his thoughts to be distracted, all his previous sins would be expiated

Rapporté par Humran, l’affranchi de ‘Uthman رضي الله عنه : J’ai vu ‘Uthman demander un récipient d’eau, verser de l’eau sur ses mains trois fois et les laver. Puis il a plongé sa main droite dans le récipient, s’est rincé la bouche et a nettoyé son nez. Ensuite, il a lavé son visage trois fois, ses mains jusqu’aux coudes trois fois, puis il a essuyé sa tête, puis il a lavé ses pieds trois fois. Ensuite, il a dit que le Messager d’Allah ﷺ avait dit : « Celui qui fait ses ablutions comme je viens de le faire et prie deux unités sans se laisser distraire, tous ses péchés passés seront pardonnés. »
