Bulugh al-Maram 33
Narrated Humran, the manumitted slave of Uthman:
Uthman (rad) called for water to perform ablution. He washed palms of his hands three times, then rinsed his mouth and sniffed water in his nose and then blew it out. He then washed his face three times. Thereafter he washed his right hand up to his elbow three times, then the left one likewise, then he passed wet hands on his head. Then he washed his right foot up to the ankle three times, then the left one likewise. He then said, “I saw Allah’s Messenger (ﷺ) performing ablution like this ablution of mine”. [Agreed upon]
