Uthman called for water and performed ablution. He poured water from his right hand onto his left, then washed both up to the wrists.He then rinsed his mouth and sniffed water into his nose three times, and he mentioned washing each part three times.He wiped his head, then washed his feet, and said, "I saw the Messenger of Allah ﷺ perform ablution just as you have seen me perform it."He then continued with a narration similar to the hadith of Zuhri, and more complete.
