Abd Khayr reported,

We came to Ali after he had prayed. He called for a jug of water, then rinsed his mouth three times and sniffed water into his nose three times, rinsing his mouth from the same handful with which he sniffed. He washed his face three times, his right hand three times, and his left hand three times. Then he said, "Whoever wishes to know the manner of the Messenger of Allah's ﷺ ablution, this is it."

عن عبد خير قال
