Fath al-Rabbani

Abd Khair (may Allah have mercy on him) says: We performed the Fajr prayer and came to Syedna Ali (may Allah be pleased with him) and sat with him. He asked for water for ablution, so a vessel was brought in which there was water and a basin was brought. Then he poured water on his right hand and washed both hands three times. Then he rinsed his mouth three times and put water into his nose three times, one handful at a time. In another narration, it is mentioned: He rinsed his mouth three times with one handful and put water into his nose three times. Then he washed his face three times and washed his arms three times. Then he put his hand into the vessel and wiped his head once with both palms. Then he washed his feet three times each and then said: "This is the ablution of your Prophet, so learn it."
