It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both), he says: Sayyiduna Ali (may Allah be pleased with him) entered my house and asked for water for ablution, and we brought a small vessel in which there was about one mudd of water, until the vessel was placed before him, while he had also relieved himself. He said: "O Ibn Abbas! Shall I not perform for you the ablution of the Messenger of Allah (peace and blessings be upon him)?" I said: "Yes, why not, may my parents be sacrificed for you." So the vessel was placed for him, he washed his hands and rinsed his mouth, drew water into his nose and blew it out, then took water with both hands and wiped it over his face and put his thumbs in the front part of his ears, then repeated this action three times, then took a handful of water with his right hand and poured it over the front part of his head and it flowed over his face, then washed his right hand up to and including the elbow three times, then washed the other hand in the same way, then wiped over his head and the outer part of his ears, then took water with both palms and wiped it over his feet while he was wearing shoes, then turned his foot over, then did the same with the other foot. I said: "Ablution with shoes on?" He said: "Yes, with shoes on." I said: "With shoes on?" He said: "Yes, with shoes on." I said: "With shoes on?" He said: "Yes, with shoes on."
