Musnad Abi Ya'la 499 — he said: I saw Sayyiduna Ali performing

It is narrated from Abu Hayyah (may Allah have mercy on him) that he said: I saw Sayyiduna Ali (may Allah be pleased with him) performing ablution. He washed his hands until he had cleaned them well, then rinsed his mouth three times, put water into his nose three times, washed his face three times, and washed both his arms up to and including the elbows three times. Then he wiped his head and washed both his feet up to the ankles. After that he took the water left over from his ablution and drank it while standing, then said: "I wanted to show you how the ablution of the Messenger of Allah (peace and blessings be upon him) used to be."
