Ali bin Abu Talib reported,

He performed ablution, washing his hands until they were clean, then rinsing his mouth three times and inhaling water into his nose three times. He washed his face three times and his forearms three times, wiped his head once, then washed his feet up to the ankles. Then he stood up, took what was left of his ablution water, and drank it while standing. Then he said, "I wanted to show you how the Messenger of Allah ﷺ performed his ablution."

Sahih

حدثنا هناد وقتيبة قالا حدثنا أبو الأحوص عن أبي إسحق عن أبي حية قال

رأيت عليا

توضأ فغسل كفيه حتى أنقاهما ثم مضمض ثلاثا واستنشق ثلاثا وغسل وجهه ثلاثا وذراعيه ثلاثا ومسح برأسه مرة ثم غسل قدميه إلى الكعبين ثم قام فأخذ فضل طهوره فشربه وهو قائم ثم قال أحببت أن أريكم كيف كان طهور رسول الله ﷺ
