Abu Haya bin Qays reported,

I saw Ali perform ablution. He washed his hands until they were clean, then rinsed his mouth three times, drew water into his nose three times, washed his face three times, and washed each of his arms three times. Then he wiped his head, washed his feet up to the ankles, and stood up. He took what was left of his ablution water and drank it while standing. Then he said, "I wanted to show you how the Prophet ﷺ performed ablution."

أخبرنا قتيبة بن سعيد قال حدثنا أبو الأحوص عن أبي إسحق

عن أبي حية وهو ابن قيس قال

رأيت عليا رضي الله عنه توضأ فغسل كفيه حتى أنقاهما ثم تمضمض ثلاثا واستنشق ثلاثا وغسل وجهه ثلاثا وغسل ذراعيه ثلاثا ثلاثا ثم مسح برأسه ثم غسل قدميه إلى الكعبين ثم قام فأخذ فضل طهوره فشرب وهو قائم ثم قال أحببت أن أريكم كيف طهور النبي ﷺ
