Nazal bin Sabra reported,

I saw Ali perform the noon prayer, then sit to attend to people's needs. When the time for the afternoon prayer came, a small vessel of water was brought to him. He took a handful from it and wiped his face, his forearms, his head, and his feet, then took what remained and drank it while standing.He said, "Some people dislike doing this, but I saw the Messenger of Allah ﷺ do it. This is the ablution of one who has not broken his ablution."

حدثنا بهز حدثنا شعبة عن عبد الملك بن ميسرة قال سمعت

النزال بن سبرة قال

رأيت عليا رضي الله عنه صلى الظهر ثم قعد لحوائج الناس فلما حضرت العصر أتي بتور من ماء فأخذ منه كفا فمسح وجهه وذراعيه ورأسه ورجليه ثم أخذ فضله فشرب قائما وقال إن ناسا يكرهون هذا وقد رأيت رسول الله ﷺ يفعله وهذا وضوء من لم يحدث
