He witnessed Ali perform the noon prayer, then sit in the open courtyard attending to people's needs. When the time for the afternoon prayer came, a vessel of water was brought to him. He took a handful of water and wiped his hands, forearms, face, head, and feet, then drank what was left of it while standing.He then said, "Some people dislike drinking while standing, but the Messenger of Allah ﷺ did exactly as I have done. This is the ablution of one who has not broken his ritual purity."
حدثنا محمد بن جعفر حدثنا شعبة عن عبد الملك بن ميسرة
أنه شهد عليا رضي الله عنه صلى الظهر ثم جلس في الرحبة في حوائج الناس فلما حضرت العصر أتي بتور فأخذ حفنة ماء فمسح يديه وذراعيه ووجهه ورأسه ورجليه ثم شرب فضله وهو قائم ثم قال إن ناسا يكرهون أن يشربوا وهم قيام وإن رسول الله ﷺ صنع كما صنعت وهذا وضوء من لم يحدث
