Sunan al-Nasa'i — The Book of Purification

“I saw ‘Ali (may Allah be please with him) praying Zuhr, then he sat to tend to the people’s needs, and when the time for ‘Asr came, a vessel of water was brought to him. He took a handful of it and wiped his face, forearms, head and feet with it, then he took what was left and drank standing up. He said: ‘People dislike this, but I saw the Messenger of Allah (ﷺ) doing it. This is the Wudu’ of one who has not committed Hadath.”

The Prophet (ﷺ) forbade that a man should drink while standing.

he gave a horse called Ghamr or Ghamrah to someone, then he saw one of its colts or fillies attributed to his horse being sold, but he refrained from (buging) it.
