مسند أحمد

It was narrated that Abu Hayyah said: I saw ‘Ali (رضي الله عنه) doing wudoo`. He washed his hands until they were clean, then he rinsed his mouth three times, then he rinsed his nose three times; he washed his face three times and his forearms three times; he wiped his head and washed his feet up to the ankles. And he took the leftover water and drank it whilst standing. Then he said: I wanted to show you how the Messenger of Allah (ﷺ) did wudoo` ‘Abd Khair narrated a hadeeth like that of Abu Hayyah from `Ali, except that ’Abd Khair said: When he finished his wudoo’, he took some of the leftover water in his hand and drank it.
