مسند أحمد

It was narrated from ‘Ali (رضي الله عنه) that He called for a jug of water, then he said: Where are those who say that they dislike drinking whilst standing? He took it and drank whilst standing then he did a light wudoo` and wiped over his shoes, then he said: This is the wudoo’ of the Messenger of Allah (ﷺ) for one who is pure and has not broken his wudoo’.
