He heard Ibn 'Abbas (رضي الله عنه) and saw Abu Hurairah (رضي الله عنه) doing wudoo’. He said: Do you know because of what I am doing wudoo’. He said: No. He said: I am doing wudoo’ because I ate some pieces of dried yoghurt. Ibn 'Abbas said: I do not care because of what you are doing wudoo’. I bear witness that I saw the Messenger of Allah (ﷺ) eat a shoulder of meat, then he got up to pray and did not do wudoo'.
