It was narrated that Ibn 'Abbas (رضي الله عنه) said:

The Messenger of Allah (ﷺ) relieved himself, then he came back and was given a bone with meat on it. He did not do wudoo', but he ate from it. 'Amr added to this hadeeth: It was narrated that Sa'eed bin al-Huwairith said: It was said: O Messenger of Allah, you did not do wudoo’. He said: "I do not intend to pray, such that I would need to do wudoo’.
