And Yahya ibn Yahya narrated to us, saying: Muhammad ibn Muslim al-Ta'ifi informed us, from 'Amr ibn Dinar, from Sa'id ibn al-Huwayrith, the freed slave of the family of al-Sa'ib, that he heard 'Abdullah ibn 'Abbas say: The Messenger of Allah, peace and blessings be upon him, went to the toilet. When he returned, food was placed before him, and it was said: "O Messenger of Allah, will you not perform ablution?" He said: "For what? For the prayer?"
