'Abdullah bin Ibrahim bin Qariz reported that he found Abu Hurairah (RA) performing ablution in the mosque, who said: I am performing ablution because of having eaten pieces of cheese, for I heard the Messenger of Allah (ﷺ) say: Perform ablution (after eating anything) touched by fire.
'Urwa reported on the authority of'A'isha, the wife of the Messenger of Allah (ﷺ) , saying this: The Messenger of Allah (ﷺ) said. Perform ablution (after eating) anything touched by fire.
