The Prophet ﷺ said, "Perform ablution after eating anything touched by fire."

Its isnad is sahih. Abdul-Malik bin Abu Bakr bin Abdul-Rahman Makhzumi Qurashi has been deemed reliable by scholars, who praised him for his truthfulness, generosity, and eminence, and his hadith is found among the Six Books, having appeared many times before. See the disagreement among the companions in 10792, and see 19592.
