Abdullah bin Ibrahim Zahri narrated, he saw Hazrat Abu Hurairah (may Allah be pleased with him) performing ablution on the roof of the mosque, so Abu Hurairah (may Allah be pleased with him) said: I performed ablution because I ate a piece of cheese, and I heard the Messenger of Allah (peace and blessings be upon him) saying, "Perform ablution after eating something cooked on fire."
