It is narrated from Abdullah bin Qariz that he found Hazrat Abu Hurairah (may Allah be pleased with him) performing ablution on the roof of the mosque. Abu Hurairah (may Allah be pleased with him) said: I am performing ablution because I have eaten pieces of cheese. Indeed, the Messenger of Allah (peace and blessings be upon him) said: "Perform ablution after eating something cooked on fire."
