Abdullah bin Ibrahim narrates: He found Sayyiduna Abu Hurairah (may Allah be pleased with him) performing ablution on the roof of the mosque. He asked him about this, so Sayyiduna Abu Hurairah (may Allah be pleased with him) informed him that he had eaten pieces of cheese. For this reason, he was performing ablution, because the Noble Prophet (peace and blessings be upon him) said: "Perform ablution after eating something cooked on fire." Imam Abu Hatim (may Allah have mercy on him) states: This narration has been reported by Ibn Qutaybah in the same way, and he mentioned the narrator's name as Abdullah bin Ibrahim, whereas his name is Ibrahim bin Abdullah. (Imam Ibn Hibban (may Allah have mercy on him) says:) Likewise, this narration has been reported to us by Ibn Qutaybah, and he says to us: The narrator's name is Abdullah bin Ibrahim bin Qariz, although his name is Ibrahim bin Abdullah bin Qariz.
