It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, was asked about a mouse that falls into clarified butter (ghee) and dies. He, peace and blessings be upon him, said: "If the ghee is solid, then remove the mouse and the ghee around it, and if it is liquid, then do not use it for eating."

Abu Zubair (may Allah have mercy on him) says: I asked Sayyiduna Jabir (may Allah be pleased with them both) whether I could eat food or drink in which a mouse has fallen. He said: "No, the Messenger of Allah (peace and blessings be upon him) forbade it." We used to keep ghee in pots, and the Prophet (peace and blessings be upon him) said: "When a mouse dies in such a vessel, do not eat from it."

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the wife of the Messenger, Sayyidah Maymunah (may Allah be pleased with her), reports: A mouse fell into solidified ghee and died. When the Messenger of Allah (peace and blessings be upon him) was asked about it, he said: "Remove it and the ghee around it, throw them away, and eat the rest."
