Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Mak'hool that a mouse fell into olive oil, so people asked the Noble Prophet Muhammad (peace and blessings be upon him) about it. He (peace and blessings be upon him) said: "Light lamps with it, but do not eat it." Hazrat Mak'hool used to say that when a mouse falls into ghee and the ghee is solid, then remove the mouse and what is around it and throw it away, and eat the rest. But if the ghee is melted, then none of it should be eaten.
