Sayyidah Maymunah (may Allah be pleased with her), the wife of the Prophet (peace and blessings be upon him), narrated that some men of Quraysh passed by the Messenger of Allah (peace and blessings be upon him) dragging a sheep of theirs as if it were a donkey. The Prophet (peace and blessings be upon him) said to them: "Why do you not take its skin?" They said: It is carrion. He (peace and blessings be upon him) said: "Water and qaraz purify it."
