Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that the Prophet (peace and blessings be upon him) passed by a dead sheep belonging to a slave-woman of Sayyidah Maymunah (may Allah be pleased with her), and he (peace and blessings be upon him) said: "What harm would there be for these people if they took its skin, tanned it and made use of it?" The people said: "O Messenger of Allah, it is a carcass." He (peace and blessings be upon him) said: "Only eating it has been made unlawful."
