Chapter 41: The Book of al-Fara' and al-'Atirah
It was narrated that Ibn 'Abbas said: "The Messenger of Allah passed by a dead sheep that he had given to a freed slave woman of Maimunah, the wife of the Prophet. He said: 'Why don' t you make use of its hide?' They said: 'O Messenger of Allah, it is dead meat.' The Messenger of Allah said: 'It is only forbidden to eat it."
