Musannaf Ibn Abi Shayba 16:543

Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from al-Zuhri, from ‘Ubayd Allah, from Ibn ‘Abbas, from Maymunah, that a sheep belonging to a freedwoman of Maymunah passed by, which had been given to her from the charity, and it had died. He (the Prophet) said: "Why did they not take its hide and tan it, so that they could benefit from it?" They said: "O Messenger of Allah, it is dead (carrion)." He said: "Only its eating has been forbidden."
