Musannaf Ibn Abi Shayba 13:1698

Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Hisham bin Sa’d narrated to us, from ‘Amr bin Shu’ayb, from his father, from his grandfather, that a man asked the Prophet, peace and blessings of Allah be upon him, about a stray sheep. He said: "It is for you, or for your brother, or for the wolf." And he asked him about a stray camel. He said: "What do you want with it? It has its water skin and its shoes; it eats the pasture and goes to the water."
