Yahya ibn Yahya narrated to us: Abu Khaythamah informed us, from ‘Abd al-Karim, from Mujahid, from ‘Abd al-Rahman ibn Abi Layla, from ‘Ali, who said: The Messenger of Allah, peace and blessings be upon him, commanded me to stand over his sacrificial camels, to give in charity their meat, their hides, and their coverings, and not to give the butcher anything from them. He said: "We give him from our own means."
