Musnad Ahmad 12:10

'Arim narrated to us, Mu'tamir ibn Sulayman narrated to us, from his father, from Abu 'Uthman, from 'Abd al-Rahman ibn Abi Bakr, that he said: We were with the Prophet, peace and blessings of Allah be upon him, one hundred and thirty [men]. The Prophet, peace and blessings of Allah be upon him, said: "Does any one of you have food?" It happened that a man had a sa' of food, or something similar. It was kneaded. Then a tall, disheveled polytheist man came with sheep, driving them. The Prophet, peace and blessings of Allah be upon him, said: "Is it a sale or a gift?"—or he said: "Or a donation?" He said: "No, rather a sale." So he bought a sheep from him, and it was prepared. The Prophet of Allah, peace and blessings of Allah be upon him, ordered that the liver (lit. black of the belly) be roasted. He said: By Allah, there was not one of the one hundred and thirty but that the Messenger of Allah, peace and blessings of Allah be upon him, cut a piece for him from its liver. If he was present, he gave it to him, and if he was absent, he saved it for him. He said: He made two large bowls from it. He said: So we all ate and were satisfied, and there remained [some] in the two bowls, so we carried it on a camel, or as he said.
