Musnad Ahmad 5:12

Abu Sa’id narrated to us, Isra’il narrated to us, Simak narrated to us, from Hanash, from ‘Ali, who said: The Messenger of Allah (ﷺ) sent me to Yemen. We arrived at a people who had built a pit for a lion. While they were pushing one another, a man fell in, and he clung to another, then a man clung to another, until four of them were in it. The lion wounded them, then a man stood up to it with a spear and killed it, and they all died from their wounds. The guardians of the first man rose up against the guardians of the others, and they drew weapons to fight one another. ‘Ali (may Allah be pleased with him) came to them at that juncture and said: "Do you wish to fight while the Messenger of Allah (ﷺ) is alive? I will judge between you with a judgment; if you are satisfied with it, then it is the judgment, otherwise I will restrain some of you from others until you come to the Prophet (ﷺ) and he is the one who judges between you. Whoever transgresses after that, he has no right." "Collect from the tribes of those who were present at the pit a quarter of the blood money, a third of the blood money, half of the blood money, and the full blood money. For the first is a quarter, because those above him perished; for the second is a third of the blood money; for the third is half of the blood money." They refused to be satisfied, so they came to the Prophet (ﷺ) while he was at the Station of Ibrahim, and they narrated the story to him. He said: "I will judge between you," and he sat with his legs drawn up to his abdomen. A man from the people said: "Indeed, ‘Ali judged among us," and they narrated the story to him, and the Messenger of Allah (ﷺ) approved it.
