Musnad Ahmad

Sayyiduna Ali (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) sent me to Yemen. I reached a people who had dug a pit and covered it to hunt a lion (the lion came and fell into it). While they were doing this, suddenly a man fell into the pit, then a second, then a third, until four men fell in. The lion in the pit wounded all of them. Seeing this, a man quickly grabbed a spear and struck the lion, killing it, and all four men also died from their wounds. The heirs of the deceased drew their weapons and stood facing each other for battle. In the meantime, Sayyiduna Ali (may Allah be pleased with him) arrived and said, "The Prophet (peace and blessings be upon him) is still alive; will you engage in mutual killing while he is alive? I will judge between you. If you are satisfied with this, then consider the matter settled, but if you think this does not satisfy you, then you may go to the Prophet (peace and blessings be upon him) and have him decide; he will judge between you, and whoever exceeds the limit after that will not be upon the truth." The decision is that the people of these tribes who participated in digging the pit should collect a quarter blood money, a third blood money, half blood money, and full blood money, and give the heirs of the one who first fell into the pit and was wounded by the lion a quarter blood money, the second a third, and the third a half blood money. They refused to accept this decision (because they did not understand it), so they went to the Prophet (peace and blessings be upon him), who was at Maqam Ibrahim at that time. They narrated the whole story to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said, "I will judge between you," and sat down. In the meantime, a man said, "O Messenger of Allah! Sayyiduna Ali (may Allah be pleased with him) had already judged between us." The Prophet (peace and blessings be upon him) enforced that same decision.
