Musaddad narrated that Rib'i bin Abdullah narrated to us; he said that he heard al-Jarud saying: A man of Banu Riyah called Ibn Uthal, who was a poet, came to al-Farazdaq at a watering place on the outskirts of Kufah, on the condition that when the camels came to the water, this one (Ibn Uthal) would slaughter a hundred camels and that one (al-Farazdaq) would slaughter a hundred camels. So when the camels came to the water, the two of them stood up with swords to cut their hamstrings. The people set out on donkeys and mules intending to get the meat. At that time Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) was in Kufah, so he came out riding the white mule of the Messenger of Allah (peace and blessings be upon him), calling out: "O people! Do not eat anything of their meat, for it has been slaughtered in the name of someone other than Allah Almighty."
