Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both), describing the Hajj of the Prophet (peace and blessings be upon him), says that on the day of sacrifice the Prophet (peace and blessings be upon him) slaughtered 63 camels himself, and Sayyiduna Ali (may Allah be pleased with him) slaughtered the rest. He had a hundred sacrificial camels. Then a piece of meat was taken from each sacrificial camel, and all of them were cooked together. The Messenger of Allah (peace and blessings be upon him) and Sayyiduna Ali (may Allah be pleased with him) ate of the meat and drank of the broth.
