It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade eating every predatory animal that hunts with canine teeth, and every bird that hunts with its talons, and also forbade consuming the price of carrion, the meat of domesticated donkeys, the earnings of a prostitute, the earnings obtained by mating a bull, and red saddlecloths.
