The slaughter can be performed by a Muslim or an adherent of religions traditionally known as People of the Book (Jews, Christians and Sabians). Blood must be drained from the veins. Carrion (carcasses of dead animals, such as animals who died in the wild) cannot be eaten. Additionally, an animal that has been strangled, beaten (to death), killed by a fall, gored (to death), savaged by a beast of prey (unless finished off by a human), or sacrificed on a stone altar cannot be eaten.
