There are 10 forbidden types of food mentioned in Allah’s book. Allah says: ‘Forbidden to you are carrion, blood, the flesh of swine; and that over which any name other than Allah’s has been invoked; and the animal that has been strangled, or beaten to death, or killed by a fall, or gored to death, or savaged by a beast of prey, except that which you may have slaughtered when it is still alive, and [forbidden to you are] animals that have been slaughtered on idolatrous altars’ (5: 3).
