In the Koran, there isn't one mention of attaching explosives to one's body and detonating in a crowded area. Possibly,this is due to the fact that gunpowder didn't exist in 500AD, or that the Koran preaches peace. In that year, the only possible way of selfexploding was to gorge oneself on badly cooked camel and dates. There wasn't any Bromo then,either.
