A bomb is any of a range of explosive weapons that only rely on the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy which causes shock waves capable of decapitating human parts and clothes and also causes damages to the ear drum and severe internal bleeding. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. It is a very deadly weapon that causes the irreversible dissintegration of anything it touches. There is no repentance after the blast, unless you are lucky. This is one of the reasons why someone has to be closer to God for protection from the wicked and evil doers.
