Producing and Using Weapons of Mass Destruction according to Islamic Jurisprudence

The present writing aims to prove that, according to [Islamic] jurisprudence and Ijtihad, producing and using weapons of mass destruction (atomic, microbial, and nuclear) are prohibited. By weapons of mass destruction, weapons are meant which have an extraordinary destruction power and, in addition to military people, kill civilians. Based on rational arguments, some Quranic verses as well as noble hadiths, it has been argued that even if the enemy has such weapons and uses them, Islam does not allow to use these weapons in war. In the present article, it has been clearly explained that Islam never agrees that Muslims do whatever action against enemies and disbelievers in war. For example, if disbelievers kill Muslim prisoners or mutilate them, Islam never does allow Muslims to do similar actions.
