The starting point of the present study is the clash between the warrior instinct inherent in human nature and Islamic law, the realistic character of which is unanimously acknowledged.
Islam, in fact, cannot tolerate excessive displays of this instinct, which, as Professor Muhammad Taha Badawi points out, is the strongest of all the impulses to which man is inclined. Inseparably linked to all the factors inciting man to make war, and itself at times unleashing war, the warrior instinct, in any case, arouses violence and becomes a reflex action in anyone subjected to the danger of death.
