International Humanitarian Law is a body of laws enacted in the four conventions of Geneva in 1949 and the two annexed protocols in 1977 but they can be found in fundamental principles of religions, Islam in particular.More than 14 centuries earlier, Prophet Muhammad verbally and indirectly forbade the following actions during war: killing civilians, mutilation, killing the enemy's emissary, using mass destruction weapons, betrayal and perfidy, and torturing and killing the captives. Adducing the Prophet's way of life and other evidence, jurists deem these actions illegal.
