Global peace and security can be established and guaranteed through peaceful coexistence of all nations. All heavenly religions and divine prophets promote monotheism, call to peace and security, urge respect for the followers of all religions, and in this way, try for the salvation of humanity. With the passing of time, as the distance between the founding fathers of religion and the believers in that region gradually grows, slight deviations begin to appear. One important deviation we have witnessed in the history of religions is the growth of dogmatism as the result of which some people overlook the principle of peaceful coexistence. Historically speaking, some Jews and Christians fell in the pitfall. They ended up in a disastrous racism that ignited bloody wars with thousands of victims and casualties. The history of Jewish racism is darker. Not only did some Jews believe they were chosen by God exclusively as the elected nation, but they also demanded the subordination of other nations to them. Racial discrimination in contrast with human rights dates back to far past. Since its advent, Islam struggled against this tendency. Declaring peaceful coexistence of all followers of religions as a principal value, Islam issued its human charter 14 centuries ago stressing the common grounds among people of different faiths. The political and social life of the holy Prophet and His Immaculate Successors indicate that tolerance, moderation, and gentleness are the three leading principles in interaction with people.
