This study is a product of the era of dialogue between religious civilizations in the 15th century AH / 21st AD. I wish we had something like it in the 1st century AH / 7AD, when the conflict between civilizations and wars of conquest spread in full swing. The Arab state faced the two major powers, sweeping away the Persian state and seizing important land from the state. Byzantium took over the political and religious spotlight in a few ten years, allowing us to closely examine the religious map of that time and learn about the development of the Islamic-Christian movement and the reality of religious and social relations under the Islamic political system.
