Abstract

Over many centuries of Islamic history, there were individuals and trends of thought that introduced their own deviated deductions as authentic and revolutionary Islam by adopting a radical policy. They made some ignorant people to follow them. In this regard, two excommunicating trends of thought named Al-Qaeda and the Khawarij of Iraq are related to the area of these extremist trends for having common intellectual - practical indicators. Unlike the masses of religious scholars, these two political-military trends had put efforts to combat Muslim rulers. They picked the preliminary reading of religion and exerted violent behaviors under name of Islam. Based on this deduction, they have represented the most radical and violent system of thought. In this regard, by comprising these two Islamist trends, the authors infer that the violence and quarrel some of these trends originate in their ignorance and the lack of knowledge of the different affaires related to themselves, to Islamic teachings, and to culture predominating over Islamic societies. These attitudes have been manifested as various forms of prejudice, excommunication, extremism, etc. By offering a fale interpretation of the facts, they have created an atmosphere of discrepancy, disunion and massacre in the Islamic societies.
