Abstract
The focus of the study examines the areas of human knowledge and its potential in formulating a healthy, scientific image in defending human societies in the face of deviant extremist thought that has spread corruption on the land. It is beautiful to say Ibn Rushd, the Sultan of Andalusia, when he describes the tools of deviation, that ignorance leads to fear, and fear leads To hatred, and hatred leads to violence. This is the equation, and with the agreement of psychologists and sociologists, the human personality crystallizes, its characteristics are known, and its advantages are acquired in the midst of the environment in which he lives. And that the phenomenon of extremism has intellectual agendas and narrow scientific axes and revolves around the methodology of adhering to the fundamentals and leaving the branches on the pretext that it does not possess scientific originality. It is one of the ills of religiosity in previous societies and nations, and it is a rift and division between the members of the same country.
