Moreover the Abbasid Caliphate witnessed a wide intellectual growth due to various reasons. They include the Abbasids' new policy that aims at setting the foundations of intellectual freedom, the geographical extent that the territory saw, which has multiple intellectual and political environments, the conversion of various groups of people from diverse backgrounds and cultures to Islam, the act of translation that leads to an intellectual open-mindedness towards the philosophy and languages of other nations and the Islamic intellectual movement that contributes in emerging Islamic doctrines and sects. All of these lead to intellectual theses that could impact the intellectual structure of Islam. As a result, a scientific religious intellectual reference became a must that is able to cope with all these intellectual parameters in order to maintain the Islamic identity.
