The Necessity of Opining (Using Reason) in Religious Knowledge in the View of Islamic Theology

For a long time the use of and reliance reason and rational thinking in religious sciences has been the subject of speculation in the field of religious thought. in Islam many theological schools not only recognize the validity of reason and rational thinking as a source for acquiring religious knowledge, but also consider the use of reason in this regard as obligatory. Theologians have provided evidence to support their argument. However, there is a controversy among 'Adliyah theologians and Asharites over whether the necessity of opining about judgments is rational or transmitted. Using a theoretical approach, the present paper discusses and evaluates Muslim theologian's arguments for the necessity of adherence to reason in the realm of religious knowledge and its being rational or authoritarian. The research concludes that only one argument about the necessity of opining is correct and the idea of rational necessity of opining has been approved.
