In Reason and Revelation in Islam, Ahmed Oulddali presents the psychological and epistemological ideas which underlie Faḫr al-DÄ«n al-RÄzÄ«âs speculative exegesis. Known as one of the few Muslim theologians to have proposed a philosophical interpretation of the QurʾÄn, RÄzÄ« appears here as an innovative thinker, deeply convinced of the need to rely on rational methods to understand revelation. His formal rejection of literalism and his multiple borrowings from Avicennaâs philosophy are explained as a consequence of a conception of knowledge in which reason plays a decisive role. Richly infused with illustrative texts and original translations from Arab sources, Oulddaliâs book offers an overview of the philosophical, theological and exegetical issues to which the thinking of RÄzÄ« responds.
