Reacting to the skepticism of some philosophers and unreliable accounts of eschatology Imam Abu Hamid AL Ghazali devoted an entire book to the Sciences of the Beyond according to the Koran and the Sunna. This text was analyzed and translated at the University of Leipzig by the specialist in Semitic studies Lucien Gauthier when Orientalism was abandoning fundamental research to put its utilitarian studies at the service of the triumphant colonial powers. reissue of this translation allows the French speaking reader a better knowledge of Ghazali s work. It can also nourish a reflection on the history of European orientalism the decline of which partly explains the educational deficits deplored by Muslims in Europe.
