It's been almost ten years since I left the Muslim faith. I stopped believing in Islam after I'd made a serious study of the seemingly bottomless well of the Islamic sacred texts, a long and difficult task that required not only that I work on the commandments of my former masters (the God Allah and His prophet Muhammad), but also that I work on myself. It led me to glimpse conclusions and consider concepts that until then I'd never heard or seen elsewhere.Here, in France, Islamic scholars talk about feelings, motivations, intentions and aims. In this way, they all draw the conclusions that the Koran is not a source of problems and that the Islam of the prophet Muhammad is a religion of peace, love and tolerance. But do you know of a single global (and systemic) survey of the sacred texts of Islam that gives a critical overview of the Koranic dogmas and analyzes their limits without falling into moralizing or the Manichean concepts of Good and Evil ? It's because I've never found one that I decided to set myself the challenge of making the work I'd always wanted available to the whole world. This book, in your hands, is a different way that I suggest, a new method to win the battle of the ideas against a totalitarism without borders nor uniforms, and that we simply call � religion � in our Western World.
