The number of contributions of Muslim civilization brought to humanity and recounted in this book is impressive, and we are surprised by the amount of scientific results attributed to Western or silenced systematically. This book will teach you many things of a civilization that commands admiration and by present time some want to demonize and slander at all costs in order to erase all visible and better stigmatize downsides attributed to him. To bridge the impasse at the school level made on world history and civilization in the period of the Middle Ages, this book reads very well is like a sun that will bring you some light on what the School leaves next to it. Excellent reading to recommend.
