"I almost believe that the Islamic caliphate, as Abu Bakr and Omar understood it, was a bold experiment on the verge of being an adventure, but it did not reach its goal, and it was not possible for it to reach its goal, because it was conducted in an era other than the one in which it could have been conducted, in advance of it." This era is a great precedence. What do you think that humanity has not been able to achieve until now, despite the experiences it has experienced and the advancement it has achieved, and the arts and forms of government it has achieved? Governments must establish a political system in which political and social justice is achieved among people in the way that Abu Bakr and Omar wanted to achieve." Taha Hussein Through this series, we bring to mind the creative and historical works and critical studies of the Dean of Arabic Literature - Dr. Taha Hussein, which made its author a model that we look at with pride and draw inspiration from his experience. We are in dire need for the new generations to read these works, which are presented by the Egyptian Lebanese Publishing House, with a comprehensive translation of them, explanations of some terms, and an introduction to the notables and places mentioned in them, at the hands of an elite group of professors. Each in his field.
