History stands as the most effective and valuable source of putting nation on the course of progress and prosperity and saving them from the path of disgrace and degradation. At a time, when there is tough competition among the nations of the world to excel one another, the Muslim, despite having the most glorious history, appear to be detached and careless as regards their history. This book presents the true Islamic events and their actual causes before the English readers because the other books in the English language found on the Islamic history have been written by such authors and compilers who did no justice in presenting the true picture of Islamic Era but their prejudice prevented them from doing so.
