Who was Muhammad ibn Abdul Wahhab and what was his mission? Is Wahhabiyyah a new, misguided sect? Was 'Wahhabiyyah' a reformist movement or a new creed intent on destroying Islam? The answers to these and many other questions can be found in a new, extensively researched biography and explanation of Muhammad Ibn Abdul Wahhab's mission. This is an important research that contains quotes from many Western and Eastern writers and historians about a movement that presently evokes a variety of emotions in those who hear about it.
