This book reveals the theories that inspire al-Qaeda. There is no other accessible book on the subject. This is the sect that threatens the stability of Saudi Arabia and the Middle East. Wahhabism has been generating controversy since it first emerged in Arabia in the 18th century. In the wake of September 11th instant theories have emerged that try to root Osama Bin Laden's attacks on Wahhabism. Muslim critics have dismissed this conservative interpretation of Islam that is the official creed of Saudi Arabia as an unorthodox innovation that manipulated a suggestible people to gain political influence. David Commins' book questions this assumption. He examines the debate on the nature of Wahhabism, and offers original findings on its ascendance in Saudi Arabia and spread throughout other parts of the Muslim world such as Afghanistan and Pakistan.
