This book provides a critical history of Wahhabism - the extreme form of so called Islamic ideology that originated from Najd, Saudi Arabia. The author deals with the topic in detail as how the founder of this ideology was influenced by deviant thoughts, lacked academic knowledge of Islamic fiqh and other necessary sciences. The Wahhabi history is filled with massacres of innocent Muslims in the name of shirk (polytheism) and bida (innovation in religion).
