Two teams of researchers in the Islamic Seminary School in Qum began investigating the roots of the evil and wicked phenomena of terrorism and Takfīrīsm. After much research it was proven through conclusive evidence that Takfīrīsm and other similar extremist ideologies have been born out of the Wahhabi ideology which has been developed and promoted by Saudi Arabia. The book in question has been published in the Farsi language and is currently being translated in to Arabic, English, and Urdu in order to be made available to all the people of the world.
