This book was prepared by a group of Saudi scholars and intellectuals. They address Western mind which looks at fair truth and objective and convincing dialogue. The book, in general, discusses the most important issues and suspicions raised by Western political and media organizations in the aftermath of September 11, 2001 events. These events have placed Islam, the Kingdom, its people, and its religious, educational and social institutions in a position that requires correction and review. The book is a moderate vision in responding to the issues and suspicions. A biased reader would notice the major difference between the reality and the raised concepts and images which were far from the reality.
