This book, the result of 30 years spent by the author in exhaustive research, attempts to present the basic teachings of religion in the light of modern knowledge and in a manner consistent with modern scientific method. After a thorough investigation of the subject, the writer has reached the conclusion that religious teachings are, academically, valid and as understandable and intellectually acceptable as any of the theories propounded by men of science. “…in the fourteen hundred years of Islamic history, innumerable books on Islam have appeared. There are just a few books calling mankind to God which are clearly distinguishable from the rest because of the clarity and force with which they make their appeal. Without doubt, this book is one of that kind.” –AL-AHRAM, (Cairo)
