The following questions have been preoccupying many people for quite sometime.

“Do religious beliefs contradict nationalistic inclination?”

“What were the changes that Islam caused in Iran after its advent in this country? “

“What role did Iranians play in the formation and development of the Islamic civilization?”

This book aims at providing the necessary answers to these questions in three different sections. In the first section the author elaborates on the concepts of Islam and Iranian nationality. The second chapter studies the impact of Islam on the Iranian society as well as the sociological, family, and belief changes this religion brought about in Iran. In the third and final part of the book the author focuses on the services that Iranians rendered to Islam and the role they played in spreading this divine religion and expanding its geographical boundaries to North Africa and China. The author also elaborates on the role of Iranians in the progress of different fields of knowledge (exegesis, philosophy, mysticism, Gnosticism, art, and industry).
