A Study on the Arrival of Islam in Iran

A survey on why and how Muslims entered Iran and how Islam spread relatively fast throughout this country during the first centuries after Hejira is among subjects with which the researchers are still concerned. Being aware of political and religious conditions in Iran on the eve of the arrival of Muslim Arabs, the moods and thoughts of the Muslim army as opposed to the Iranian army, and more importantly, the attractions and merits of Islam as opposed to the distorted Zoroastrianism would lead us to understand the reasons why Iranians abandoned the old Zoroastrianism and converted to Islam. The present article uses a theoretical and analytical approach in investigating the manner of and reason for arrival of Islam in Iran.
