Note 21 — Chapter III · THE SPREAD OF ISLAM AMONG THE CHRISTIAN NATIONS OF WESTERN ASIA.

Due provision was made for the instruction of the new converts, for while whole tribes were being converted to the faith with such rapidity, it was necessary to take precautions against errors, both in respect of creed and ritual, such as might naturally be feared in the case of ill-instructed converts. Accordingly we find that the caliph ʻUmar appointed teachers in every country, whose duty it was to instruct the people in the teachings of the Qurʼān and the observances of their new faith. The magistrates were also ordered to see that all, whether old or young, were regular in their attendance at public prayer, especially on Fridays and in the month of Ramaḍān. The importance attached to this work of instructing the new converts may be judged from the fact that in the city of Kūfah it was no less a personage than the state treasurer who was entrusted with this task.21
