The people of Ḥīrah had likewise resisted all the efforts made by Khālid to induce them to accept the Muslim faith. This city was one of the most illustrious in the annals of Arabia, and to the mind of the impetuous hero of Islam it seemed that an appeal to their Arab blood would be enough to induce them to enrol themselves with the followers of the Prophet of Arabia. When the besieged citizens sent an embassy to the Muslim general to arrange the terms of the capitulation of their city, Khālid asked them, “Who are you? are you Arabs or Persians?” Then ʻAdī, the spokesman of the deputation, replied, “Nay, we are pure-blooded Arabs, while others among us are naturalised Arabs.” Kh. “Had you been what you say you are, you would not have opposed us or hated our cause.” ʻA. “Our pure Arab speech is the proof of what I say.” Kh. “You speak truly. Now choose you one of these three things: either (1) accept our faith, then your rights and obligations will be the same as ours, whether you choose to go into another country or stay in your own land; or (2) pay jizyah; or (3) war and battle. Verily, by God! I have come to you with a people who are more desirous of death than you are of life.” ʻA. “Nay, we will pay you jizyah.” Kh. “Ill-luck to you! Unbelief is a pathless desert and foolish is the Arab who, when two guides meet him wandering therein—the one an Arab and the other not—leaves the first and accepts the guidance of the foreigner.” [64] 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.
