But if this doctrine grew up early in Islam, opposition to it was not slow in appearing, and that on different sides. Literary vanity, national pride, and philosophical scruples all made themselves felt. Even in Muhammad’s lifetime, according to the legend of the poet Labid and the verses which he put up in challenge on the Ka‘ba, the Qur’an had taken rank as inimitable poetry. At all points it was the Word of God and perfect in every detail. But, among the Arabs, a jealous and vain people, if there was one thing on which each was more jealous and vain than another, it was skill in working with words. The superiority of Muhammad as a Prophet of God they might endure, though often with a bad grace; but Muhammad as a rival and unapproachable literary artist they could not away with. So we find satire of the weaknesses of the Qur’an appearing here and there, and it came to be a sign of emancipation and freedom from prejudice to examine it in detail and balance it against other products of the Arab genius. The rival productions of Musaylima, the False Prophet, long enjoyed a semi-contraband existence, and Abu Ubayda (d. 208) found it necessary to write a treatise in defence of the metaphors of the Qur’an. Among the Persians this was still more the case. To them, Muhammad might be a prophet, but he was also an Arab; and while they accepted his mission, accepting his books in a literary way was too much for them. As a prophet, he was a man; as a literary artist, he was an Arab. So Jahm ibn Safwan may have felt; so, certainly, others felt later. The poet Bashshar ibn Burd (killed for satire, in 167), a companion of Wasil ibn Ata and a Persian of very dubious orthodoxy, used to amuse himself by comparing poems by himself and others with passages in the Qur’an, to the disadvantage of the latter. And Ibn al-Muqaffa (killed about 140), the translator of “Kalila and Dimna” and many other books into Arabic, and a Persian nationalist, is said to have planned an imitation of the Qur’an. [Sidenote: MU‘TAZILITE ATTITUDE] Added to all this came the influence of the Mu‘tazilite theologians. They had a double ground for their opposition. The doctrine of an absolutely divine and perfect book limited them too much in their intellectual freedom. They were willing to respect and use the Qur’an, but not to accept its _ipsissima verba_. Regarded as the production of Muhammad under divine influence, it could have a human and a divine side, and things which needed to be dropped or changed in it could be ascribed to the human side. But that was not possible with a miraculous book come down from heaven. In a word, they were meeting the difficulty which has been met by Christianity in the latter half of the nineteenth century. The least they could do was to deny that the Qur’an was uncreated.
