The Wahabi movement was a strictly puritan reformation. Its aim was the reform of abuses, the abolition of superstitious practices, and a return to primitive Islam. All later accretions--the writings and interpretations of the mediaeval theologians, ceremonial or mystical innovations, saint worship, in fact every sort of change, were condemned. The austere monotheism of Mohammed was preached in all its uncompromising simplicity, and the Koran, literally interpreted, was taken as the sole guide for human action. This doctrinal simplification was accompanied by a most rigid code of morals. The prayers, fastings, and other practices enjoined by Mohammed were scrupulously observed. The most austere manner of living was enforced. Silken clothing, rich food, wine, opium, tobacco, coffee, and all other indulgences were sternly proscribed. Even religious architecture was practically tabooed, the Wahabis pulling down the Prophet's tomb at Medina and demolishing the minarets of mosques as godless innovations. The Wahabis were thus, despite their moral earnestness, excessively narrow-minded, and it was very fortunate for Islam that they soon lost their political power and were compelled thenceforth to confine their efforts to moral teaching. Many critics of Islam point to the Wahabi movement as a proof that Islam is essentially retrograde and innately incapable of evolutionary development. These criticisms, however, appear to be unwarranted. The initial stage of every religious reformation is an uncritical return to the primitive cult. To the religious reformer the only way of salvation is a denial of all subsequent innovations, regardless of their character. Our own Protestant Reformation began in just this way, and Humanists like Erasmus, repelled and disgusted by Protestantism's puritanical narrowness, could see no good in the movement, declaring that it menaced all true culture and merely replaced an infallible Pope by an infallible Bible.
