With regard to the first-named criterion, there is a growing opinion among students of religious history that Muhammed may in a real sense be regarded as a prophet of certain truths, though by no means of truth in the absolute meaning of the term. The shortcomings of the moral teaching contained in the Koran are striking enough if judged from the highest ethical standpoint with which we are acquainted; but a much more favourable view is arrived at if a comparison is made between the ethics of the Koran and the moral tenets of Arabian and other forms of heathenism which it supplanted.
The method followed by Muhammed in the promulgation of the Koran also requires to be treated with discrimination. From the first flash of prophetic inspiration which is clearly discernible in the earlier portions of the book he, later on, frequently descended to deliberate invention and artful rhetoric. He, in fact, accommodated his moral sense to the circumstances in which the rĂ´le he had to play involved him.
