"Here, therefore, its merits as a literary production should perhaps not be measured by some preconceived maxims of subjective and aesthetic taste, but by the effects which it produced in Muhammad's contemporaries and fellow countrymen. If it spoke so powerfully and convincingly to the hearts of his hearers as to weld hitherto centrifugal and antagonistic elements into one compact and well organised body, animated by ideas far beyond those which had until now ruled the Arabian mind, then its eloquence was perfect, simply because it created a civilised nation out of savage tribes, and shot a fresh woof into the old warp of history."
