"The Qurān is one of the world’s classics which cannot be translated without grave loss. It has a rhythm of peculiar beauty and a cadence that charms the ear. Many Christian Arabs speak of its style with warm admiration, and most Arabists acknowledge its excellence… indeed it may be affirmed that within the literature of the Arabs, wide and fecund as it is both in poetry and in elevated prose, there is nothing to compare with it."
