by Muhammadan theologians, but such quotations refer to his traditional sayings known as "Hadîs," which have been handed down from mouth to mouth with the strictest regard to genealogical continuity. It would probably be impossible for any Arabic scholar to produce a translation of the Korân which would defy criticism, but this much may be said of Sale's version: just as, when it first appeared, it had no rival in the field, it may be fairly claimed to-day that it has been superseded by no subsequent translations. Equally remarkable with his translation is the famous Preliminary Discourse which constitutes a tour de force when we consider how little critical work had been done in his day in the field of Islamic research. Practically the only works of first-class importance were Dr. Pocock's Specimen Historio Arabum, to which, in his original Address to the Reader, Sale acknowledges his great indebtedness, and Maracci's Korân. In spite of the vast number of eminent scholars who have worked in the same field since the days of George Sale, his Preliminary Discourse still remains the best Introduction in any European language to the study of the religion promulgated by the Prophet of Arabia; but as Wherry says: "Whilst reading the Preliminary Discourse as a most masterly, and on the whole reliable, presentation of the peculiar doctrines, rites, ceremonies, customs, and institutions of Islam, we recognize the fact that modern research has brought to light many things concerning the history of the ancient Arabs which greatly modify the statements made in the early paragraphs." For many centuries the acquaintance which the majority of Europeans possessed of Muhammadanism was based almost entirely on distorted reports of fanatical Christians which led to the dissemination of a multitude of gross calumnies. What was good in Muhammadanism was entirely ignored, and what was not good, in the eyes of Europe, was exaggerated or misinterpreted. It must not, however, be forgotten that the central doctrine preached by Muhammad to his contemporaries in Arabia, who worshipped the Stars; to the Persians, who acknowledged Ormuz and Ahriman; the Indians, who worshipped idols; and the Turks, who had no particular worship, was the unity of God, and that the simplicity of his creed was probably a more potent factor in the spread of Islam than the sword of the Ghazis. Islam, although seriously affecting the Christian world, brought a spiritual religion to one half of Asia, and it is an amazing circumstance that the Turks, who on several occasions let loose their Central Asian hordes over India, and the Middle East, though irresistible in the onslaught of their arms, were all conquered in their turn by the Faith of Islam, and founded Muhammadan dynasties. The Mongols of the thirteenth century did their best to wipe out all traces of Islam when they sacked Baghdad, but though the Caliphate was
