Note 1 — Chapter III · THE SPREAD OF ISLAM AMONG THE CHRISTIAN NATIONS OF WESTERN ASIA.

A great historian1 has well put the problem that meets us here, in the following words: “Was it genuine religious enthusiasm, the new strength of a faith now for the first time blossoming forth in all its purity, that gave the victory in every battle to the arms of the Arabs and in so incredibly short a time founded the greatest empire the world had ever seen? But evidence is wanting to prove that this was the case. The number was far too small of those who had given their allegiance to the Prophet and his teaching with a free and heartfelt conviction, while on the other hand all the greater was the number of those who had been brought into the ranks of the Muhammadans only through pressure from without or by the hope of worldly gain. K͟hālid, ‘that sword of the swords of God,’ exhibited in a very striking manner that mixture of force and persuasion whereby he and many of the Quraysh had been converted, when he said that God had seized them by the hearts and by the hair and compelled them to follow the Prophet. The proud feeling too of a common nationality had much influence—a feeling which was more alive among the Arabs of that time than (perhaps) among any other people, and which alone determined many thousands to give the preference to their countryman and his religion before foreign teachers. Still more powerful was the attraction offered by the sure prospect of gaining booty in abundance, in fighting for the new religion and of exchanging their bare, stony deserts, which offered them only a miserable subsistence, for the fruitful and luxuriant countries of Persia, Syria and Egypt.”
