Note 5 — Chapter X · THE SPREAD OF ISLAM IN CHINA.

The army of seven thousand Berbers that sailed from Africa in 711 under the command of Ṭāriq (himself a Berber) to the conquest of Spain, was composed of recent converts to Islam, and their conversion is expressly said to have been sincere: learned Arabs and theologians were appointed, “to read and explain to them the sacred words of the Qurʼān, and instruct them in all and every one of the duties enjoined by their new religion.”5 Mūsạ̄, the great conqueror of Africa, showed his zeal for the progress of Islam by devoting the large sums of money granted him by the caliph ʻAbd al-Malik to the purchase of such captives as gave promise of showing themselves worthy children of the faith: “for whenever after a victory there was a number of slaves put up for sale, he used to buy all those whom he thought would willingly embrace Islam, who were of noble origin, and who looked, besides, as if they were active young men. To these he first proposed the embracing of Islam, and if, after cleansing their understanding and making them fit to receive its sublime truths, they were converted to the best of religions, and their conversion was a sincere one, he then would, by way of putting their abilities to trial, employ them. If they evinced good disposition and talents he would instantly grant them liberty, appoint them to high commands in his army, and promote them according to their merits; if, on the contrary, they showed no aptitude for their appointments, he would send them back to the common depôt of captives belonging to the army, to be again disposed of according to the general custom of drawing out the spoil by arrows.”6
