The very institution of prayer was jeered at by the Arabs to whom Muḥammad first delivered his message, and one of the hardest parts of his task was to induce in them that pious attitude of mind towards the Creator, which Islam inculcates equally with Judaism and Christianity, but which was practically unknown to the heathen Arabs. This self-sufficiency and this lack of the religious spirit, joined with their intense pride of race, little fitted them to receive the teachings of one who maintained that “The most worthy of honour in the sight of God is he that feareth Him most” (xlix. 13). No more could they brook the restrictions that Islam sought to lay upon the licence of their lives; wine, women, and song, were among the things most dear to the Arab’s heart in the days of the ignorance, and the Prophet was stern and severe in his injunctions respecting each of them. Thus, from the very beginning, Islam bears the stamp of a missionary religion that seeks to win the hearts of men, to convert them and persuade them to enter the brotherhood of the faithful; and as it was in the beginning, so has it continued to be up to the present day, as will be the object of the following pages to show. CHAPTER III. THE SPREAD OF ISLAM AMONG THE CHRISTIAN NATIONS OF WESTERN ASIA. After the death of Muḥammad, the army he had intended for Syria was despatched thither by Abū Bakr, in spite of the protestations made by certain Muslims in view of the then disturbed state of Arabia. He silenced their expostulations with the words: “I will not revoke any order given by the Prophet. Medina may become the prey of wild beasts, but the army must carry out the wishes of Muḥammad.” This was the first of that wonderful series of campaigns in which the Arabs overran Syria, Persia and Northern Africa—overturning the ancient kingdom of Persia and despoiling the Roman Empire of some of its fairest provinces. It does not fall within the scope of this work to follow the history of these different campaigns, but, in view of the expansion of the Muslim faith that followed the Arab conquests, it is of importance to discover what were the circumstances that made such an expansion possible.
