By far the more enduring influence was that of Judaism. Many Jewish tribes were settled in Arabia, and the ancient traditions of the Jewish race, the great figures of Abraham, Lot, and Noah were set vividly before the eyes of the Arabs. There was every indication that a religious teacher might use the existing elements of Judaism and Christianity to produce a monotheistic faith, partaking of their nature, and for a time Mahomet endeavoured to bring both forms within the scope of his mission. But compromise, whether with idolaters or Jews, was found to be impossible, and here religious and political ideals are inextricably blended. If Mahomet had acquiesced in the Jewish religion, had submitted to the sovereignty of Jerusalem as the Holy Place, he would have found it impossible to have established his supremacy in Medina, and the religion of Islam as he conceived it would have been overriden by the older and more hallowed faith of the Jews. He saw the danger, and his dominant spirit could not allow the existence of an equal or superior power to his own. With that fiery daring and supreme belief in his destiny which characterised him in later life, he cast away all pretensions to friendliness either with the Jews or the Christians, and steered his followers triumphantly through the perils that beset every adherent to an idea. But in compelling acceptance of his central thesis of the unity of the Godhead, he showed signal wisdom and knowledge of men. He was himself by no means impervious to the value of tradition, and never conceived his faith as having no historical basis in the religious legends of his birthplace. That the Muslim belief possesses institutions such as the reverence for the Kaaba, the rite of Pilgrimage, the acceptance of Mecca as its sacred city, is due to its founder's love of his native place, and the ceremonial of which his own creed was really the inseparable outcome. Besides his recognition of the need of ritual, he was fully aware of the repugnance of most men to the wholly new. Whenever possible he emphasized his connection with the ancient ceremonies of Mecca in their purer form, and as soon as his power was sufficient, he enforced the recognition of his claims upon the city itself.
