faithful friend and disciple, Abu Bekr, to the friendly town of Medina which adopted his doctrine. Hostilities followed between Mecca and Medina which ended at last in a treaty. Mecca was to adopt the worship of the One True God and accept Muhammad as his prophet, but the adherents of the new faith were still to make the pilgrimage to Mecca just as they had done when they were pagans. So Muhammad established the One True God in Mecca without injuring its pilgrim traffic. In 629 Muhammad returned to Mecca as its master, a year after he had sent out these envoys of his to Heraclius, Tai-tsung, Kavadh and all the rulers of the earth.
Then for four years more until his death in 632, Muhammad spread his power over the rest of Arabia. He married a number of wives in his declining years, and his life on the whole was by modern standards unedifying. He seems to have been a man compounded of very considerable vanity, greed, cunning, self-deception and quite sincere religious passion. He dictated a book of injunctions and expositions, the Koran, which he declared was communicated to him from God. Regarded as literature or philosophy the Koran is certainly unworthy of its alleged Divine authorship.
