[73] The Koran claims to be, not the composition of Mahomet, but a divine revelation, which he had to report with the minutest accuracy. It professes to republish what had been already delivered to Abraham, Moses, and Christ, and now more explicitly, to Mahomet. It teaches I. The Unity of God. II. The Ministrations of Angels and Prophets. III. Absolute Predestination, or Fatalism. IV. The Resurrection and Future Judgment. It rejects the Trinity, and Godhead of our Lord, and insists on the divine mission of Mahomet. In this last particular, and in the respect shown to Christ, it differs from Judaism. [74] ‘If he is the Messiah,’ she said, ‘the poison cannot hurt him; if he is not, he is an impostor, and deserves death.’ [75] When Chosroes received Mahomet’s letter, inviting him to embrace Islamism, he disdainfully tore it in pieces. When Mahomet heard of this he exclaimed, ‘Even so shall his kingdom be torn.’ Doubtless Abu Beker had this in mind when he sent out the expedition. [76] On the morning of the assault on Jerusalem, the address of Moses to the Israelites in the Koran, ‘Enter, O ye people, into the Holy Land, which God hath destined for you,’ was shouted aloud after morning prayer, by the whole besieging army. [77] Omar had succeeded Abu Beker, A.D. 633, less than two years after the death of the Prophet. He was the Caliph who burned the Alexandrian library, and was the first of the Ommiades. CHAPTER X.
