Mahomet thereupon ordered her to be put to death, and commanded his troops to use none of the cooking utensils of the Jews before they had been scalded. The rest of the Jews did not even now give up the hope of freeing themselves of their arch-enemy. They intrigued against him, and made common cause with some ill-disposed Arabs. The house of a Jew, Suwailim, in Medina was the appointed meeting-place for the malcontents, whom Mahomet and his fanatic followers named "the hypocrites" (Munafikun). A traitor betrayed them, and Suwailim's house was burnt to the ground. The Jews in Arabia felt real joy at Mahomet's death (632), because they, like others, believed that the Arabs would be cured of their false belief that he was a higher being endowed with immortality. But fanaticism, together with the love of war and conquest, had already taken possession of the Arabians, and they accepted the Koran as a whole, alike its revolting features and the truths borrowed from Judaism, as the irrefragable Word of God. Judaism had reared in Islam a second unnatural child. The Koran became the book of faith of a great part of humanity in three parts of the world, and, being full of hostile expressions against the Jews, it naturally urged on the Mahometans to acts of hostility against the Jews. This is paralleled by the effect which the Apostles and the Evangelists produced upon the Christians. So great was the fanaticism of the second Caliph, Omar, a man of a wild and energetic nature, that he broke the treaty made by Mahomet with the Jews of Chaibar and Wadil-Kora. He drove them from their lands, as he did also the Christians of Najaran, in order that the holy ground of Arabia might not be desecrated by Jews and Christians. Omar assigned the landed property of the Jews to the Mahometan warriors, and a strip of land near the town of Kufa, on the Euphrates, was given them in return (about 640). But as no evil in history is quite devoid of good consequences, the dominion of Islam furthered the elevation of Judaism from its deepest degradation. CHAPTER IV. THE AGE OF THE GEONIM.
