saw that his disciples amongst the Jews still continued to observe the Jewish laws, and to abstain from camel's flesh, and they said to him, "If the Torah be a divine book, then let us follow its teachings." Since Mahomet was thoroughly an Arab, he could not join Judaism, and he perceived that the Arabs would not conform to religious customs which were quite strange to them. So it only remained for him to break with the Jews definitely. He thereupon published a long Sura (called the Sura of the Cow), full of invectives against the Jews. He altered the position assumed in prayer, and decreed that the believers should no longer turn their faces towards Jerusalem, but towards Mecca and the Kaaba. He discarded fasting on the day of Atonement (Ashura), and instituted instead the holy month Ramadhan, as had been customary among the Arabs from very ancient times. He was obliged to withdraw much of what he had in the beginning given out as God's revelation. Mahomet now asserted that the Torah had contained many allusions to his appearance and calling as a prophet, but that the Jews had expunged the passages. At first he declared that the Jews were possessed of the true faith; later on he said that they honored Ezra (Ozaïr) as the son of God, just as the Christians did Jesus, and that the Jews were consequently to be regarded as infidels. His hatred against the Jews, who refused to accept his prophecies, and saw through his designs, continually widened the breach between them and him. Although he hated the Jews in his innermost heart, yet he did not venture to provoke them by acts of violence, because his authority was not sufficiently great, and the Jews outnumbered his followers. But after the battle at Bedr (in the winter of 624), when the small body of Mahometans gained a victory over the numerous Koraishites, the situation changed. Mahomet, whose power was greatly increased through this victory, exchanged the attitude of a humble prophet for that of a fanatical tyrant, to whom any measure, even assassination, was a justifiable means of freeing himself from his enemies. However, he was prudent enough to avoid becoming involved in disputes with the powerful Jewish tribes; he began with the weak and defenseless. A poetess, Asma, daughter of Merwan, who was of Jewish descent, and married to an Arab, was murdered at night whilst asleep (because she had composed satires against the false prophet), and he commended the murderer. Thereupon the Jewish tribe Kainukaa experienced his religious wrath. It was the weakest of the Jewish-Arabian tribes, and to it belonged that Pinehas Ibn-Azura, whose sarcastic wit had made Mahomet appear in a ridiculous light. The pretext was of the slightest kind. A Mahometan had killed a Jew on account of a poor practical joke, and the Kainukaa avenged his death. Mahomet thereupon challenged them to profess Islam, or to accept war as the alternative. They replied: "We are, it is true, for peace,
