But only a small number of the Jews of Medina joined the band of believers, particularly when they perceived his selfish efforts, his haughtiness, and his insatiable love of women. They bore in their hearts too high an ideal of their ancient prophets to place this enthusiast, who longed after every beautiful woman, on an equal footing with them. "See him," said the Jews, "he is not satisfied with food, and has no other desire than that of being surrounded by women. If he is a prophet, he should confine himself to his duties as a prophet, and not turn to women." Other Jews said: "If Mahomet is a prophet, he should appear in Palestine, for only in that place God appears unto his elect." The Jews also objected to him, saying, "You pride yourself on being of Abraham's faith, but Abraham did not use the flesh and milk of camels." Mahomet's chief opponents on the Jewish side were Pinehas Ibn-Azura, a man of caustic wit, who seized every opportunity to make Mahomet appear ridiculous; furthermore, the far-famed Kaab Ibn-Asharaf, the offspring of an Arab father and a Jewish mother; a poet, Abu-Afak, an old man more than a hundred years old, who endeavored to arouse hate against Mahomet amongst the ignorant Arabs; and Abdallah, the son of Saura, who was looked upon as the most learned Jew in Hejas. Pinehas is the author of a witty answer to Mahomet's invitation to the Jewish tribe of Benu-Kainukaa to accept Islam. Mahomet, in his epistle, had used the words: "Lend yourselves unto God as a beautiful pledge." Pinehas answered, "God is so poor that He borrows from us!" Thus the Jewish opponents of Mahomet placed a ridiculous meaning on his sayings and revelations, and treated him contemptuously, not anticipating that the fugitive from Mecca, who had come to Medina for assistance, would shortly humble and in part destroy their tribes, and that he would control the destiny of many of their co-religionists in times to come. They relied too much on their own courage and strength, and forgot that the most dangerous enemy is he whom one disregards too much. Mahomet, indeed, with sly dissimulation, at first accepted the contempt bestowed on him by the Jews with apparent equanimity. He advised his disciples, "Fight only in a becoming manner with the people who believe in the Holy Writ (Jews), and say: We believe in that which has been revealed to us and to you. Our God is the same as yours, and we are faithful to Him." But the mutual discontent made it difficult to maintain peace permanently. On the one side, the Jews did their best to alienate Mahomet's followers. They succeeded in prejudicing the first man in Medina, the Chazrajite Abdallah Ibn-Ubey, against Mahomet, so that he remained antagonistic to Mahomet to the end of his days. This man was about to be elected king of his town, but through the arrival of Mahomet he had been cast into the shade. On the other side, his followers urged him to declare to what extent he held to Judaism. They 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, and would gladly maintain our alliance with you; but since you desire to make war upon us, we will show that we have no fear." They reckoned upon the assistance of the tribes of Nadhir and Kuraiza, who were their co-religionists, and withdrew to their fortresses at Medina. Mahomet collected his troops, and besieged the Kainukaa. Had the numerous Jews of northern Arabia, Nadhir, Kuraiza, and those of Chaibar, who, like the Kainukaa, were threatened, come to their assistance, and had they, before it was too late, made an offensive and defensive alliance, they would have been able to crush Mahomet and his straggling followers, on whose fidelity, moreover, he could not entirely rely. But the Jews, like the Arabs, were divided, and each tribe had only its own interests in view. The Kainukaa fought desperately for fifteen days, expecting re-inforcements from their co-religionists. But as these did not come, they surrendered to the enemy. Mahomet had all the Jews of Kainukaa put in chains with the intention of killing them; but a word from Abdallah Ibn-Ubey, their ally, made him draw back with alarm from his purpose. Abdallah laid hold of his shirt of mail, and said: "I will not let you go until you promise me to spare the captives; for they constitute my strength; they have defended me against the black people and the red people." To which Mahomet replied: "Let them be free; may God condemn them, and Abdallah with them!" The Jews of Kainukaa, 700 in number, were obliged to leave their possessions behind, and they set out for Palestine in a most destitute condition (February, 624). They settled in Batanea, whose chief town was Adraat, where they were probably received in a fraternal manner by their co-religionists, who, at this time, were free from the Byzantine yoke.
After the victory over the Kainukaa, Mahomet communicated to the Moslems a revelation against the Jews, which deprived them of every protection: "O ye believers, choose ye not Jews and Christians as allies; they may protect themselves. He who befriends them is one of them; God tolerates no sinful people." This exclusion was less harmful to the Christians, as they were not numerously represented in northern Arabia, and generally kept themselves neutral. The Jews, on the contrary, who were accustomed to independence, and who were full of warlike courage, became involved in numerous disputes by this act of outlawry. Their former allies for the most part renounced them, and at Mahomet's bidding, took spiteful vengeance on them.
With this mutual, deadly hatred existing between Mahomet and the Jews, it is said that the Benu-Nadhir invited him one day to
