They thereupon emigrated to the number of six hundred, some of them going to their countrymen in Chaibar, and some settling in Jericho and Adraat (June-July, 625). The war against the Nadhirites was, later on, justified by Mahomet through a revelation of the Koran, which read: "All in the heavens and earth praise God; He is the most honored, the most wise. He it is who drove out the unbelievers amongst the people of the Book from their dwelling places (Kainukaa), to send them to those who had already emigrated. You thought not that they would go forth, they themselves thought that their strong places would protect them from God himself, but God attacked them unexpectedly, and threw terror into their hearts, so that their houses were destroyed with their own hands, as well as laid waste by believers." The exiled Benu-Nadhir, who had remained in Arabia, did not accept their misfortune quietly, but exerted themselves to form a coalition with the enemies of Mahomet in order to attack him with combined forces. Three respected Nadhirites, Hujej, Kinanah Ibn-ol-Rabia, and Sallam Ibn Mishkam, incited the Koraishites in Mecca, in alliance with the mighty tribe of the Ghatafan and others, to make war against the haughty tyrannical prophet, who was daily becoming more powerful and more cruel. The enemies of Mahomet in Mecca, though filled with rage against him, were first incited by the Jews to join battle with him.
Through the activity of the Nadhirites the Arabian tribes were induced to join in the war. They found it more difficult, however, to induce their co-religionists, the Benu-Kuraiza, to take part. Kaab-Ibn-Assad, the governor of Kuraiza, at first would not receive the Nadhirite Hujej, who had desired his protection, because his tribe had made an alliance with Mahomet and the Moslems, and he was so guileless as to rely on Mahomet's word. Hujej managed to convince him of the danger which threatened the Jews, and to persuade him that the victory of so many allies over the less numerous Moslems was certain. The Benu-Kuraiza yielded to his arguments. Ten thousand of the allied troops took the field, and intended to surprise Medina. Mahomet, forewarned by a deserter, would not allow his army, which was inferior in numbers, to fight a pitched battle. He fortified Medina by surrounding it with a deep ditch and other defenses. The Arabs, accustomed to fight in single combat, vainly discharged their arrows against the fortifications. Mahomet succeeded finally in sowing the seeds of mutual distrust among the chief allies, viz., the Koraishites, the Ghatafan and the Jews.
The "War of the Fosse" terminated favorably for Mahomet, and very unhappily for the Jews, upon whom the whole of his wrath now fell. On the day after the departure of the allies, Mahomet, with 3000 men, took the field against Kuraiza, announcing that he was thus obeying an express revelation. His next step was to arouse the enthusiasm of his followers in the cause of the war. "Let him that is obedient offer up his prayers in the neighborhood of Kuraiza," was the formula with which he exhorted them. The Jews, unable to resist in a battle, retired to their fortresses, which they put into a state of defense. Here they were besieged by Mahomet and his troops for twenty-five days (February-March, 627). Food then began to fail the besieged, and it became necessary to think of capitulation. They besought Mahomet to treat them as he had treated their brethren, the Nadhirites, viz., allow them to withdraw with their wives, their children, and a portion of their property. The vindictive prophet, however, refused their request, and demanded unconditional surrender.
Nearly 700 Jews, amongst them the chiefs Kaab and Hujej, were ruthlessly slaughtered in the market-place, and their bodies thrown into a common grave. The market-place was thenceforth called the Kuraiza Place. And all this was done in the name of God! The Koran makes reference to it in the following verse: "God drove out of their fortresses those of the people of the Book [the Jews] who assisted the allies, and he cast into their hearts terror and dismay. Some of them you put to flight, some you took captive; he has caused you to inherit their land, their houses, and their wealth, and a land which you have not trodden; for God is almighty." The women were bartered for weapons and horses. Mahomet wished to retain one of the captives, a beautiful girl, Rihana by name, as his concubine; she, however, proudly rejected his advances. Only one of the Kuraiza remained alive, a certain Zabir Ibn-Bata, and he only by the intercession of Thabit, one of his friends. Full of joy, the latter hastened to the aged Zabir, to tell him of his fortune. "I thank thee," said the Jewish sage, who lay in fetters; "but tell me what has become of our leader Kaab?" "He is dead," answered Thabit. "And Hujej Ibn-Achtab, the prince of the Jews?" "He is dead," he again replied. "And Azzel Ibn-Samuel, the fearless warrior?" "He, too, is dead," was his answer again. "Then I do not care to live," said Zabir. The old man begged that he might die by the hands of his friend. His wish was granted.
A year later came the turn of the Jews in the district of Chaibar, a confederacy of small Jewish states. This war, however, was protracted into a long campaign, because the province had a number of fortresses which were in a good state of repair, and were well defended. The exiled Nadhirites in Chaibar roused their comrades to vigorous resistance. The Arab races of Ghatafan and Fezara had promised assistance. The leading spirit of the Chaibarites was the exiled Nadhirite, Kinanah Ibn Rabia, a man who possessed indomitable firmness and courage. He was called the King of the Jews, and was abetted by Marhab, a giant of Himyarite extraction. Mahomet, before the beginning of the war, turned in prayer to God, beseeching him to grant a victory over the Jews of Chaibar. The war, in which Mahomet employed 14,000 warriors, lasted almost two months (Spring 628).
The war against Chaibar assumed the same character as that which was waged against the other Jewish tribes. It was begun by the cutting down of the palm trees, and the siege of the small fortresses, which surrendered after a short resistance. Mahomet met the most vigorous resistance at the fortress Kamus, which was built on a steep rock. The Mahometans were several times beaten back by the Jews. Abu-Bekr and Omar, Mahomet's two bravest generals, lost their distinction as unconquered heroes before the walls of Kamus. Marhab performed wonderful feats of valor, to avenge the death of his brother, who had fallen earlier in the war.
When Mahomet sent his third general, Ali, against him, the Jewish hero addressed him thus: "Chaibar knows my valor, I am Marhab the hero, well armed and tried in the field." He then challenged Ali to single combat. But his time had come. He fell at the hands of his peer. After many attempts, the enemy succeeded in effecting an entrance into the fortress. How the captives fared is not known. Kinanah was captured and put on the rack in order to force him to discover his hidden treasures. But he bore pain and even death without uttering a word. After the fortress had fallen, the Jews lost courage, and the other fortresses surrendered on condition that the garrisons should be allowed to withdraw. They were subsequently allowed to take possession of their lands, and only had to pay as an annual tribute one half of their produce. The Mahometan conquerors took possession of all the movable property, and returned home laden with the spoils of the Jews. Fadak, Wadil-Kora and Taima also submitted. Their inhabitants, according to agreement, were allowed to remain in their land. The year 628 everywhere was distinguished by fatalities for the Jews. It marks the victory of Mahomet over the Jews of Chaibar, the decay of the last independent Jewish tribes, and the persecution of the Jews of Palestine by the Emperor Heraclius, who had, for a short time, again taken up arms. The sword which the Hasmoneans had wielded in defense of their religion, and which was in turn used by the Zealots and the Arabian Jews, was wrung from the hands of the last Jewish heroes of Chaibar, and henceforth the Jews had to make use of another weapon for the protection of their sanctuary.
Mahomet had brought two pretty Jewish women with him from the war at Chaibar: Safia, the daughter of his inveterate enemy, the Nadhirite Hujej,
