And after that Zeid was put to death. Mahomet was powerless to retaliate, and was obliged to suffer from afar the murder of his fellow-believers.
The fate of these six Muslim gave courage to Mahomet's enemies everywhere, and prompted even his friends to treachery. The Beni Aamir, a branch of the great Hawazin tribe dwelling between the Beni Asad and the Beni Lahyan, were friendly towards Medina, and sent Mahomet gifts as a guarantee. These Mahomet refused to receive unless the tribe became converts to Islam. He knew the danger of compromise—his Meccan experiences had not faded from his mind; moreover, he recognised that in his present weakened position firmness was essential. He could not open the gates of his fortress even a chink without letting in a flood before which it must topple into ruin.
But their chief would not be so coerced, neither would he give up his ancestral faith without due examination of that offered in its stead. He demanded that a party of Muslim should accompany him back to his own people and strive by reasoning and eloquence to convert them to Islam. After much deliberation, for he was chary of sending any of his chosen to what would be swift death in the event of treachery, Mahomet consented, and gave orders for a party of men skilled in their faith to accompany Abu Bera back to his people. The men were received in all honour, and were escorted as befitted their position as far as Bir Mauna, where they halted, and a Muslim messenger was sent with a letter to the chief of another branch of the same tribe. This leader, Aamir ibn Sofail, immediately put the messenger to death, and called upon his allies to exterminate the followers of the blasphemous Prophet. But the tribe refused to break Abu Bera's pledge, so Aamir, determined to root them out, appealed to the Beni Suleim, Mahomet's avowed enemies, and with their aid proceeded to Bir Mauna. There they fell upon the band of Muslim and slaughtered them to a man, then returned to their desert fastnesses, proudly confident in their ability to elude pursuit. The news was carried to Mahomet, and at first he was convinced that Abu Bera had betrayed him. His followers, who had brought the news, had fallen upon and killed some luckless members of the Beni Aamir in reprisal, and Mahomet acclaimed their action. When, however, he heard from Abu Bera that he and his tribe had been faithful to their pledge, he paid blood money for the murdered men; then calling his people together he solemnly cursed each tribe by name who had dared to attack the Faithful by treachery.
But the incident did not end here. Mahomet could not compass the destruction of the Beni Aamir; they were too powerful and dwelt too far off for his vengeance to assail them, but the Beni Nadhir, the second Jewish tribe within the Prophet's territory, were near, and they were confederate with the treacherous people. Mahomet's action was swift and effective. Force was his only temporal weapon; compulsion his only policy.
The command went forth through the lips of Mosleima:
"Thus saith the Prophet of the Lord: Ye shall go forth out of my land within a space of ten days; whosoever that remaineth behind shall be put to death."
The Beni Nadhir were aghast and trembling. They urged their former treaties with Mahomet, and the antiquity of their settlements. It was impossible that they should break up their homesteads thus suddenly and depart forlorn into an unknown land. But Mahomet was obdurate, with that same fixity of purpose which was everywhere the keynote of his dominance.
"Hearts are changed now," was the only reply to their prayers, their entreaties, and their throats. Abdallah, leader of the Beni Aus and Khazraj, sought desperately for a reconciliation, but to no purpose; the die was cast. Then the Jews, brought to bay and careless with the despair of impotence, refused to obey the command, and prepared to encounter the wrath of Allah and the vengeance of his emissary.
"Behold the Jews prepare to fight: great is the Lord!" the Prophet declared when the news was brought to him.
He was sure of his victim, and ruthless in destruction. All things were made ready for the undertaking. The army was assembled and the march begun. Ali carried the great green banner of the Prophet towards the stronghold of his enemies. The Beni Nadhir were invested in their own quarters, the date trees lying outside their fort were burned, their fields were laid waste. For three weeks the siege endured, each day bringing the miserable garrison nearer to the inevitable privations and final surrender. At last the Jews recognised the hopelessness of their lot and came to reluctant terms, submitting to exile and agreeing to depart immediately.
