Ismaili History 321 - The hypocrites
Though emigration to Medina had given Muhammad a certain amount of respite, it increased opposition to his cause tenfold. While at Mecca, the malice of the Qoraish found vent in tormenting the Muslims, but now it was bent on the latter's destruction. The Bedouin tribes, who had so far been mere spectators of the Muslims's persecutions were also stirred at the growth of Islam in Medina. The Jews, being at a distance, were also quiet so far, but now that the Muslims were their next door neighbours in Medina, they could not watch the steady growth of Islam without a sting of jealousy and they rose in opposition. Distinct from all these, and of a singular nature, another wave of opposition set in, in the camp, known in the Islamic phraseology as that of the hypocrites. These were the men who had not the pluck to come out into the open. So they joined the faith with an object of undermining it from within. A certain man, Abdullah bin Ubay, was at their head. Before the immigration of Muhammad, both Banu Aws and Khazraj, wearied by their long drawn-out mutual hostility, which had often erupted into fighting and had exacted a heavy toll of life, had decided to put an end to this state of affairs and to set up a form of administration in Medina which should have the support of both tribes and should also be acceptable to the three Jewish tribes. For this purpose, it had been agreed that Abdullah bin Ubay bin Salul, chief of the Khazraj, should be elected king of Medina. This plan had not yet been put into effect when Muhammad was invited to come to Medina. But Muhammad's presence eclipsed his personality, and he dwindled into a nonentity. He was deeply chagrined at the loss of a crown. At the outset, he offered some opposition, but beholding the rapid growth of Islam, he thought hypocrisy would be a best tool of revenge. Thus he put on the mask of Islam, and thenceforward till his last breath, he left no stone unturned to bring Islam into trouble.
