The party of the Ansars, or Helpers, included some lukewarm converts who retained an ill-concealed predilection for idolatry. These were headed by Abdullah Ibn Ubai, a man with some claims to distinction. They ostensibly joined Islam, but in secret were disaffected. They often were a source of considerable danger to the newborn commonwealth and required unceasing watchfulness on the part of the Prophet. Towards them he always showed the greatest patience and forbearance, hoping in the end to win them over to the faith, which expectations were fully justified by the result. With the death of 'Abdullah Ibn Ubai, his party which were known as the party of the "Munafiqeen" (the Hypocrites) disappeared.
The Jews Present a Problem
The Jews who constituted the third party of the Medinites were, however, the most serious element of danger. No kindness or generous treatment on the part of the Prophet would seem to satisfy them. They soon broke off and ranged themselves with the enemies of the new faith. They did not hesitate to declare openly that they preferred idolatry, with its attendant evils, to the faith of Islam. Thus, the Prophet had to keep an eye on his enemies outside Medina, on the one hand, and those within the city on the other. The Meccans who had sworn Muhammad's death were well acquainted, thanks to the party of the Hypocrites and of the Jews at Medina, with the real forces of the Muslims. They also knew that the Jews had accepted Muhammad's alliance only from motives of temporary expendience and that they would break away from him to join the idolaters as soon as the latter showed themselves in the vicinity of Medina. The safety of the state required the proscription of the traitors who were secretly giving information to the common enemy. About six men were executed for high treason of this nature.
