The safe arrival of Mahomet at his destination marks the turning-point in his career, which now became one of almost unbroken success; his intellectual superiority over both friends and enemies enabling him to profit by defeat little less than by victory. His policy appears to have been to bind his followers to himself and them to each other by every possible tie; he instituted brotherhoods between the Refugees and Helpers, which were to count as relationships for legal purposes, and having himself no sons, he contracted numerous marriages partly with the same end in view; e.g. with the infant daughter of Abu Bekr, Ayesha ('A'ishah), whose ability he appears to have discerned; and the unamiable Hafsa, daughter of Omar. Of his own daughters three were given to faithful allies, the one by whom his line is supposed to have been continued to our time, Fatima, was reserved for his cousin Ali. Owing to his efforts the alliance between the Refugees and Helpers resisted numerous attempts on the part of enemies to break it up, and only towards the end of the Prophet's life, when he appeared to favour Meccans unduly, do we hear of any bitterness between the two communities. The Medina Community. The population of Yathrib, or, as it may now be called, Medina, soon divided into three groups: Mahomet's united followers; the Jews; and a party known as the "Hypocrites," i.e. professing Moslems, who were lukewarm, or disaffected, among whom the most prominent is `Abdallah b. Ubayy, a Khazrajite chieftain, who is said to have himself aspired to be despot of Yathrib, and who till nearly the end of Mahomet's career figures somewhat as a leader of the opposition; of his importance there is no question, but the reason for it and the mode whereby he made it felt are often obscure. It would seem that the pagans remaining in Yathrib speedily adopted Islam after the Prophet's arrival, whence we hear little of serious opposition on their part. Coming in the capacity of prophet of the Israelitish God, Mahomet at first seems to have courted alliance with the Jews, and to have been ready to adopt their system with very slight modifications--similar to those which, according to his opinion, Jesus had come to introduce. The Jews met these advances by submitting him to examination in the intricacies of the _Torah_, and, finding him very poorly equipped, proceeded to denounce him as an imposter; one of his examiners is said to have even translated the _Torah_ into Arabic with a view of convicting him of ignorance and imposture. They are' further charged with exercising their magical arts on the Prophet and his followers, and to have succeeded thereby in producing barrenness among the Moslem women. Their conduct must not of course be judged by the statement of their enemies; it is however clear that Mahomet soon found that there was no possibility of compromising with them on religious questions, or of obtaining their loyal support;
