[Sidenote: I. Ministry at Mecca, A.D. 609-622. Success at Mecca limited.] It is only in the first of these periods that Islam at all runs parallel with Christianity. The great body of his fellow-citizens rejected the ministry of Mohammed and bitterly opposed his claims. His efforts at Mecca were, therefore, confined to teaching and preaching and to the publishing of the earlier "Suras," or chapters of his "Revelation." After some thirteen years spent thus his converts, to the number of about a hundred and fifty men and women, were forced by the persecution of the Coreish (the ruling tribe at Mecca, from which Mohammed was descended) to quit their native city and emigrate to Medina.[35] A hundred more had previously fled from Mecca for the same cause, and found refuge at the court of the Negus, or king of Abyssinia; and there was already a small company of followers among the citizens of Medina. At the utmost, therefore, the number of disciples gained over by the simple resort to teaching and preaching did not, during the first twelve years of Mohammed's ministry, exceed a few hundreds. It is true that the soil of Mecca was stubborn and (unlike that of Judea) wholly unprepared. The cause also, at times, became the object of sustained and violent opposition. Even so much of success was consequently, under the peculiar circumstances, remarkable. But it was by no means singular. The progress fell far short of that made by Christianity during the corresponding period of its existence,[36] and indeed by many reformers who have been the preachers of a new faith. It gave no promise whatever of the marvelous spectacle that was about to follow.
