Moḥammad now (612) came forward as the Apostle of the One God to the people of Arabia: he was at last well assured that his God was of a truth _the_ God, and that He had indeed sent him with a message to his people, that they too might turn from their idols and serve the living God. He was in the minority of one, but he was no longer afraid; he had learnt that self-trust which is the condition of all true work. At first he spoke to his near kinsmen and friends; and it is impossible to overrate the importance of the fact that his closest relations and those who lived under his roof were the first to believe and the staunchest of faith. The prophet who is _with_ honour in his own home need appeal to no stronger proof of his sincerity, and that Moḥammad _was_ ‘a hero to his own valet’ is an invincible argument for his earnestness. The motherly Khadeejeh had at once, with a woman’s instinct, divined her husband’s heart and confirmed his fainting hope by her firm faith in him. His dearest friends, Zeyd and ´Alee, were the next converts; and though, to his grief, he could never induce his lifelong protector, Aboo-Ṭálib, to abandon the gods of his fathers, yet the old man loved him none the less, and said, when he heard of ´Alee’s conversion, ‘Well, my son, he will not call thee to aught save what is good; wherefore thou art free to cleave unto him.’ A priceless aid was gained in the accession of Aboo-Bekr, who succeeded Moḥammad as the first Khalif of Islám, and whose calm judgment and quick sagacity, joined to a gentle and compassionate heart, were of incalculable service to the faith. Aboo-Bekr was one of the wealthiest merchants of Mekka, and exercised no small influence among his fellow-citizens, no less by his character than his position. Like Moḥammad, he had a nickname, Eṣ-Ṣiddeeḳ, ‘The True:’ _The True_ and _The Trusty_,—no mean augury for the future of the religion! Five converts followed in Aboo-Bekr’s steps; among them ´Othmán, the third Khalif, and Ṭalḥah, the man of war. The ranks of the faithful were swelled from humbler sources. There were many negro slaves in Mekka, and of them not a few had been predisposed by earlier teaching to join in the worship of the One God; and of those who were first converted was the Abyssinian Bilál, the original Muëddin of Islám, and ever a devoted disciple of the Prophet. These and others from the Ḳureysh raised the number of Muslims to more than thirty souls by the fourth year of Moḥammad’s mission—thirty in three long years, and few of them men of influence!
