Mohammed was born in Mecca towards the end of the sixth century. He was a member of the important family who had charge of the Ka’aba, which was a heathen temple that the Meccans had attempted to make a common meeting-ground for the whole of Arabia, by including within its limits the idols and symbols of worship that were respected by the different tribes. Some of these tribes had adopted Christianity and Judaism; so pictures even of Jewish and Christian saints were to be found within the walls of the Meccan temple.

The Mussulman historians of Mohammed’s life tell us that there had been in Arabia, for some years before the prophet came forward, a set of reformers called Hanīfs, who seem to have been half political and half religious, but to have been all of them convinced that some form of religion, purer than that represented by the Ka’aba, was needed to unite Arabia against its common foes. Some of these Hanifs ended by adopting Christianity or Judaism; others were inclined to the adoption of a more essentially national form of monotheism, which should retain the Ka’aba as its centre. The most notable of the latter party was Zaid ibn Amr, a man so much admired by Mohammed that he declared him a prophet, and in other ways professed his complete acceptation of his principles and teaching.

Mohammed by his marriage with Khadīja was certainly introduced into this set of reformers. Waraka ibn Nawfal was one of the most prominent Hanifs, and we have indisputable evidence that he was one of Khadija’s most intimate friends, both at the time of her marriage, and also at the time when her husband received his first revelation. Mohammed himself had been from childhood of a hysterical disposition, and was subject to fits, during which he saw visions, which on recovering consciousness he was able to recollect; consequently while in this company he became convinced that he was the expected prophet who was to bind Arabia together by a politico-religious system.

In placing himself at the head of the Hanif movement, Mohammed probably gave more prominence to the political aspect than had most of the former and less successful leaders. This is brought out by Koelle in his life of Mohammed; and indeed it is obvious that the man who could allow an unbelieving friend, even though a close relation, to play the important part in the building of his church that Abbās played in the second meeting on the eminence, was primarily a politician rather than a religious reformer: for it was Abbas who on that occasion first proposed the oath that may almost be called the basis of Islam. A critical study of Mohammed’s early dealings with the Arabians brings us to a similar conclusion.

Of the other stories collected by Koelle from Mussulman sources to prove this point, perhaps the most forcible is that of the discussion between the prophet, his uncle, Abu Tālib, under whose protection he was then living, and Abu Jahl. Abu Talib called his nephew and said to him, “Thou seest the nobles of thy people are assembled here to concede to thee certain things, and, in return, to receive concessions from thee.” Mohammed made this reply: “Well, then, give me a word whereby the Arabs may be governed and the Persians subjugated.” Abu Jahl responded to this request in the name of his fellow-elders by saying: “Thou shalt have ten words.” But Mohammed setting him right, and indicating what kind of word in his opinion could alone answer the purpose, rejoined: “Say, ‘There is no God except Allah!’ and renounce what you worship besides Him.” This story Koelle quotes from Ibn Ishāk, the earliest and most trustworthy biographer.

Certainly the movement from paganism to monotheism, which took place in Arabia in those days, was in itself a fine thing; and it was accompanied by much sincerity and religious zeal. It is also obvious that Mohammed possessed a personality peculiarly attractive to the Arabian, and that this, as well as his enthusiasm on the subject of his mission, had the effect of attracting many to the cause.

But not only did Mohammed pay much more regard to politics than can be possibly excused, he also accepted the religious and ethical teaching of the Hanifs only in the most superficial manner; and, under the cover of verbal conformity, retained as much as possible of the original pagan ideas in which he had been reared. The result is that his followers are still to be found possessed of what seems at first sight to be correct doctrine upon fundamentals, and yet are unable to advance by its assistance along the path of light and progress.

The popular idea, that fanatical intolerance of all professors of other religions is an essential and fundamental principle in Mohammedanism, cannot be maintained. The paganism of Mecca was distinctly latitudinarian, so Mohammed accepted in full the sacred books of the Jews and Christians, as would have seemed natural to an Arabian of that age, especially to a monotheistic teacher who was closely connected with the Ka’aba. This does not mean that he in any way apprehended the meaning of Judaism and Christianity. The doctrine of the perpetuity of the moral law never seems to have entered into his mind, even in the most elementary form. He wished to say that he had himself received a revelation superseding all former ones by the mandate of God, and he did not wish to make trouble by pronouncing other religions to be false, without absolute necessity. His real object was to unite the Arabs by a reformed religion, and at first he regarded his mission as a purely national one. Whatever were his ultimate designs upon the Jews and Christians in Arabia, he intentionally conveyed to them the impression that, if they recognised him as a prophet to others, he would be content without their accepting him themselves. Indeed, while he was still at Mecca, he was even uncertain whether the idolaters who accepted him might not be allowed to retain some of their idols as intermediaries between themselves and Allah. He went so far on one occasion as to actually effect a reconciliation on this basis; but as such a concession must have greatly damaged his influence with those who were favourably disposed to the Hanif movement, he afterwards repudiated the transaction, and declared that he had acted under the influence of the devil. His work in Mecca was not very successful; and the opposition he encountered was so strong that he had at last to begin to make attempts to start work in some other place, and he was finally successful in making a fresh beginning in Medina. Here he was able to take advantage of a family connection with some of the principal citizens, and also of a long-standing rivalry between Medina and Mecca. Although the movement in Mecca had not been widely successful, Mohammed had gathered amongst his followers several really prominent men. Consequently, the people of Medina, although divided on the subject of his prophetic mission, were unanimous as to the advisability of receiving him and his followers into their town. Settled in Medina, Mohammed’s fortunes underwent a change. The chieftancy of the tribe to which his grandmother had belonged fell vacant, and, as most of the members of this tribe had become Mussulmans, Mohammed had no difficulty in himself becoming their chief. Considering himself restrained by no preconception or former revelation of the moral law, he was able, without dropping for one moment his pretensions to prophethood, to use every means of fraud and violence which seemed conducive to his political end. As Koelle has pointed out, there is no reason to suppose that his principles in any way changed, but under the altered conditions and environment the utterly non-ethical theory of revelation held by the prophet became more apparent. This is perhaps most clearly brought out by his utterly unscrupulous dealing with the Jews, and also by the story of Zaid and Zainab, in all which affairs Mohammed professed himself to be acting under Divine direction, nor is it at all obvious that he did not actually believe it. Finally, before his death, he succeeded in establishing his religion and political system throughout the whole of Arabia.

Of course it was impossible for a movement like this to take place without rival prophets appearing in other parts of the country. Two of these appeared during Mohammed’s lifetime, and he thought it best to guard against future schisms of a similar kind by declaring himself the last of the prophets. Exactly what he meant by this is not very clear: if the almost universal voice of Islam is to be accepted, he did not mean that he was the last divinely appointed teacher, for all Mussulmans look forward to the coming of a Mehdi or Mahdi, who, together with Jesus, the son of Mary, is to appear in the last days, and spread the doctrines of Islam throughout the world. Orthodox Mussulmans, however, always look upon Mohammed as the last great sāhibi kitāb, or book-bearer.

The ordinary Sunnis, who are the largest and best-known Mussulman sect, assert that, as a matter of fact, since the time of Mohammed, no divinely-appointed teacher has as yet appeared. The Khalīfs were in their eyes simply appointed by the congregation, and the four great writers of the sunnat, which is to them the only authoritative commentary upon the doctrines of Islam, were only learned and saintly men. Now, they hold, these doctrines can only be learnt from this book, and from the Qurān itself; for the mujtahid or high mulla, capable of giving authoritative decisions on moot points, no longer exists.
