In the several heads of Mohammed’s doctrine there is practically nothing original. The Arabs of that time had outgrown their crude heathenism, and it was only by force of habit, without real attachment, that, a highly conservative people as they were, they held firmly by the ancient practices. In particular, isolated ideas originating in Christianity had become widely diffused through the agency of wandering bards. Very many Arabs were already Christians. Their Christianity, it is true, sat but loosely on them; for the finest elements of that religion they had no organ. Moreover, there were in Arabia many Jews who here also occasionally, as in Abyssinia, made numerous proselytes; but the rigid and irksome ordinances of Judaism were suited to the nature of the proud and untamed inhabitants of the Arabian desert as little as were the mystical doctrines and the too ideal ethics of Christianity. Mohammed borrowed from both religions, but especially from Judaism, those elements which instinct rather than reflection taught him to be suited to his countrymen. The main lines of his doctrine are a further development of Judaism, only simpler and coarser; speaking generally, it stands much nearer to the religion of the Old Testament than the Christianity of the Church does.
Mohammed’s idea of God is essentially that of the Old Testament, only he gives greater prominence to the divine omnipotence and arbitrary sovereignty, and less to the divine holiness. He attributes to God many human features, but these no longer have the naïve and poetic charm possessed by so many of the Old Testament anthropomorphisms. Everything is done and determined by God; man must submit himself blindly; whence the religion is called Islám (“surrender”), and its professor Muslim (“one who surrenders himself”). Mohammed had the strongest antipathy for the doctrines of the Trinity and the divine Sonship of Christ. True, his acquaintance with these dogmas was superficial, and even the clauses of the Creed that referred to them were not exactly known to him; but he rightly felt that it was quite impossible to bring them into harmony with simple genuine Semitic monotheism, and probably it was this consideration alone that hindered him from embracing Christianity.
According to the Koran, God makes known His will through prophets, of whom, in the course of time, He has sent many into the world. From Jesus down to the time of Mohammed, it was the duty of men to follow the former and His gospel; the Jews incurred grave sin by rejecting Him. Jesus was greater than all the prophets before Him; but the final revelation was first made known through Mohammed. The earlier sacred writings taught the same doctrine as the Koran, and bear witness to Mohammed; but they had been falsified by the Jews and the Christians. The laws which God laid down through the prophets are not necessarily in harmony with each other, for God changes His ordinances at will; even in the Koran itself He sometimes cancels commandments which He had previously laid down in that very book. Mohammed is but a frail mortal, only chosen of God. He is subject to sin, and without the gift of miracles bestowed on former prophets. This last limitation, which is clearly expressed in the Koran, was, as was to be expected, very soon explained away by his followers, and numerous miracles are accordingly related of him.
God rewards good and punishes evil deeds; only, He is merciful, and is easily propitiated by repentance. But the punishment of the impenitent wicked will be fearful. The horrors of hell are vividly presented; we can see how grievously the thought of them afflicted the Prophet himself. In accordance with Christian precedent, he conceives of hell as fire. In his description of the heavenly paradise, or “garden,” also, Mohammed appropriates representations from the Old and New Testaments, yet depicts its joys according to his own fancy. His picture of the glory of the saints above can be properly understood only when the reader remembers the barrenness of Mohammed’s native land and the exceedingly simple manner of life of his countrymen. The bright-eyed maidens who give their society to the righteous in paradise are the innovation of a sensual nature. The crude representations of hell and heaven took powerful hold of the Arab imagination, and unquestionably contributed much to the diffusion and establishment of Islam. Other eschatological imaginings, about the resurrection and the last judgment, have an important rôle in the Koran. All of them attach to older ideas, and particularly to such as had already been borrowed from the Persians by Judaism, and partly also by Christianity. Awe of the judgment day was perhaps the most important cause of Mohammed’s becoming a visionary and a prophet. The Koran has, of course, much to say of angels and devils. Alongside of these figure also demons or jinn, taken from Arab popular belief, but connected also with late Jewish notions. The minor contradictions that naturally occur in such myths and fancies have caused little difficulty to the ingenuity of interpreters, and still less to the simple faith of the masses.
The ethics of Islam are not so strict or earnest as those of Judaism. Mohammed, it is true, insists on virtuous disposition and action, and is energetic in his denunciations of vice: he urges honourable dealing, benevolence, placability, and so forth, and requires men ever to be mindful of God and of the retribution beyond the grave. But he is no rigorist. His very crass doctrine of retribution, which governs the rules of conduct, admits the application of commercial principles: the consequences of sins can be averted by certain penances; under certain circumstances one can rid oneself of the duty of fulfilling an obligation, and even perjury can be made up for by good works. In dire necessity even the faith may be denied in words (contrast Matt. x. 32, 33); against making a free use of this permission, Mohammedans have, it is true, been protected by their pride and the strength of their conviction. Islam is a thoroughly practical religion, which does not make it necessary to explain away too high demands (such as those of Matt. v. 33-41) by artificial interpretations. The Koran also has comfort for the persecuted and the suffering; but it is too Arab—or, shall we say, too natural and too manly?—to declare the poor and oppressed to be in themselves happy. The Koran, further, pronounces all earthly things to be indeed vain; yet it takes much account of human wants and desires, and lays down definite regulations about property and goods. If the Prophet had immediately met with recognition in his native town, he might perhaps have founded a contemplative monkish community; but, driven by necessity to become the ruler of a warrior State, he had to follow another course. After some hesitation he finally preached war against unbelievers as such; they have no choice but between acceptance of Islam and extermination. Only to the professors of old religions of revelation, that is to say, in the first instance, to Jews and Christians, does it remain lawful to live on as subjects on payment of tribute. The Moslem’s vocation, alike in this and in the future life, is to rule the world.
Islam has no mystical sacraments, although it has a number of external observances. Originally Mohammed himself had attached the greatest value to severe exercises of penance, such as watching and fasting; gradually he relaxed much both to himself and to his followers, but an Oriental religion wholly without mortifications of this kind is quite unthinkable. Accordingly he made fasting in the month of Ramadán obligatory in the sense that throughout the entire month, as long as the sun is above the horizon, both eating and drinking are absolutely forbidden. In Oriental heat this is a severe burden, and one can readily believe that in the month of the fast, towards the end of the day, the majority of the faithful are thinking much more about the enjoyments of the coming night than about God and the hereafter. Still more important than fasting is the salát. As with all Oriental Christians a certain number of daily prayers are prescribed to the clergy, and partly also to the laity, so Mohammed again, after some hesitation, finally fixed for all believers that there should be five daily “prayers.” This salát is essentially different from what we call prayer. It consists in a fixed series of bowings, prostrations, and other attitudes, accompanied by the recitation of certain religious formulæ. Of course the worshipper is not forbidden at other times or in other ways to call upon God in words of his own; but to do so is not the official and obligatory action. Prayer is preceded by an ablution; when water, a commodity of such rarity in Arabia, is wanting, rubbing with sand can be substituted.[[14]] It is more meritorious to take part in the public salát of the community, conducted by a leader (Imám), than to discharge the salát by oneself. Public attendance ought to be given, in particular, on Friday, which is especially set apart for public worship, but in other respects is regarded as a working day: the Sabbath rest is unknown to Islam. The common prayer and its formalities have done much to give stability to Islam. The multitudes, while doing what was indispensable for the salvation of their souls, became trained to the habit of strictly following a leader. As Von Kremer has pointed out, the mosque was the drill ground for the warlike believers of early Islam.
A noteworthy survival of Arab heathenism is the pilgrimage to Mecca. In Mohammed’s native town there was a temple called the Caaba (“the die”), with an object of ancient veneration, “the black stone.” This sanctuary had gradually come to be the centre of pilgrimage for the greater part of Arabia. In connection with this a lively trade was developed, which must have been very advantageous to the inhabitants of Mecca, the Koraish. Still more important for these was the circumstance that their whole territory was held to be holy and inviolable, and that they had the most favourable opportunities for entering into friendly relations with the various Bedouin tribes. They were thus able to maintain a caravan traffic with the old lands of civilisation beyond the desert and its predatory nomads. In this way they not only became prosperous, but also gained a great intellectual superiority over the other Arabs. As a man of Koraish, Mohammed himself had grown up in pious reverence for the Caaba and the black stone. Properly speaking, indeed, this reverence was at variance with the principles of his religion; but he managed to adjust matters by his theory that these holy things had been established by Abraham, and only abused by the heathen. Possibly in this view he was but following some Meccan predecessor whom Jews or Christians had told about Abraham and Ishmael. The heathen of Mecca, of course, knew nothing about these or any other characters of the Old Testament. That the retention of this sanctuary on Mohammed’s part was due less to calculation than to deeply rooted religious habit, seems to be shown by this, among other things, that between his emigration and the capture of Mecca, he frequently expressed his sorrow at being excluded from free participation in the ceremonies there. When at last he made his entry as a conqueror, he did away with all the open signs of idolatry, and in his last Pilgrimage, shortly before his death, he finally fixed the observances—some of them very peculiar—to be followed. Everything heathenish was to disappear; or, if various things of that nature remained, they were uncomprehended, and therefore inoffensive. Yet one rock of offence was unremoved—the veneration of the old fetish—the black stone, a veneration to which some consistent Moslems could only reluctantly bring themselves, and which in later times is occasionally even scoffed at by less steadfast believers. In strictness it is the duty of every Moslem to take part in the yearly pilgrimage as often as he can; but it is not contrary to the intention of Mohammed (who was always ready to take account of practical difficulties), if the proviso “as he can” is strongly accentuated in practice, and thus comparatively few join in the expedition from the more distant lands of Mohammedanism. With all this the pilgrimage has been a chief pillar of Islam. In Mecca the most pious Moslems still meet from year to year out of regions so remote as Turkestan, British and Dutch India, the Turkish dominions, Morocco, and Nigritia, and exchange ideas and prejudices; a custom which naturally helps to maintain the unity of the faith. What is of particular importance is that many of the most zealous and learned pilgrims stay permanently in Mecca, and from this centre labour to promote the pure faith, and hostility against all idolaters (Europeans in particular).
Another relic of rude heathenism handed down from hoary antiquity is circumcision. It is not specially enjoined in the Koran, but is taken for granted as being the custom with all Arabs. It is not, however, theoretically at least, an integral part of religion, as it is in Judaism.
Like the Jews, Mohammed puts a high value upon alms. Gradually, however, he changed the freewill offering of love into a formal and somewhat heavy tax, out of which not only were the poor supported, but also the expenses of government were met.
Mohammed’s laws relating to food are not nearly so complicated as those of the Jews. The animals of which the Moslem, whether by Mohammed’s injunction or by some later rule, may not eat are mostly such as men are naturally averse to (e.g. carnivora). Only the pig and the dog are wholly unclean. Moreover, it is lawful to eat only of such animals as have been duly slaughtered with the formula: “In the name of God, the compassionate Compassioner.” The Moslem, like the Jew, and, strictly speaking, the Christian also (Acts xv. 20, 29, xxi. 25), is enjoined to abstain from blood. But, in danger of death by starvation, he is permitted the use of any food. Wine is interdicted; and under this name the legislature meant to include all intoxicating drinks. No impartial observer will deny that this regulation, much as it has been broken, has proved a real blessing to all the lands of Islam. It is not certain whether the prohibition of a favourite Arab game of chance (meisir), in which pointless arrows were used as lots, is intended to include all forms of gambling; perhaps Mohammed had in view only the heathenish practices, or the wastefulness, that used to be associated with the meisir.
