The word ‘mystic,’ which has passed from Greek religion into European literature, is represented in Arabic, Persian, and Turkish, the three chief languages of Islam, by ‘Sūfī.’ The terms, however, are not precisely synonymous, for ‘Sūfī’ has a specific religious connotation, and is restricted by usage to those mystics who profess the Mohammedan faith. And the Arabic word, although in course of time it appropriated the high significance of the Greek—lips sealed by holy mysteries, eyes closed in visionary rapture—bore a humbler meaning when it first gained currency (about 800 A.D.). Until recently its derivation was in dispute. Most Sūfīs, flying in the face of etymology, have derived it from an Arabic root which conveys the notion of ‘purity’; this would make ‘Sūfī’ mean ‘one who is pure in heart’ or ‘one of the elect.’ Some European scholars identified it with σοφός in the sense of ‘theosophist.’ But Nöldeke, in an article written twenty years ago, showed conclusively that the name was derived from sūf (wool), and was originally applied to those Moslem ascetics who, in imitation of Christian hermits, clad themselves in coarse woollen garb as a sign of penitence and renunciation of worldly vanities.

The earliest Sūfīs were, in fact, ascetics and quietists rather than mystics. An overwhelming consciousness of sin, combined with a dread—which it is hard for us to realise—of Judgment Day and the torments of Hell-fire, so vividly painted in the Koran, drove them to seek salvation in flight from the world. On the other hand, the Koran warned them that salvation depended entirely on the inscrutable will of Allah, who guides aright the good and leads astray the wicked. Their fate was inscribed on the eternal tables of His providence, nothing could alter it. Only this was sure, that if they were destined to be saved by fasting and praying and pious works—then they would be saved. Such a belief ends naturally in quietism, complete and unquestioning submission to the divine will, an attitude characteristic of Sūfism in its oldest form. The mainspring of Moslem religious life during the eighth century was fear—fear of God, fear of Hell, fear of death, fear of sin—but the opposite motive had already begun to make its influence felt, and produced in the saintly woman Rābiʿa at least one conspicuous example of truly mystical self-abandonment.

So far, there was no great difference between the Sūfī and the orthodox Mohammedan zealot, except that the Sūfīs attached extraordinary importance to certain Koranic doctrines, and developed them at the expense of others which many Moslems might consider equally essential. It must also be allowed that the ascetic movement was inspired by Christian ideals, and contrasted sharply with the active and pleasure-loving spirit of Islam. In a famous sentence the Prophet denounced monkish austerities and bade his people devote themselves to the holy war against unbelievers; and he gave, as is well known, the most convincing testimony in favour of marriage. Although his condemnation of celibacy did not remain without effect, the conquest of Persia, Syria, and Egypt by his successors brought the Moslems into contact with ideas which profoundly modified their outlook on life and religion. European readers of the Koran cannot fail to be struck by its author’s vacillation and inconsistency in dealing with the greatest problems. He himself was not aware of these contradictions, nor were they a stumbling-block to his devout followers, whose simple faith accepted the Koran as the Word of God. But the rift was there, and soon produced far-reaching results.

Hence arose the Murjites, who set faith above works and emphasised the divine love and goodness; the Qadarites who affirmed, and the Jabarites who denied, that men are responsible for their actions; the Muʿtazilites, who built a theology on the basis of reason, rejecting the qualities of Allah as incompatible with His unity, and predestinarianism as contrary to His justice; and finally the Ashʿarites, the scholastic theologians of Islam, who formulated the rigid metaphysical and doctrinal system that underlies the creed of orthodox Mohammedans at the present time. All these speculations, influenced as they were by Greek theology and philosophy, reacted powerfully upon Sūfism. Early in the third century of the Hegira—the ninth after Christ—we find manifest signs of the new leaven stirring within it. Not that Sūfīs ceased to mortify the flesh and take pride in their poverty, but they now began to regard asceticism as only the first stage of a long journey, the preliminary training for a larger spiritual life than the mere ascetic is able to conceive. The nature of the change may be illustrated by quoting a few sentences which have come down to us from the mystics of this period.

“Love is not to be learned from men: it is one of God’s gifts and comes of His grace.”

“None refrains from the lusts of this world save him in whose heart there is a light that keeps him always busied with the next world.”

“When the gnostic’s spiritual eye is opened, his bodily eye is shut: he sees nothing but God.”

“If gnosis were to take visible shape all who looked thereon would die at the sight of its beauty and loveliness and goodness and grace, and every brightness would become dark beside the splendour thereof.”[2]

“Gnosis is nearer to silence than to speech.”

“When the heart weeps because it has lost, the spirit laughs because it has found.”
