The Qur'an, set on a shelf with other books, has a function entirely different to theirs and exists in a different dimension. It moves an illiterate shepherd to tears when recited to him, and it has shaped the lives of millions of simple people over the course of almost fourteen centuries; it has nourished some of the most powerful intellects known to the human record; it has stopped sophisticates in their tracks and made saints of them, and it has been the source of the most subtle philosophy and of an art which expresses its deepest meaning in visual terms; it has brought the wandering tribes of mankind together in communities and civilizations upon which its imprint is apparent even to the most casual observer.

In all fairness the Qur'an is a wonder. Its short suras of the Meccan period are charged with expressive force and persuasive power. Its style has no precedent in the Arabic language. Its effusion from the tongue of an illiterate man with no education, let alone literary training, is a phenomenon which, in this respect, can justifiably be described as a miracle.

The Qurān is one of the world’s classics which cannot be translated without grave loss. It has a rhythm of peculiar beauty and a cadence that charms the ear. Many Christian Arabs speak of its style with warm admiration, and most Arabists acknowledge its excellence… indeed it may be affirmed that within the literature of the Arabs, wide and fecund as it is both in poetry and in elevated prose, there is nothing to compare with it.

The Qur'an is not a book of abstract theories and cold ideas, which one can grasp while seated in a cozy armchair. Nor is it merely a religious book like other religious books, whose meanings can be grasped in seminaries and oratories. On the contrary, it is a Book which contains a message, an invitation, which generates a movement. The moment it began to be sent down, it impelled a quiet and pious man to abandon his life of solitude and confront the world that was living in rebellion against Allah. It inspired him to raise his voice against falsehood, and pitted him in a grim struggle against the lords of disbelief, evil and iniquity. One after the other, from every home, it drew every pure and noble soul, and gathered them under the banner of truth. In every part of the country, it made all the mischievous and the corrupt to rise and wage war against the bearers of the truth.

Its highest degree of eloquence, which is beyond the capacity of a human being. However, since we come after the first Arabs we are unable to reach its essence. But the measure which we know is that the employment of lucid words and sweet constructions gracefully and without affectation that we find in the Tremendous Qur’an is to be found nowhere else in any of the poetry of the earlier or later peoples.

On the whole, while many parts of the Koran undoubtedly have considerable rhetorical power, even over an unbelieving reader, the book, æsthetically considered, is by no means a first-rate performance... Mohammed, in short, is not in any sense a master of style. This opinion will be endorsed by any European who reads through the book with an impartial spirit and some knowledge of the language, without taking into account the tiresome effect of its endless iterations. But in the ears of every pious Moslem such a judgment will sound almost as shocking as downright atheism or polytheism. Among the Moslems, the Koran has always been looked on as the most perfect model of style and language. This feature of it is in their dogmatic the greatest of all miracles, the incontestable proof of its divine origin. Such a view on the part of men who knew Arabic infinitely better than the most accomplished European Arabist will ever do, may well startle us. In fact, the Koran boldly challenged its opponents to produce ten súras, or even a single one, like those of the sacred book, and they never did so. That, to be sure, on calm reflection, is not so very surprising. Revelations of the kind which Mohammed uttered, no unbeliever could produce without making himself a laughing-stock.

The goal and intent of the book of the Qur'an, is not only not to detract from God the creator or from Christ or from God's prophets and envoys or from the divine books of the Testament, the Psalter, and the Gospel, but also to give glory to God the Creator, to praise and bear witness to Christ (the son of the Virgin Mary) above all prophets, and to confirm and approve of the Testament and the Gospel. When one reads the Qur'an with this understanding, assuredly some fruit can be elicited from it

I must say, it [the Koran] is as toilsome reading as I ever undertook. A wearisome confused jumble, crude, incondite; endless iterations, long-windedness, entanglement; most crude, incondite; — insupportable stupidity, in short! Nothing but a sense of duty could carry any European through the Koran ... It is the confused ferment of a great rude human soul; rude, untutored, that cannot even read; but fervent, earnest, struggling vehemently to utter itself in words ... We said "stupid:" yet natural stupidity is by no means the character of Mahomet's Book; it is natural uncultivation rather. The man has not studied speaking; in the haste and pressure of continual fighting, has not time to mature himself into fit speech ... The man was an uncultured semi-barbarous Son of Nature, much of the Bedouin still clinging to him: we must take him for that. But for a wretched Simulacrum, a hungry Impostor without eyes or heart ... we will not and cannot take him. Sincerity, in all senses, seems to me the merit of the Koran; what had rendered it precious to the wild Arab men ... Curiously, through these incondite masses of tradition, vituperation, complaint, ejaculation in the Koran, a vein of true direct insight, of what we might almost call poetry, is found straggling.

The Koran calls for belief and consequent obedience. It is, surely, calculated to inspire fear, indeed abject terror, rather than love.

Islam, more than any other religion human beings have devised, has all the makings of a thoroughgoing cult of death.....As a matter of doctrine, the Muslim conception of tolerance is one in which non-Muslims have been politically and economically subdued, converted, or put to sword.....Yes, the Bible contains its own sadistic lunacy—but the above [Qur'an] quotations [taken from The End of Faith, pp. 117-123] can be fairly said to convey the central message of the Qur’an—and of Islam at nearly every moment in its history. The Qur’an does not contain anything like a Sermon on the Mount. Nor is it a vast and self-contradictory book like the Old Testament, in which whole sections (like Leviticus and Deuteronomy) can be easily ignored and forgotten. The result is a unified message of triumphalism, otherworldliness, and religious hatred that has become a problem for the entire world. And the world still waits for moderate Muslims to speak honestly about it.

For Muslims the Quran is the Word of God; it is sacred scripture, not a work of "literature," a manual of law, or a text of theology, philosophy or history although it is of incomparable literary quality, contains many injunctions about a Sacred Law, is replete with verses of metaphysical, theological, and philosophical significance, and contains many accounts of sacred history. The unique structure of the Quran and the flow of its content constitute a particular challenge to most modern readers. For traditional Muslims the Quran is not a typical "read" or manual to be studied. For most of them, the most fruitful way of interacting with the Quran is not to sit down and read the Sacred Tex from cover to cover (although there are exceptions, such as completing the whole text during Ramadan). it is, rather, to recite a section with full awareness of it as the Word of God and to meditate upon it as one whose soul is being directly addressed, as the Prophet's soul was addressed during its revelation. ... In this context it must be remembered that the Quran itself speaks constantly of the Origin and the Return, of all things coming from God and returning to Him, who himself has no origin or end. As the Word of god, the Quran also seems to have no beginning and no end. Certain turns of phrase and teachings about the Divine Reality, the human condition, the life of this world, and the Hereafter are often repeated, but they are not mere repetitions. Rather each iteration of a particular word, phrase, or verse opens the door of a hidden passage to other parts of the Quran. Each coda is always a prelude to an as yet undiscovered truth.

The Koran is an inspiration for intolerance, murder and terror.

Consider the Koran, for example; this wretched book was sufficient to start a world-religion, to satisfy the metaphysical needs of countless millions for twelve hundred years, to become the basis of their morality and of a remarkable contempt for death, and also to inspire them to bloody wars and the most extensive conquests. Much may be lost in translation, but I have not been able to discover in it one single idea of value.

The superiority of the Qur'an over the rest of words, is like the superiority of Allah over His creations.
