"Fourthly: Also, if the Qur'an is supposed to be the word of man, it necessitates imagining to be its opposite a book which has self-evidently guided the purified, veracious saints and spiritual poles, who shine like stars in the heavens of the world of mankind, has continuously instructed every level of the people of perfection in truth and justice, veracity and fidelity, faith and trustworthiness, and has ensured the happiness of the two worlds through the truths of the pillars of belief and the principles of the pillars of Islam, and through the testimony of these achievements is of necessity veracious, and pure, genuine truth, and absolutely right, and most serious — it necessitates imagining, God forbid, that this Book comprises the opposites of these qualities, effects, and lights. And that, regarding it as a collection of fabrications and lies, it is a frenzy of unbelief that would shame even the Sophists and the devils, and cause them to tremble.

"And this impossibility necessitates the further most ugly and abhorrent impossibility that One who, according to the testimony of the religion and Shari'a of Islam which he proclaimed, and the unanimous indications to the extraordinary fear of God and pure and sincere worship which he demonstrated throughout his life, and as necessitated by the good moral qualities unanimously witnessed in him, and according to the affirmation of the people of truth and perfection whom he reared, was the most believing, the most steadfast, the most trustworthy, and the most truthful, was —God forbid, and again, God forbid— without belief, that he was most untrustworthy, did not fear God, nor shrink from lying. To imagine this necessitates imagining the most loathsome form of impossibility and perpetrating the most iniquitous and vicious sort of misguidance.

"In Short: As is stated in the Eighteenth Sign of the Nineteenth Letter, the common people, whose understanding of the Qur'an is gained by listening to it, say, 'Were the Qur'an to be compared with all the books I have listened to and the other books in the world, it would not resemble any of them; it is not of the same sort as them nor or the same degree.' The Qur'an, then, is of a degree either above all of them or below all of them. To be below them is impossible, and no enemy nor the Devil even could accept it. In which case, the Qur'an is above all other books, and is therefore a miracle. In just the same way, we say according to the categorical proof called 'residue', taken from the sciences of method and logic:

"O Satan and O disciples of Satan! The Qur'an is either the Word of God come from the Supreme Throne of God and His Greatest Name, or, God forbid, and again, God forbid, it is a human forgery fabricated on earth by someone without belief who neither feared God nor knew Him. In the face of the above proofs, O Satan, you can neither say that, nor could you have said it, nor will you be able to say it in the future. Therefore, the Qur'an is the Word of the Creator of the universe. Because there is no point between the two; it is impossible and precluded that there should be. Just as we have proved in the most clear and decisive manner; and you have seen it and heard it.
