“God reveals the truth behind the languages of the Quran to those whom He loves and who are true Sufis.”

The Spiritual Message of Hazrat Inayat Khan
Context: What is a Sufi? Strictly speaking, every seeker after the ultimate truth is really a Sufi, whether he calls himself that or not. But as he seeks truth according to his own particular point of view, he often finds it difficult to believe that others, from their different points of view, are yet seeking the same truth, and always with success, though to a varying degree. That is in fact the point of view of the Sufi and it differs from others only in its constant endeavor to comprehend all others as within itself. It seeks to realize that every person, following his own particular line in life, nevertheless fits into the scheme of the whole and finally attains not only his own goal, but the one final goal of all.
Hence every person can be called a Sufi either as long as he is seeking to understand life, or as soon as he is willing to believe that every other human being will also find and touch the same ideal. When a person opposes or hinders the expression of a great ideal, and is unwilling to believe that he will meet his fellow men as soon as he has penetrated deeply enough into every soul, he is preventing himself from realizing the unlimited. All beliefs are simply degrees of clearness of vision. All are part of one ocean of truth. The more this is realized the easier is it to see the true relationship between all beliefs, and the wider does the vision of the one great ocean become.

Letter to the Grand Duchess Christina (1615)
Context: The passage of time has revealed to everyone the truths that I previously set forth; and, together with the truth of the facts, there has come to light the great difference in attitude between those who simply and dispassionately refused to admit the discoveries to be true, and those who combined with their incredulity some reckless passion of their own. Men who were well grounded in astronomical and physical science were persuaded as soon as they received my first message. There were others who denied them or remained in doubt only because of their novel and unexpected character, and because they had not yet had the opportunity to see for themselves. These men have by degrees come to be satisfied. But some, besides allegiance to their original error, possess I know not what fanciful interest in remaining hostile not so much toward the things in question as toward their discoverer. No longer being able to deny them, these men now take refuge in obstinate silence, but being more than ever exasperated by that which has pacified and quieted other men, they divert their thoughts to other fancies and seek new ways to damage me.<!-- ¶4
