From True Belief to the Proof of the Existence and Uniqueness of the True Believer and the Qur’an as His Revelation
1.) True belief exists. Because the claim “True belief does not exist” refutes itself. If the negation of a proposition is contradictory, then that proposition is true.
2.) True belief exists through true believing, and true believing exists through a true believer. In other words, a true believer exists.
3.) A true believer never makes a mistake in any of his beliefs. A true believer correctly believes every true proposition that exists, because if there were a true proposition that he did not correctly believe, he could not be considered a true believer. Therefore, his beliefs concerning events and facts that exist within time and space—from the movement of photons to the movement of galaxies—are also true. However, only one who encompasses and observes time and space can be infallible in his beliefs concerning events and facts and correctly believe every true proposition. Furthermore, a being that exists within time and space is itself temporally limited and therefore cannot eternally hold true beliefs about realities that exist throughout all time.
4.) The one who encompasses space is unique, because he encompasses it from every direction. He is exalted because he transcends space. Since he encompasses space in its entirety and transcends it, and since he alone possesses supreme greatness beyond space, his greatness is infinite.
5.) Throughout history, the Qur'an is the only source that consistently and without contradiction describes a true believer who is unique, all-encompassing, exalted, and infinite in greatness. This constitutes evidence that the Qur'an was revealed to humanity by the True believer.
