Surah 69. Al-Haqqah, Ayah 38

This is an adjuration in the same form as that which occurs in lvi. 75, lxx. 40, xc. 1, and elsewhere. Allah's Word is the quintessence of Truth. But what if someone doubts whether a particular Message is Allah's Word comunicated through His Messenger, or merely an imaginary tale presented by a poet, or a soothsayer's vain prophecy? Then we have to exanmine it in the light of our highest spiritual facilities. The witness to that Word is what we know in the visible world, in which falsehood in the long run gives place to truth, and what we know in the invisible world, through our highest spiritual faculties. We are asked to examine and test it in both these ways.
