Quran 46:12 — The Dunes (Al-Ahqaf)

Before this, the book of Moses provided guidance and mercy. This too is a scripture that confirms, in Arabic, to warn those who transgressed, and to give good news to the righteous.

[46:11] Those who disbelieved said about those who believed, "If it were anything good, they would not have accepted it before us." Because they were not guided to it, they said, "This is an old fabrication!"

[46:13] Surely, those who say, "Our Lord is GOD," then lead a righteous life, will have no fear, nor will they grieve.
