Quran 10:36 — Jonah (Younus)

Most of them follow nothing but conjecture, and conjecture is no substitute for the truth. GOD is fully aware of everything they do.

[10:35] Say, "Does any of your idols guide to the truth?" Say, "GOD guides to the truth. Is one who guides to the truth more worthy of being followed, or one who does not guide, and needs guidance for himself? What is wrong with your judgment?"

[10:37] This Quran could not possibly be authored by other than GOD. It confirms all previous messages, and provides a fully detailed scripture. It is infallible, for it comes from the Lord of the universe.
