Quran 10:38 — Jonah (Younus)

If they say, "He fabricated it," say, "Then produce one sura like these, and invite whomever you wish, other than GOD, if you are truthful."

[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.

[10:39] Indeed, they have rejected this without studying and examining it, and before understanding it. Thus did those before them disbelieve. Therefore, note the consequences for the transgressors.
