Quran 46:22 — The Dunes (Al-Ahqaf)

They said, "Did you come to divert us from our gods? We challenge you to bring (the retribution) you threaten, if you are truthful."

[46:21] Recall that the brother of 'Ãd warned his people at the dunes—numerous warnings were also delivered before him and after him: "You shall not worship except GOD. I fear for you the retribution of a great day."

[46:23] He said, "The knowledge about this is with GOD; I only deliver to you what I was sent to deliver. However, I see that you people are ignorant."
