Quran 46:21 — The Dunes (Al-Ahqaf)

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."

[46:20] The day will come when those who disbelieved will be introduced to the hellfire: "You have wasted the good chances given to you during your worldly life, and you rejoiced in them. Consequently, today you incur a shameful retribution as a requital for the arrogance you committed on earth without any basis, and for your evil works."

[46:22] They said, "Did you come to divert us from our gods? We challenge you to bring (the retribution) you threaten, if you are truthful."
