Quran 46:21 — The Dunes (Al-Ahqaf)

وَاذكُر أَخا عادٍ إِذ أَنذَرَ قَومَهُ بِالأَحقافِ وَقَد خَلَتِ النُّذُرُ مِن بَينِ يَدَيهِ وَمِن خَلفِهِ أَلّا تَعبُدوا إِلَّا اللَّهَ إِنّى أَخافُ عَلَيكُم عَذابَ يَومٍ عَظيمٍ

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."
