Quran 40:83 — Forgiver (Ghafer)

When their messengers went to them with clear proofs, they rejoiced in the knowledge they had inherited, and the very things they ridiculed were the cause of their fall.

[40:82] Have they not roamed the earth and noted the consequences for those who preceded them? They used to be greater in number, greater in power, and possessed a greater legacy on earth. Yet, all their achievements did not help them in the least.

[40:84] Subsequently, when they saw our retribution they said, "Now we believe in GOD ALONE, and we now disbelieve in the idol worship that we used to practice."
