Quran 7:167 — The Purgatory (Al-A'araf)

Additionally, your Lord has decreed that He will raise up against them people who will inflict severe persecution upon them, until the Day of Resurrection. Your Lord is most efficient in enforcing retribution, and He is certainly the Forgiver, Most Merciful.

[7:166] When they continued to defy the commandments, we said to them, "Be you despicable apes."

[7:168] We scattered them among many communities throughout the land. Some of them were righteous, and some were less than righteous. We tested them with prosperity and hardship, that they may return.
