Quran 18:8 — The Cave (Al-Kahf)

Inevitably, we will wipe out everything on it, leaving it completely barren.*

[18:7] We have adorned everything on earth, in order to test them, and thus distinguish those among them who work righteousness.

[18:9] Why else do you think we are telling you about the people of the cave, and the numbers connected with them? They are among our wondrous signs.
