Quran 7:161 — The Purgatory (Al-A'araf)

Recall that they were told, "Go into this town to live, and eat therefrom as you please, treat the people amicably, and enter the gate humbly. We will then forgive your transgressions. We will multiply the reward for the righteous."

[7:160] We divided them into twelve tribal communities, and we inspired Moses when his people asked him for water: "Strike the rock with your staff," whereupon twelve springs gushed out therefrom. Thus, each community knew its water. And we shaded them with clouds, and sent down to them manna and quails: "Eat from the good things we provided for you." It is not us that they wronged; it is they who wronged their own souls.

[7:162] But the evil ones among them substituted other commands for the commands given to them. Consequently, we sent upon them condemnation from the sky, because of their wickedness.
