Quran 7:59 — The Purgatory (Al-A'araf)

We sent Noah to his people, saying, "O my people, worship GOD; you have no other god beside Him. I fear for you the retribution of an awesome day."

[7:58] The good land readily produces its plants by the leave of its Lord, while the bad land barely produces anything useful. We thus explain the revelations for people who are appreciative.

[7:60] The leaders among his people said, "We see that you are far astray."
