Quran 7:65 — The Purgatory (Al-A'araf)

To 'Ãd we sent their brother Hûd. He said, "O my people, worship GOD; you have no other god beside Him. Would you then observe righteousness?"

[7:64] They rejected him. Consequently, we saved him and those with him in the ark, and we drowned those who rejected our revelations; they were blind.

[7:66] The leaders who disbelieved among his people said, "We see that you are behaving foolishly, and we think that you are a liar."
