Quran 7:76 — The Purgatory (Al-A'araf)

The arrogant ones said, "We disbelieve in what you believe in."

[7:75] The arrogant leaders among his people said to the common people who believed, "How do you know that Sãleh is sent by his Lord?" They said, "The message he brought has made us believers."

[7:77] Subsequently, they slaughtered the camel, rebelled against their Lord's command, and said, "O Sãleh, bring the doom you threaten us with, if you are really a messenger."
