Quran 7:22 — The Purgatory (Al-A'araf)

He thus duped them with lies. As soon as they tasted the tree, their bodies became visible to them, and they tried to cover themselves with the leaves of Paradise. Their Lord called upon them: "Did I not enjoin you from that tree, and warn you that the devil is your most ardent enemy?"

[7:21] He swore to them, "I am giving you good advice."

[7:23] They said, "Our Lord, we have wronged our souls, and unless You forgive us and have mercy on us, we will be losers."
