Quran 7:21 — The Purgatory (Al-A'araf)

He swore to them, "I am giving you good advice."

[7:20] The devil whispered to them, in order to reveal their bodies, which were invisible to them. He said, "Your Lord did not forbid you from this tree, except to prevent you from becoming angels, and from attaining eternal existence."

[7:22] 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?"
