Quran 18:35 — The Cave (Al-Kahf)

When he entered his garden, he wronged his soul by saying, "I do not think that this will ever end.

[18:34] Once, after harvesting, he boastfully told his friend: "I am far more prosperous than you, and I command more respect from the people."

[18:36] "Moreover, I think this is it; I do not think that the Hour (the Hereafter) will ever come to pass. Even if I am returned to my Lord, I will (be clever enough to) possess an even better one over there."
