Quran 2:81 — The Heifer (Al-Baqarah)

Indeed, those who earn sins and become surrounded by their evil work will be the dwellers of Hell; they abide in it forever.

[2:80] Some have said, "Hell will not touch us, except for a limited number of days." Say, "Have you taken such a pledge from GOD—GOD never breaks His pledge—or, are you saying about GOD what you do not know?"

[2:82] As for those who believe, and lead a righteous life, they will be the dwellers of Paradise; they abide in it forever.
