Quran 3:88 — The Amramites (Ali-'Imran)

Eternally they abide therein; the retribution is never commuted for them, nor will they be reprieved.

[3:87] These have incurred condemnation by GOD, and the angels, and all the people.

[3:89] Exempted are those who repent thereafter, and reform. GOD is Forgiver, Most Merciful.
