For in God's sight are (all) his servants, (namely), those who say: 'Our Lord, we have indeed believed: forgive us, then, our sins ("dhunub"), and save us from the agony of the Fire.' — Quran 3: 15–16 This use of dhanb in the Quran exemplifies that this type of sin is punishable in the afterlife.
(Ayat:14-15) Orang-orang yang berdo'a: "Wahai Tuhan kami, sungguh kami telah beriman, maka kiranya ampuni segala dosa kami, serta hindarkan kami terhadap Azab Neraka," golongan yang bersabar, golongan yang benar, golongan yang tetap taat, golongan yang berinfaq, serta golongan yang memohon pengampunan di permulaan pagi.
