Quran 66:9 — Prohibition (Al-Tahreem)

O prophet, struggle against the disbelievers and the hypocrites and be stern with them. Their abode is Gehenna, and a miserable destiny.

[66:8] O you who believe, you shall repent to GOD a firm repentance. Your Lord will then remit your sins and admit you into gardens with flowing streams. On that day, GOD will not disappoint the prophet and those who believed with him. Their light will radiate in front of them and to their right. They will say, "Our Lord, perfect our light for us, and forgive us; You are Omnipotent."

[66:10] GOD cites as examples of those who disbelieved the wife of Noah and the wife of Lot. They were married to two of our righteous servants, but they betrayed them and, consequently, they could not help them at all against GOD. The two of them were told, "Enter the Hellfire with those who deserved it."
