Not acceptable is the repentance of those who commit sins until death comes to them, then say, “Now I repent.” Nor is it acceptable from those who die as disbelievers. For these, we have prepared a painful retribution.
وَلَيسَتِ التَّوبَةُ لِلَّذينَ يَعمَلونَ السَّيِّـٔاتِ حَتّىٰ إِذا حَضَرَ أَحَدَهُمُ المَوتُ قالَ إِنّى تُبتُ الـٰٔنَ وَلَا الَّذينَ يَموتونَ وَهُم كُفّارٌ أُولٰئِكَ أَعتَدنا لَهُم عَذابًا أَليمًا
