وَلَيسَتِ التَّوبَةُ لِلَّذينَ يَعمَلونَ السَّيِّئَاتِ حَتّىٰ إِذا حَضَرَ أَحَدَهُمُ المَوتُ قالَ إِنّي تُبتُ الآنَ وَلَا الَّذينَ يَموتونَ وَهُم كُفّارٌ ۚ أُولـٰئِكَ أَعتَدنا لَهُم عَذابًا أَليمًا

But repentance is not [accepted] of those who [continue to] do evil deeds up until, when death comes to one of them, he says, "Indeed, I have repented now," or of those who die while they are disbelievers. For them We have prepared a painful punishment.
