4:18

وَلَيْسَتِ التَّوْبَةُ لِلَّذِينَ يَعْمَلُونَ السَّيِّئَاتِ حَتَّىٰ إِذَا حَضَرَ أَحَدَهُمُ الْمَوْتُ قَالَ إِنِّي تُبْتُ الْآنَ وَلَا الَّذِينَ يَمُوتُونَ وَهُمْ كُفَّارٌ أُولَٰئِكَ أَعْتَدْنَا لَهُمْ عَذَابًا أَلِيمًا

Transliteration:

Walaysati alttawbatu lillatheena yaAAmaloona alssayyi-ati hatta itha hadara ahadahumu almawtu qala innee tubtu al-ana wala allatheena yamootoona wahum kuffarun ola-ika aAAtadna lahum AAathaban aleeman

Word by Word:

And not (is) the acceptance of repentance for those who do the evil deeds until when approaches one of them [the] death, he says, "Indeed I repent now;" and not those who die while they (are) disbelievers. Those - We have prepared for them a punishment painful.

Translations:

whereas repentance shall not be accepted from those who do evil deeds until their dying hour and then say, "Behold, I now repent"; nor from those who die as deniers of the truth: it is these for whom We have readied grievous suffering.

Of no effect is the repentance of those who continue to do evil, until death faces one of them, and he says, "Now have I repented indeed;" nor of those who die rejecting Faith: for them have We prepared a punishment most grievous.

The forgiveness is not for those who do ill-deeds until, when death attendeth upon one of them, he saith: Lo! I repent now; nor yet for those who die while they are disbelievers. For such We have prepared a painful doom.

And repentance is not for those who go on doing evil deeds, until when death comes to one of them he says: Now I repent; nor (for) those who die while they are disbelievers. For such We have prepared a painful chastisement.

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.
