حَتَّىٰٓ إِذَا جَآءَ أَحَدَهُمُ ٱلْمَوْتُ قَالَ رَبِّ ٱرْجِعُونِ
[For such is the state of the disbelievers], until, when death comes to one of them, he says, "My Lord, send me back
لَعَلِّىٓ أَعْمَلُ صَـٰلِحًا فِيمَا تَرَكْتُ ۚ كَلَّآ ۚ إِنَّهَا كَلِمَةٌ هُوَ قَآئِلُهَا ۖ وَمِن وَرَآئِهِم بَرْزَخٌ إِلَىٰ يَوْمِ يُبْعَثُونَ
That I might do righteousness in that which I left behind." No! It is only a word he is saying; and behind them is a barrier until the Day they are resurrected.
فَمَن ثَقُلَتْ مَوَٰزِينُهُۥ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ
And those whose scales are heavy [with good deeds] - it is they who are the successful.
وَمَنْ خَفَّتْ مَوَٰزِينُهُۥ فَأُو۟لَـٰٓئِكَ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُمْ فِى جَهَنَّمَ خَـٰلِدُونَ
But those whose scales are light - those are the ones who have lost their souls, [being] in Hell, abiding eternally.
