7:8
وَالْوَزْنُ يَوْمَئِذٍ الْحَقُّ فَمَن ثَقُلَتْ مَوَازِينُهُ فَأُوْلَـئِكَ هُمُ الْمُفْلِحُونَ
The balance that day will be true (to nicety): those whose scale (of good) will be heavy, will prosper:
7:9
وَمَنْ خَفَّتْ مَوَازِينُهُ فَأُوْلَـئِكَ الَّذِينَ خَسِرُواْ أَنفُسَهُم بِمَا كَانُواْ بِآيَاتِنَا يِظْلِمُونَ
Those whose scale will be light, will be their souls in perdition, for that they wrongfully treated Our signs.
23:102
فَمَن ثَقُلَتْ مَوَازِينُهُ فَأُوْلَئِكَ هُمُ الْمُفْلِحُونَ
Then those whose balance (of good deeds) is heavy,- they will attain salvation:
23:103
وَمَنْ خَفَّتْ مَوَازِينُهُ فَأُوْلَئِكَ الَّذِينَ خَسِرُوا أَنفُسَهُمْ فِي جَهَنَّمَ خَالِدُونَ
But those whose balance is light, will be those who have lost their souls, in Hell will they abide.
