As for those who radically repent by turning entirely toward Divine Unity and who demonstrate this by following the holy way of life, Allah Most High will completely transform their negativity into goodness. He is ceaselessly forgiving, infinitely merciful.
إِلَّا مَنْ تَابَ وَآمَنَ وَعَمِلَ عَمَلًا صَالِحًا فَأُولَٰئِكَ يُبَدِّلُ اللَّهُ سَيِّئَاتِهِمْ حَسَنَاتٍ ۗ وَكَانَ اللَّهُ غَفُورًا رَحِيمًا
Illaa man taaba wa 'aamana wa 'amila 'amalan saalihan fa ulaaa'ika yubad dilul laahu saiyi aatihim hasanaat; wa kaanal laahu Ghafoorar Raheemaa
