An-Nahl - ১৬:১১৯

ثُمَّ إِنَّ رَبَّكَ لِلَّذِينَ عَمِلُواْ السُّوءَ بِجَهَالَةٍ ثُمَّ تَابُواْ مِن بَعْدِ ذَلِكَ وَأَصْلَحُواْ إِنَّ رَبَّكَ مِن بَعْدِهَا لَغَفُورٌ رَّحِيمٌ
[16:119]
Yet surely your Lord, with respect to those who do an evil in ignorance, then turn after that and make amends, most surely your Lord after that is Forgiving, Merciful.
But verily thy Lord,- to those who do wrong in ignorance, but who thereafter repent and make amends,- thy Lord, after all this, is Oft-Forgiving, Most Merciful.
Then lo! thy Lord - for those who do evil in ignorance and afterward repent and amend - lo! (for them) thy Lord is afterward indeed Forgiving, Merciful.
