Surah An-Nahl, ayah 119

ثُمَّ إِنَّ رَبَّكَ لِلَّذِينَ عَمِلُواْ ٱلسُّوٓءَ بِجَهَٰلَةٖ ثُمَّ تَابُواْ مِنۢ بَعۡدِ ذَٰلِكَ وَأَصۡلَحُوٓاْ إِنَّ رَبَّكَ مِنۢ بَعۡدِهَا لَغَفُورٞ رَّحِيمٌ ١١٩

Thumma inna rabbaka lilladhīna 'amilus-sū'a bijahālatin thumma tābū mim ba'di dhālika wa aslahū inna rabbaka mim ba'dihā laghafūrur rahīm

Then, indeed your Lord, to those who have done wrong out of ignorance and then repent after that and correct themselves - indeed, your Lord, thereafter, is Forgiving and Merciful.
