Surah Al-A'raf, ayah 153

وَٱلَّذِينَ عَمِلُواْ ٱلسَّيِّـَٔاتِ ثُمَّ تَابُواْ مِنۢ بَعۡدِهَا وَءَامَنُوٓاْ إِنَّ رَبَّكَ مِنۢ بَعۡدِهَا لَغَفُورٞ رَّحِيمٞ ١٥٣

Walladhīna 'amilus-sayyi'āti thumma tābū mim ba'dihā wa āmanū inna rabbaka mim ba'dihā laghafūrur rahīm

But those who committed misdeeds and then repented after them and believed - indeed your Lord, thereafter, is Forgiving and Merciful.
