Verse 54

وَإِذَا جَآءَكَ ٱلَّذِينَ يُؤْمِنُونَ بِـَٔايَـٰتِنَا فَقُلْ سَلَـٰمٌ عَلَيْكُمْ كَتَبَ رَبُّكُمْ عَلَىٰ نَفْسِهِ ٱلرَّحْمَةَ أَنَّهُۥ مَنْ عَمِلَ مِنكُمْ سُوٓءًۢا بِجَهَـٰلَةٍ ثُمَّ تَابَ مِنۢ بَعْدِهِۦ وَأَصْلَحَ فَأَنَّهُۥ غَفُورٌ رَّحِيمٌ

And when those who believe in Our signs come to you, you shall tell them peace be upon you. Your Lord has decreed mercy onto Himself. Indeed whoever from among you that does an evil deed out of ignorance, then repents afterwards and becomes righteous then He is indeed All Forgiving, All Merciful.
