وَإِذَا جَآءَكَ ٱلَّذِينَ يُؤۡمِنُونَ بِـَٔايَٰتِنَا فَقُلۡ سَلَٰمٌ عَلَيۡكُمۡۖ كَتَبَ رَبُّكُمۡ عَلَىٰ نَفۡسِهِ ٱلرَّحۡمَةَ أَنَّهُۥ مَنۡ عَمِلَ مِنكُمۡ سُوٓءَۢا بِجَهَٰلَةٖ ثُمَّ تَابَ مِنۢ بَعۡدِهِۦ وَأَصۡلَحَ فَأَنَّهُۥ غَفُورٞ رَّحِيمٞ

When those come to thee who believe in Our signs, Say: "Peace be on you: Your Lord has inscribed for Himself (the rule of) mercy: verily, if any of you did evil in ignorance, and thereafter repented, and amend (his conduct), lo! He is Oft-forgiving, Most Merciful.
