6 : 54
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
And when those come to you who believe in Our verses, say, "Peace be upon you. Your Lord has decreed upon Himself mercy: that any of you who does wrong out of ignorance and then repents after that and corrects himself - indeed, He is Forgiving and Merciful."
