وَإِذا جاءَكَ الَّذينَ يُؤمِنونَ بِآياتِنا فَقُل سَلامٌ عَلَيكُم ۖ كَتَبَ رَبُّكُم عَلىٰ نَفسِهِ الرَّحمَةَ ۖ أَنَّهُ مَن عَمِلَ مِنكُم سوءًا بِجَهالَةٍ ثُمَّ تابَ مِن بَعدِهِ وَأَصلَحَ فَأَنَّهُ غَفورٌ رَحيمٌ

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."
