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

When those who believe in Our revelations come to you, say, “Peace be upon you. Your Lord has mandated mercy on Himself. If anyone among you commits wrong out of ignorance, and then repents and reforms his ways, then He is Forgiving and Merciful.”
