الَّذينَ يَجتَنِبونَ كَبائِرَ الإِثمِ وَالفَواحِشَ إِلَّا اللَّمَمَ ۚ إِنَّ رَبَّكَ واسِعُ المَغفِرَةِ ۚ هُوَ أَعلَمُ بِكُم إِذ أَنشَأَكُم مِنَ الأَرضِ وَإِذ أَنتُم أَجِنَّةٌ في بُطونِ أُمَّهاتِكُم ۖ فَلا تُزَكّوا أَنفُسَكُم ۖ هُوَ أَعلَمُ بِمَنِ اتَّقىٰ

Those who avoid the major sins and immoralities, only [committing] slight ones. Indeed, your Lord is vast in forgiveness. He was most knowing of you when He produced you from the earth and when you were fetuses in the wombs of your mothers. So do not claim yourselves to be pure; He is most knowing of who fears Him.
