Qur'an 53:32

ٱلَّذِينَ يَجْتَنِبُونَ كَبَـٰٓئِرَ ٱلْإِثْمِ وَٱلْفَوَٰحِشَ إِلَّا ٱللَّمَمَ ۚ إِنَّ رَبَّكَ وَٰسِعُ ٱلْمَغْفِرَةِ ۚ هُوَ أَعْلَمُ بِكُمْ إِذْ أَنشَأَكُم مِّنَ ٱلْأَرْضِ وَإِذْ أَنتُمْ أَجِنَّةٌ فِى بُطُونِ أُمَّهَـٰتِكُمْ ۖ فَلَا تُزَكُّوٓا۟ أَنفُسَكُمْ ۖ هُوَ أَعْلَمُ بِمَنِ ٱتَّقَىٰٓ

Those who avoid enormities of sin and abominations, save the unwilled offences - (for them) lo! thy Lord is of vast mercy. He is Best Aware of you (from the time) when He created you from the earth, and when ye were hidden in the bellies of your mothers. Therefor ascribe not purity unto yourselves. He is Best Aware of him who wardeth off (evil).
