 53:32

الَّذِينَ يَجْتَنِبُونَ كَبَائِرَ الْإِثْمِ وَالْفَوَاحِشَ إِلَّا اللَّمَمَ ۚ إِنَّ رَبَّكَ وَاسِعُ الْمَغْفِرَةِ ۚ هُوَ أَعْلَمُ بِكُمْ إِذْ أَنْشَأَكُمْ مِنَ الْأَرْضِ وَإِذْ أَنْتُمْ أَجِنَّةٌ فِي بُطُونِ أُمَّهَاتِكُمْ ۖ فَلَا تُزَكُّوا أَنْفُسَكُمْ ۖ هُوَ أَعْلَمُ بِمَنِ اتَّقَىٰ ﴿٣٢﴾

32. Those who avoid major sins and indecencies—except what is slight—your Lord is of Vast Forgiveness. He knew you well, ever since He produced you from the earth, and ever since you were embryos in your mothers’ wombs. So do not acclaim your own virtue; He is fully aware of the righteous.
