Surat Aal-i-Imraan (The Family of Imraan) - آل عمران

وَٱلَّذِينَ إِذَا فَعَلُوا۟ فَٰحِشَةً أَوْ ظَلَمُوٓا۟ أَنفُسَهُمْ ذَكَرُوا۟ ٱللَّهَ فَٱسْتَغْفَرُوا۟ لِذُنُوبِهِمْ وَمَن يَغْفِرُ ٱلذُّنُوبَ إِلَّا ٱللَّهُ وَلَمْ يُصِرُّوا۟ عَلَىٰ مَا فَعَلُوا۟ وَهُمْ يَعْلَمُونَ ﴿١٣٥﴾

And those who when they commit an indecency or do injustice to their souls remember Allah and ask forgiveness for their faults-- and who forgives the faults but Allah, and (who) do not knowingly persist in what they have done.
