Surah Al-Ma'idah, ayah 34

إِلَّا ٱلَّذِينَ تَابُواْ مِن قَبۡلِ أَن تَقۡدِرُواْ عَلَيۡهِمۡۖ فَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ غَفُورٞ رَّحِيمٞ ٣٤

Illal-ladhīna tābū min qabli an taqdirū 'alayhim fa'lamū annallāha ghafūrur rahīm

Except for those who return [repenting] before you overcome [i.e., apprehend] them. And know that Allāh is Forgiving and Merciful.
