quran:27:11 –

Otherwise, he who wrongs, then substitutes good after evil - indeed, I am Forgiving and Merciful.  

except him who has wronged, his soul, but then changed ˹his wrong˺ for good — he ˹then˺ performs ˹good deeds˺ — after ˹having done˺ evil, in other words, ˹he has˺ repented, then truly I am Forgiving, Merciful, I will accept his repentance and forgive him.
القرآن:٢٧:١١ –

إِلَّا مَنْ ظَلَمَ ثُمَّ بَدَّلَ حُسْنًا بَعْدَ سُوءٍ فَإِنِّي غَفُورٌ رَحِيمٌ  

{إلا} لكن {من ظلم} نفسه {ثم بدَّل حُسناً} أتاه {بعد سوءٍ} أي تاب {فإني غفور رحيم} أقبل التوبة وأغفر له.
