1. (Quran 5:39)
"But whoever repents after his wrongdoing and reforms, indeed, Allah will turn to him in forgiveness. Indeed, Allah is Forgiving and Merciful."
2. "The adulterer is not a believer while he is committing adultery, and the thief is not a believer while he is stealing, but there is a chance for repentance; (if he repents, Allah will accept the repentance)."
