Don't insult ALLAH by saying that he won't FORGIVE me...
Becouse ALLAH says....
[Surah az-zumar: 53]
Say, "O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah . Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful."
What ever YOU have DONE...
Just ASK FOR ALLAH'S FORGIVENESS
