Is there any hope for a girl who committed multiple indecencies and then completely repented from them?

If repentance is sincere and fulfills its conditions, then sins are erased, and the repentant person returns as if they had never sinned. The Almighty said: "Say, 'O My servants who have transgressed against themselves [by committing sins], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, He is the Forgiving, the Merciful.'" Cursing the religion is apostasy, and repentance for it involves uttering the Two Testimonies of Faith and performing ghusl (ritual bath). The rights of people require restitution or seeking their forgiveness. For other sins, it is sufficient to cease committing them, feel remorse, and resolve not to return to them. One must strive in acts of obedience, supererogatory prayers, and ذكر (remembrance of Allah).
