Will Allah forgive a girl who sinned after repenting, and is the injustice she faces from the General Manager a trial?

Adultery is one of the gravest sins and major enormities. Allah Almighty has linked its mention with polytheism and unlawful killing. Whoever commits such acts will have their torment doubled on the Day of Resurrection and will abide therein disgraced, except for those who repent, believe, and do righteous deeds, for Allah will change their evil deeds into good ones. Repentance must be sincere, and one must regret what has passed, for Allah accepts repentance and forgives all sins. To be safeguarded from falling into what is forbidden, one must block the devil's pathways and avoid seclusion with non-mahram individuals, for "No man is alone with a woman but the devil is the third of them." The injustice you experienced might be due to a sin, for a believer is punished with affliction for some of their sins.
