Will a female teacher go to Hell if a student does not forgive her for what she did to him?

Denying rights is an ugly injustice, and its ugliness intensifies if it comes from an official. No specific oppressor is condemned to hellfire. The oppressed has three choices: pardoning to earn the reward of the patient, not pardoning, or seeking retribution in kind. Pardoning is the best and most rewarding option, as it is a transaction with Allah the Almighty, even if the oppressor does not deserve it.
