All hudud (the fixed Qur'anic punishments) are a right belonging to Allah, except for the hadd of qadhf (falsely accusing someone of zina), which is a right belonging to the one accused; if he forgives it, the punishment is dropped.

Question:
He says: Honorable Shaykh, may Allah grant you success

Answer:
Is the hadd of zina (unlawful sexual intercourse) purely a right belonging to Allah, or does the woman's awliya (close friends of Allah) have a right in it? All hudud are a right belonging to Allah, except for the hadd of qadhf. The hadd of qadhf is a right belonging to the one accused; if he forgives it, it is dropped. As for the remaining hudud, forgiveness does not apply to them. If they are established, they must be carried out, even if the woman's awliya or others forgive them. This is a right belonging to Allah. Yes.
