What is the punishment for parents who separate a husband and wife and order the husband to divorce his righteous wife without cause, and what is the punishment for the oppressor in this situation?

Separating spouses is among the gravest of sins, for "he who incites a woman against her husband or a servant against his master is not one of us." It is among the greatest deeds of Iblis, by which he draws his legions closer. Therefore, the one who commits such an act must repent to Allah, strive to mend what he has corrupted, and seek forgiveness from those he has wronged.
