Is boycotting a father who interferes in his daughter’s marital life, abuses her husband, and refuses to see her after she tried to reconcile between them, considered disobedience to parents, and is she excused for that?

Parents should support their daughter's marital life in a way that strengthens it, and they can intervene with advice or to reconcile if there is injustice or negligence. If the father insists on disruptive interference, he must not be obeyed in that, and the daughter is not considered disobedient; rather, she will be rewarded for her patience. It is advisable to involve wise people to reconcile between the father and his daughter, and the daughter should continue to honor her father and avoid angering him, while seeking help through prayer and improving her relationship with Allah.
