Is it permissible for daughters to supplicate against their father, who doubts and slanders their and their sisters’ honor, and what is their duty towards him?

Praise be to Allah. An father who accuses his daughters of immorality without proof is a transgressor and has committed a major sin. However, this does not nullify his rights over them. It is not permissible for them to raise their voices at him, or harm him, or supplicate against him, even if he is unjust. Rather, they must associate with him in a good manner and advise him gently and courteously. They may also supplicate for his guidance and ask Allah to protect them from his evil.
