What should parents do when a disobedient daughter who commits grave sins returns home? Should they expel her or keep her, knowing that she poses a danger to her younger siblings?

The family of the girl must prevent her from evil deeds and change them with their own hands, because they have authority over her. The family must prevent their daughter from leaving the house, even by force, by confining her to her room, preventing her from communicating, and not expelling her from the home. For it is impermissible to forbid an evil with a greater evil, and it is impermissible for any of her family members to inflict a hadd punishment upon her or kill her. It is recommended to constantly advise and guide her, move away from environments that negatively affect her, prevent bad companions from visiting her, play beneficial materials for her while she is confined, ensure no disagreement among family members regarding her confinement, and sincerely supplicate for her.
