What is the ruling on a woman who is revocably divorced leaving her marital home without her husband's permission to visit her brothers, given that the husband was the one who made her leave the house?

A woman who has been given a revocable divorce (talaq raj'i) must remain in the marital home. It is impermissible for her to leave it except out of necessity, and her husband is not allowed to expel her. If he expels her, the husband incurs sin. It is not permissible for a woman observing her 'iddah (waiting period) to go out to visit her siblings unless she feels lonely and goes out for companionship during the day, in which case there is no harm in that. It is advised to be cautious about divorce and to strive for reconciliation and reunification, especially when there are children involved.
