The ruling on a wife leaving her husband's house without his permission

Question:
May Allah reward you, Your Eminence, father. The questioner says: This woman is constantly in conflict with her husband. Then her husband married another woman, so the first wife left her husband's house without his permission. Is her action valid? And what is the expiation for that if her action was wrong?

Answer:
This is a judicial matter, a dispute between two spouses, a judicial matter that is referred to the courts. But if her husband left his house for a reason, and he was negligent in his rights toward her, then she is excused. But if he was not negligent in his rights toward her, then her leaving is a sin and it is not permissible for her to do so. The mere fact that he has a second wife is not an excuse for a Muslim. It is his right to marry four women, as long as he is just. This is his right, and she has no claim against him. Yes.
