What is the religious ruling on a husband who swore to his wife by that which is unlawful, and refused to consult religious scholars to rule on his oath, and compelled her not to approach him, or wear house clothes in front of him, or sleep with him in the same room? And what is incumbent upon the wife to do regarding this?

The fundamental principle is the wife's obligation to obey her husband, and her leaving the home is not permissible without his permission, except in cases of necessity, such as seeking help from someone who can avert harm from her. If her departure is for such a reason, it is permissible for her; otherwise, it is not. What the husband said about forbidding his wife varies depending on his intention. It could be a divorce (talaq), or a revocable divorce (zihar), or an oath (yamin), and each has its own ruling and implications. She must explain the ruling to him so that he can clarify his intention. If he intended zihar, he is forbidden from intimate relations with her before performing expiation. If he intended divorce, it is a revocable divorce. If he intended an oath or did not intend anything specific, it is an oath requiring expiation upon breaking it. Mediation can be used to reconcile between them.
