What is the ruling regarding a wife remaining in her family's home for two and a half months without her husband's permission, while she is seven months pregnant, and refuses to return to the marital home unless her husband goes to bring her back, and is a "house of obedience" considered a suitable solution in this situation?

A wife's obedience to her husband in what is right takes precedence over her obedience to her parents, and her husband has more authority over her than they do. The obligatory maintenance due from the husband is what suffices for a reasonable standard of living, according to the couple's circumstances. A wife leaving her home without her husband's permission, except for a necessity, constitutes disobedience (nushooz). Child custody after divorce belongs to the mother unless there is a legitimate Islamic impediment. Divorce should not be resorted to except when reconciliation becomes impossible.
