Is a wife who went to her family's home and did not return, without a divorce, considered disobedient (nashiz) or suspended (mu'allaqah), and what are the legitimate rights resulting from both cases?

A wife's staying in her parents' house without her husband's permission and her refusal to return to his home is considered nushooz (disobedience) and defiance of the husband's authority. The husband is advised to deal with the matter rationally, go to his wife, appease her, and bring her back home.
