What is the Sharia ruling regarding a wife who demands divorce, abuses her husband and his family, and refuses to return to her home unless her husband brings her back, while he refuses to do so because he feels he has not wronged her?

Marriage was legislated for great purposes, the most important of which is the stability of marital life to be a suitable environment for the upbringing of children. This is achieved through good companionship, respect, and understanding between the spouses. You have done well by being patient with your wife and her wrongdoing by requesting a divorce, which is forbidden by Islamic law unless there is a valid justification. We recommend appointing wise people from the family to reconcile between you in case of discord, as there is great good in it, especially with the presence of children, to avoid their harm from divorce. And your taking her to her home is commendable to appease her and encourage reconciliation. If reconciliation is achieved, that is what is desired; otherwise, consider the matter of divorce if it is the more appropriate solution.
