What is the ruling in religion and law concerning a wife's refusal to visit her husband's family, and her leaving her family's home without her husband's knowledge, despite his prohibition and threat of divorce?

No home is free from marital disputes, and both spouses should address them with wisdom and gentleness. As for conditional divorce, it occurs upon the fulfillment of the condition. So, if the wife leaves without her husband's permission, she is divorced from him by triple talaq, according to the soundest opinions. Therefore, she must be cautious about leaving without his permission, and the husband is advised to grant her permission to avoid the occurrence of divorce. Furthermore, the wife must fear Allah regarding her husband and obey him in permitting the children to maintain ties with their kin. Honoring the husband's family is part of honoring the husband himself.
