Is the wife entitled to leave her family's home for work or to visit her grandmother, after her husband expelled her and threatened to end the relationship, given that she was subjected to violence and humiliation from him and his mother?

If the husband's actions are correct, then he is abusive and violates the Islamic etiquette of good companionship, for a believer is neither a slanderer nor a curser. Beating one's wife without a legitimate religious reason is oppression and aggression, especially if she is pregnant. The husband's hasty decision to divorce is a mistake, and his statement: "If you do not come to me, our companionship is over" is considered a conditional divorce in an allusive form, which takes effect if he intended divorce by it. The wife has the right to refuse to return to his house if she fears harm from him. It is advisable to seek reconciliation and the intervention of wise people. If the husband's mother unjustly insults the wife, she has done wrong, and she should have sought reconciliation. There is no blame upon the wife for going out with her husband's permission for work, recreation, or visitation. The wife has an independent financial standing, and she has the right to dispose of her money within permissible limits, and preventing her from helping her family with her money is wrong.
