What is the legitimate Islamic ruling regarding what a wife is entitled to demand from her husband, given that she bears the larger share of household and children's expenses, feels psychological and physical pressure, and the husband refuses to acknowledge his full Islamic responsibility for providing financial support?

The husband must provide for his wife and children according to what is customary. The wife is not obligated to spend on herself or her home, even if she is wealthy, unless she voluntarily chooses to do so. Whatever the wife earns from her work is her exclusive right. However, if the husband stipulates a portion of her salary in exchange for his permission for her to work, the fatwa (religious legal opinion) confirms the validity of this condition, and she is obligated to fulfill it. The wife's maintenance takes precedence over the maintenance of relatives when there is a conflict. It is the amount sufficient for food, housing, and clothing, according to the circumstances of both spouses. The wife has the right to demand maintenance from her husband, and if he does not provide for her according to what is customary, or if he is in financial difficulty, she may refer the matter to the judiciary to compel him to provide maintenance or to separate them if she so desires.
