What is the husband's right to his working wife's salary, a large portion of which she gives to her family, and is he obligated to buy her a car for work, especially if he is asked to pay its full price?

A woman has the right to own and dispose of her property if she is of sound mind, and she is not obliged to give her husband anything from her salary. Rather, it is the husband's duty to provide for her. If the husband agrees to buy a car for the wife's work, he must fulfill that promise unless it causes him to be unable to fulfill his primary duties or leads him into something forbidden, provided that the woman's work is permissible and does not involve anything forbidden by Islamic law. The spouses should cooperate to strengthen their marital relationship, so the wife assisting her husband with her money or giving him the car are praiseworthy matters, even if they are not obligatory.
