Is it permissible for the husband to donate or delay his wife's monthly allowance, which she needs for her personal expenses and those of their children, under the pretext of giving it as charity? What is the ruling on this, and is the wife sinful for being angry at this behavior?

If the husband falls short in providing the basic necessities for the marital home (such as beds, a refrigerator, and a cooking appliance), this falls under the obligatory maintenance due from him, and he is not permitted to be remiss in it. However, if the husband fulfills his obligatory maintenance towards his wife and children, he is permitted to give charity from his surplus wealth, and the wife has no right to object. Rather, it is recommended that she encourage him to do so, because giving charity from wealth that is surplus to one's needs and the sufficiency of those he supports is commendable.
