Is a wife entitled to disobey her husband's command by refusing to spend from her salary on her family, given that he does not provide her monthly maintenance and she contributes with him to paying the housing rent and other expenses?

A woman has an independent financial standing, and she has the right to dispose of her lawful wealth without her husband's permission. He does not have the right to prevent her from giving her family from her salary. She is not obliged to obey him if he prevents her, but she should do so secretly to avoid conflict. The wife's maintenance is obligatory upon her husband, even if she is wealthy. It is a noble act from the wife to help her husband with household expenses, and the husband should appreciate this kindness from his wife and not prevent her from being charitable to her family with her own money.
