Is it permissible for the mother to take her husband's money and give it to their daughters and their children without his knowledge, and is the children's silence about this considered part of parental approval?

A husband must provide for his wife and children equitably. If he falls short in this, it is permissible for the wife to take from his money, without his knowledge, what suffices her and her child. However, if the husband is fulfilling his duty, it is not permissible for the wife to take from his money except with his permission, due to the sanctity of a Muslim's wealth. If the mother takes money unjustly, the son must advise her kindly, and if she does not respond, there is no blame on him for informing his father. If the wife works for wages and her husband withholds her right, she may take her right without his knowledge.
