Ruling on a father taking from his daughter's mahr without her consent?

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: In our tribe, the woman is not consulted regarding the mahr; rather, her father is the one who determines it, and he is the one who consumes it, giving her from it only a trivial amount. Is it permissible for the woman's father to do that?

Answer:
[He may take from his daughter's mahr] what does not harm her and what she does not need, but if it harms her, it is not permissible for him to do so. In fact, he has the right to take from the wealth of his child and his son, based on the saying of the Messenger (peace and blessings be upon him): "You and your wealth belong to your father." He has the right to take from his son's wealth as long as it does not reach the level of harming the son, or as long as he does not take something the son needs. So the father takes, he takes from his daughter's mahr and from his son's wealth, especially this is specific to the father.
