Is the money that the university returned to the female student due to her excellence, and for which the student is obligated to work for the university or the government, her right or her father's right, knowing that the father is not in need of the money, and the student wishes to use it to complete her postgraduate studies?

The grant is the right of the questioner. What the father paid is a donation and cannot be retracted. It is permissible for the father to take from his son's money what he needs, without harming the son or giving it to another child, provided that he does not act unjustly towards him and does not take anything to which the son's need is attached. According to the majority of jurists, the father is not allowed to take except if he is in need. If he is not in need, then he is not allowed to take except with the son's consent.
