Is it permissible to give money to one's mother for her unveiled daughter to study at a mixed-gender university?

It is not permissible to assist the mother, financially or otherwise, in sending her daughter out unveiled to study at a mixed-gender university. Rather, it is obligatory to prevent her from this evil, and to denounce it to the daughter and the mother according to one's ability, clarifying the impermissibility of a woman going out unveiled and the harms of studying in mixed-gender universities. Nevertheless, one must still treat the mother with kindness and dutifulness.
