What is the ruling on parents insisting that their daughter remove her hijab in order to complete her university studies, while she refuses to do so, preferring to quit her studies over removing her hijab, and there is no possibility of providing safe alternative accommodation?

It is not permissible for a girl to remove her hijab in obedience to her parents or to complete her studies, except in a case of necessity where she cannot study while wearing the hijab. This necessity could be if the studies are essential for her or for the Muslim community, and they cannot be completed except by removing the hijab. However, if she can study while wearing the hijab, even if it means renting a secure accommodation, then she must complete her studies with the hijab. If removing it becomes necessary, it is only permissible out of dire necessity.
