Is it permissible for a university student to pray in a shared prayer room for men and women—with a barrier preventing direct visibility—if there is a man present in the prayer room and no other place available to pray?

It is permissible to pray in the prayer room (musalla) when the time for prayer arrives, even if there is only one man present, and this is not considered an unlawful seclusion (khalwa muharramah); because the prayer room is a public place that anyone can enter at any moment.
