Is it permissible for a Muslim woman to send someone to perform Hajj or 'Umrah on her behalf if her father prevents her from going, and what should she do if she cannot find the means to afford it, and is it permissible for her to perform Hajj without his permission?

A woman is not obligated to perform Hajj unless she finds a mahram to travel with her, and she has sufficient funds for her Hajj and her mahram's expenses. If these are not available, then Hajj is not obligatory for her. It is not permissible for her to appoint someone to perform Hajj on her behalf; rather, she should wait until she is capable. A father is not allowed to prevent his daughter from performing the obligatory Hajj. If she is capable, Hajj becomes obligatory for her, even if her father does not give his permission.
