When does Hajj become Fardh on a woman?

Answer

Hajj becomes Fardh on her when: (1) She has sufficient funds for her own expenses and for the expenses of the accompanying mahram. (2) A pious mahram has to accompany her. If she is unable to find a pious mahram, then Hajj is not Fardh on her. It is not permissible for a woman to travel with even her own brother or father if they are faasiqs who have no care for the ahkaam of the Shariah.
