Is it permissible for an elderly woman who is past childbearing age to travel without a mahram?

Question:
He says: Honorable Shaykh, may Allah grant you success, is it permissible for a woman who is among the elderly women? Yes? Who is among the elderly women, advanced in age, is it permissible for her to travel alone without a mahram?

Answer:
No. The Messenger (peace and blessings be upon him) said: It is not permissible for a woman, whether she is old or young, who believes in Allah and the Last Day, to travel except with a mahram. Suppose she becomes ill on the road, or in the plane, or in the car; who will take care of her? Who will carry her? Who will look after her? She needs a mahram. Suppose the plane deviates from its route to another country; who will take care of her in the other country? Who will receive her? She must have a mahram with her. The elderly woman needs a mahram even more, to serve her, carry her, and attend to her. Yes.
