The ruling on a woman traveling by plane without a mahram

Question:
Khalid from Riyadh, please, Khalid. Peace be upon you, and Allah's mercy and blessings. And upon you peace. And upon you peace. May Allah forgive you, O Shaykh. My father has a wife, and he asks me to book for her and handle the booking procedures via air travel and arrange it, and that she go alone. She has three children from him, and they are young. I said, "O my father, it is necessary to take, meaning, a mahram with her." He said, "The trip is domestic and close." Is it permissible for me to obey him in this matter, or what?

Answer:
Do not obey him in this matter; the mahram is necessary. The Prophet (peace and blessings be upon him) said: The hadith is general, whether she travels by plane, by car, by ship, on camels, or on foot; the mahram is necessary due to the command of the Messenger (peace and blessings be upon him). His saying "it is not permissible" means it is forbidden. A man came to the Prophet (peace and blessings be upon him) wanting to write his name for the expedition, and he informed the Messenger (peace and blessings be upon him) that his wife had gone out for Hajj. So he (peace and blessings be upon him) said to him, "Go back and perform Hajj with your wife." He sent him back from the expedition to perform Hajj with his wife. So the mahram is very important with a woman when she travels. Yes.
