A woman traveling without a mahram on the return journey

Question:
Honorable Shaykh, may Allah grant you success. He says: You have informed us, may Allah preserve you, that it is not permissible for a woman to travel without a mahram. He says: If I traveled with her, but when it was time for her to return, I was unable to travel with her and left her to return alone, knowing that the flight is about six hours, is that permissible?

Answer:
No, neither going nor returning. She must have a mahram with her both going and returning. The return and the going back are travel to which the hadith applies, whether going or returning. Rely on Allah, and you should take her back yourself; do not let one of her mahrams take her back. Yes.
