It is not permissible for a woman to travel without a mahram

Question:
May Allah reward you with good, and may He reward you as well. From the Holy City of Makkah, a message signed by one of our sisters from there, saying: Dal, Shin, Sad. She asks: Honorable Shaykh, Shaykh Salih, she says: Is it permissible for a woman to travel alone if the distance between her town and the other town is about two or three hours? May Allah reward you with good.

Answer:
It is not permissible for a woman to travel without a mahram if the distance between the two towns or elsewhere is eighty kilometers or more; the mahram is required. The Messenger (peace and blessings be upon him) said: “It is not permissible for a woman who believes in Allah and the Last Day to travel unless she has with her a mahram,” and the two days referred to means for a mount, the walking distance at that time, which has been estimated at eighty kilometers in this time, whether she covers it in one hour, less, or more. Yes.
