Ruling on a woman traveling with her daughter's husband for Hajj and 'Umrah

Is it permissible for a woman to go with her daughter's husband for Hajj or 'Umrah, or to visit the Noble Prophet's Mosque?
Answer: The daughter's husband is a mahram (a relative one may not marry); her daughter's husband is a mahram for her. So if she travels with him for Hajj or 'Umrah, or for any permissible travel, there is nothing wrong with it; because he is a mahram. Her daughter's husband, her mother's husband, and her grandmother's husband, all of them are mahrams, as well as her son's daughter's husband, and her daughter's daughter's husband. Yes.
