Salam aleykom,  Are women allowed to go to hajj without a mahram? For instance with a group? Do the Saudis allow that? I know women who went with groups and had "fake" mahrams who got into trouble becausr of that during their hajj trip.  I also heard that the Saudis require women to be a certain age in order to do hajj without a mahram with them. Is that true and what is the required age in that case?
