Salaam. Do Muslim women need a mahram to go on a journey?
Alaikumassalam wa rahmatullah,
There is a strong hadith that comes from multiple Companions that says a woman shouldn’t go on a journey that takes a day and night (24 hours) unless there is a mahram with her. It is allowed (by Ibn Jibrin) for a mahram to drop off a woman at an airport and let her travel alone to the destination where another mahram picks her up. The scholar al-Baji says the restriction only applies to young women, elders may travel alone (although other scholars disagree). I haven’t studied the hadiths on this matter in detail, so I don’t have a personal opinion on it.
