Sayyiduna Abu Sa’id al-Khudri (Allah be pleased with him) narrates that the Messenger of Allah (Allah bless him & give him peace) said: “Let no woman travel for more than three days unless her husband or a Mahram is with her”. (Sahih Muslim).
Sayyiduna Abu Huraira (Allah be pleased with him) narrates that the Messenger of Allah (Allah bless him & give him peace) said: “It is unlawful for a woman who believes in Allah and the last day that she travels the distance of one day and one night without a Mahram accompanying her”. (Sahih al-Bukhari).
It is stated al-Fatwa al-Hindiyya:
“A Mahram is the husband and those for whom it is permanently unlawful to marry the woman, whether this is due to blood relationship, fosterage, or marriage (such as the father in-law, m). It is a condition that he is trusted, sane, and has reached puberty (baligh), whether he is free or a slave and regardless of whether he is a Muslim or a unbeliever. However, if he is a fire worshiper who considers marriage with relations and family members lawful, then she should avoid travelling with him. A boy who is close to puberty will be considered to be mature”.
