The Prophet ﷺ said, "A woman should not travel for more than three days except with a Dhi-Mahram (i.e. a male with whom she cannot marry at all, e.g. her brother, father, grandfather, etc.) or her own husband.)"
قُلْتُ لأَبِي أُسَامَةَ حَدَّثَكُمْ عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ ؓ أَنَّ النَّبِيَّ ﷺ قَالَ لاَ تُسَافِرِ الْمَرْأَةُ ثَلاَثَةَ أَيَّامٍ إِلاَّ مَعَ ذِي مَحْرَمٍ
During some of the Ghazawat of Messenger of Allah ﷺ a woman was found killed, so Messenger of Allah ﷺ forbade the killing of women and children.
قُلْتُ لأَبِي أُسَامَةَ حَدَّثَكُمْ عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ ؓ قَالَ وُجِدَتِ امْرَأَةٌ مَقْتُولَةً فِي بَعْضِ مَغَازِي رَسُولِ اللَّهِ ﷺ فَنَهَى رَسُولُ اللَّهِ ﷺ عَنْ قَتْلِ النِّسَاءِ وَالصِّبْيَانِ
It is not lawful for a woman who believes in Allah and the Hereafter to undertake a day's journey except in the company of a Mahram. (Using translation from Muslim 1339b)
عَنِ النَّبِيِّ ﷺ قَالَ لَا يَحِلُّ لِامْرَأَةٍ تُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ تُسَافِرُ يَوْمًا إِلَّا مَعَ ذِي مَحْرَمٍ
“A woman is not to travel the distance of a day and a night unless she is accompanied by someone who is a Mahram.” (Using translation from Tirmidhī 1170)
قَالَ رَسُولُ اللهِ ﷺ لَا تُسَافِرْ امْرَأَةٌ مَسِيرَةَ يَوْمٍ تَامٍّ إِلَّا مَعَ ذِي مَحْرَمٍ
[Machine] The Messenger of Allah ﷺ said, "A woman should not travel for a distance of three days except in the company of a relative."
قَالَ رَسُولُ اللهِ ﷺ لَا تُسَافِرْ امْرَأَةٌ ثَلَاثًا إِلَّا مَعَ ذِي رَحِمٍ
A woman must not make a journey of three days unless she is accompanied by a man who is within the prohibited degree. (Using translation from Abū Dāʾūd 1727)
عَنِ النَّبِيِّ ﷺ قَالَ لَا تُسَافِرِ امْرَأَةٌ مَسِيرَةَ ثَلَاثَةِ أَيَّامٍ إِلَّا مَعَ ذِي مَحْرَمٍ
