It was narrated from Abu Hurairah that the Prophet said: “It is not permissible for a woman who believes in Allah and the Last Day to travel for more than one day’s distance without a Mahram.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا شَبَابَةُ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَالَ " لاَ يَحِلُّ لاِمْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ أَنْ تُسَافِرَ مَسِيرَةَ يَوْمٍ وَاحِدٍ لَيْسَ لَهَا ذُو حُرْمَةٍ " .
