وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ، أَخْبَرَنَا الضَّحَّاكُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ
" لاَ يَحِلُّ لاِمْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ تُسَافِرُ مَسِيرَةَ ثَلاَثِ لَيَالٍ إِلاَّ وَمَعَهَا ذُو مَحْرَمٍ " .
It is not lawful for a woman who believes in Allah and the Hereafter to travel for more than three nights journey except when there is a Mahram with her.
