The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)
حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ عُبَيْدِ اللَّهِ، قَالَ حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ تُسَافِرُ الْمَرْأَةُ ثَلاَثًا إِلاَّ وَمَعَهَا ذُو مَحْرَمٍ " .
Ibn `Umr reported the Prophet (SWAS) as saying :A woman must not make a journey of three days unless she is accompanied by a man who is within the prohibited degree
