The Prophet ﷺ said, "A woman should not travel except with a Dhu-Mahram (her husband or a man with whom that woman cannot marry at all according to the Islamic Jurisprudence), and no man may visit her except in the presence of a Dhu-Mahram." A man got up and said, "O Messenger of Allah ﷺ! I intend to go to such and such an army and my wife wants to perform Hajj." The Prophet ﷺ said (to him), "Go along with her (to Hajj).  

قَالَ النَّبِيُّ ﷺ لاَ تُسَافِرِ الْمَرْأَةُ إِلاَّ مَعَ ذِي مَحْرَمٍ وَلاَ يَدْخُلُ عَلَيْهَا رَجُلٌ إِلاَّ وَمَعَهَا مَحْرَمٌ فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ إِنِّي أُرِيدُ أَنْ أَخْرُجَ فِي جَيْشِ كَذَا وَكَذَا وَامْرَأَتِي تُرِيدُ الْحَجَّ فَقَالَ اخْرُجْ مَعَهَا  

[Machine] The Prophet ﷺ heard saying, "A man should not be alone with a woman, nor should a woman travel unless she is accompanied by a mahram."  

سَمِعَ النَّبِيَّ ﷺ يَقُولُ «لَا يَخْلُوَنَّ رَجُلٌ بِامْرَأَةٍ وَلَا تُسَافِرُ إِلَّا وَمَعَهَا ذُو مَحْرَمٍ»  

[Machine] I heard the Messenger of Allah ﷺ while he was on the pulpit giving a sermon saying, "A woman should not travel except with a mahram (a male relative whom she cannot marry), and no man should be alone with a woman except in the presence of a mahram."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ وَهُوَ عَلَى الْمِنْبَرِ يَخْطُبُ «لَا تُسَافِرَنَّ امْرَأَةٌ إِلَّا بِذِي مَحْرَمٍ وَلَا يَخْلُوَنَّ رَجُلٌ بِامْرَأَةٍ إِلَّا بِذِي مَحْرَمٍ»  

The Prophet ﷺ said, "A woman should not travel except with a Dhu-Mahram (her husband or a man with whom that woman cannot marry at all according to the Islamic Jurisprudence), and no man may visit her except in the presence of a Dhu-Mahram." A man got up and said, "O Messenger of Allah ﷺ! I intend to go to such and such an army and my wife wants to perform Hajj." The Prophet ﷺ said (to him), "Go along with her (to Hajj). (Using translation from Bukhārī 1862)  

قَالَ رَسُولُ اللهِ ﷺ «لَا تُسَافِرُ الْمَرْأَةُ إِلَّا مَعَ ذِي مَحْرَمٍ وَلَا يَدْخُلُ عَلَيْهَا رَجُلٌ إِلَّا وَمَعَهَا مَحْرَمٌ» فَقَالَ رَجُلٌ يَا رَسُولَ اللهِ إِنِّي أُرِيدُ أَنْ أَخْرُجَ فِي جَيْشِ كَذَا وَكَذَا وَامْرَأَتِي تُرِيدُ الْحَجَّ قَالَ «اخْرُجْ مَعَهَا»  

"لا تُسَافِرِ المَرْأةُ إِلا مَعَ ذِي مَحْرَمٍ، وَلَا يَدْخُلُ عَلَيهَا رَجُلٌ إِلا وَمَعَهَا ذُو مَحْرَمٍ".  

"لا يَدْخُلُ رَجُلٌ عَلَى امْرَأَةٍ، وَلا يُسَافِرُ مَعَهَا إِلا مَعَهَا ذُو مَحْرَمٍ".
