The Prophet ﷺ said, "It is not permissible for a woman who believes in Allah and the Last Day to travel for one day and night except with a Mahram."  

قَالَ النَّبِيُّ ﷺ لاَ يَحِلُّ لاِمْرَأَةٍ تُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ أَنْ تُسَافِرَ مَسِيرَةَ يَوْمٍ وَلَيْلَةٍ لَيْسَ مَعَهَا حُرْمَةٌ  

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  

That he heard the Prophet ﷺ saying, "It is not permissible for a man to be alone with a woman, and no lady should travel except with a Muhram (i.e. her husband or a person whom she cannot marry in any case for ever; e.g. her father, brother, etc.)." Then a man got up and said, "O Messenger of Allah ﷺ! I have enlisted in the army for such-and-such Ghazwa and my wife is proceeding for Hajj." Messenger of Allah ﷺ said, "Go, and perform the Hajj with your wife."  

أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ لاَ يَخْلُوَنَّ رَجُلٌ بِامْرَأَةٍ وَلاَ تُسَافِرَنَّ امْرَأَةٌ إِلاَّ وَمَعَهَا مَحْرَمٌ فَقَامَ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ اكْتُتِبْتُ فِي غَزْوَةِ كَذَا وَكَذَا وَخَرَجَتِ امْرَأَتِي حَاجَّةً قَالَ اذْهَبْ فَحُجَّ مَعَ امْرَأَتِكَ  

A man came to the Prophet ﷺ and said, "O Messenger of Allah ﷺ! I have enlisted in the army for such-andsuch Ghazwa, and my wife is leaving for Hajj." Messenger of Allah ﷺ said, "Go back and perform Hajj with your wife."  

جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي كُتِبْتُ فِي غَزْوَةِ كَذَا وَكَذَا وَامْرَأَتِي حَاجَّةٌ قَالَ ارْجِعْ فَحُجَّ مَعَ امْرَأَتِكَ  

The Prophet ﷺ said, "No man should stay with a lady in seclusion except in the presence of a Dhu- Muhram." A man stood up and said, "O Messenger of Allah ﷺ! My wife has gone out intending to perform the Hajj and I have been enrolled (in the army) for such-and-such campaign." The Prophet ﷺ said, "Return and perform the Hajj with your wife."  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَخْلُوَنَّ رَجُلٌ بِامْرَأَةٍ إِلاَّ مَعَ ذِي مَحْرَمٍ فَقَامَ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ امْرَأَتِي خَرَجَتْ حَاجَّةً وَاكْتُتِبْتُ فِي غَزْوَةِ كَذَا وَكَذَا قَالَ ارْجِعْ فَحُجَّ مَعَ امْرَأَتِكَ
