[Machine] I heard the Prophet ﷺ say, "A man should not be alone with a woman, and a woman should not travel unless she is accompanied by a mahram (a male relative whom she cannot marry)."
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ لَا يَخْلُوَنَّ رَجُلٌ بِامْرَأَةٍ وَلَا تُسَافِرِ امْرَأَةٌ إِلَّا وَمَعَهَا ذُو مَحْرَمٍ
