(74) باب سَفَرِ الْمَرْأَةِ مَعَ مَحْرَمٍ إِلَى حَجٍّ وَغَيْرِهِ
Qaza'ah reported:
I heard Abu Sa'id al-Khudri (Allah be pleased with him) saying: I heard four things from Allah's Messenger (ﷺ) which impressed me and captivated me (and one out of these is this), that he forbade a woman to undertake journey extending over two days but with her husband, or with a Mahram; and he then narrated the rest of the hadith.
