(74) باب سَفَرِ الْمَرْأَةِ مَعَ مَحْرَمٍ إِلَى حَجٍّ وَغَيْرِهِ
Abu Sa'id al-Khudri (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:
It is not lawful for a woman believing in Allah and the Hereafter to undertake journey extending over three days or more, except when she is in the company of her father, or her son, or her husband, or her brother, or any other Mahram.
