Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "It is not lawful for a woman who believes in Allah and the Last Day to travel for three days or more without a mahram, that is, without her father, son, brother, husband, or any other mahram relative." This narration is from Abu Mu'awiyah. In the narration of the other two narrators, the words are that no woman should travel for a day or more. In the narration of Ibn Abi Zaidah, three days are mentioned.
