Most scholars are of the opinion that women cannot travel alone. They must be accompanied by a mahram (a relative with whom marriage is prohibited). Therefore, in journeys such as hajj they do not allow women to travel alone. The following Ahādīth are the basis of their view:
It is narrated by Abū Hurayrah:
لا يحل لامرأة تؤمن بالله واليوم الآخر تسافر مسيرة يوم وليلة إلا مع ذي محرم عليها )مسلم ، رقم (1339 :
"It is not permissible for a woman who believes in Allah and the Last Day to travel a distance for one day and one night without a mahram with her." (Muslim, No: 1339)
Abū Sa'īd narrates that the Prophet (sws) said:
نهى أن تسافر المرأة مسيرة يومين إلا ومعها زوجها أو ذو محرم (مسلم ، رقم: 827(
"A woman has been stopped from travelling a distance for two days except with her husband or mahram with her." (Muslim, No: 827)
