It is not permissible for a woman to travel without a mahram, even if she is travelling for the obligatory Hajj or obligatory ‘Umrah, according to the more correct of the two scholarly opinions, because of the report narrated by al-Bukhaari (1729) and Muslim (2391) from Ibn ‘Abbaas (may Allaah be pleased with him) who said: The Prophet (peace and blessings of Allaah be upon him) said: “No woman should travel except with a mahram, and no man should enter upon her unless there is a mahram with her.” A man said: O Messenger of Allaah, I want to go out on such and such a campaign, and my wife wants to go for Hajj.” He said: “Do Hajj with her.”
Because of this hadeeth and others which indicate that it is haraam for a woman to travel without a mahram, a number of scholars are of the view that the presence of a mahram is one of the conditions of Hajj being obligatory for a woman. So if you cannot find a mahram to travel with you, Hajj is not obligatory for you, and you are excused, but will be rewarded for your intention in sha Allaah.
Imam Ahmad (may Allaah have mercy on him) was asked about a woman who was well off but did not have a mahram – is Hajj obligatory for her? He said: No.
The Standing Committee was also asked (11/95): I have a problem for which I want to find a solution from Allaah, who is Merciful towards His slaves. It has to do with my performing the obligation of Hajj. I am a woman in my fifties and for two years I have wanted to travel to perform the obligatory Hajj. What is preventing me from travelling is that I do not have a mahram who can travel with me. My husband has no concerns except work and worldly matters, and he does not intend to travel for Hajj, unless it is arranged for free by the company for which he works. That will not happen until his turn comes, and I am afraid that I may die before I perform this duty. I have enough money to pay for provisions and the journey. To sum up: all my mahrams are unable to travel with me because of their work.
If the situation is as described, and neither your husband nor any of your mahrams is able to travel with you so that you can perform the obligatory Hajj, then you are not obliged to do it so long as this situation persists, because the presence of your husband or mahram for the journey to Hajj is one of the conditions of it being obligatory for you. It is haraam for you to travel for Hajj or any other purpose without a mahram, even with your brother’s wife and a group of women, according to the more correct of the two scholarly views, because the Prophet (peace and blessings of Allaah be upon him) said: “No woman should travel except with a mahram.” Saheeh – agreed upon. Strive to do righteous deeds which do not require you to travel, and be patient, in the hope that Allaah will make things easy for you and grant you the means of travelling with your husband or a mahram.
