According to Ibn `Umar

According to Ibn `Umar, may Allah be pleased with him and his father, the Messenger of Allaah (peace and blessings of Allaah be upon him) said:

 The woman must not travel three days' walk unlessaccompanied by a mahram (Bukhari and Muslim).

Many hadiths deal with the prohibition of women traveling to perform Hajj, or for any other reason, without mahram. Because women are weak and may be confronted during the journey with difficulties or unforeseen events that only men can overcome. There is also the fact that woman is an object of covetousness on the part of evil people.Hence the importance that it is in the company of a mahram able to protect it.

 The mahram that accompanies the woman during her pilgrimage must be a Muslim, sane and pubescent. If it is impossible for her to find amahram , she can mandate a person of her choice to accomplish the Hajj in her place.

In the case of a Hajj, the woman must take her husband's permission, as he must give up (temporarily) his right over her. Moreover, the husband is entitled to prohibit him the supererogatory Hadj.

A man may mandate a woman to perform Hajj or Umrah in his stead. A woman can also perform it in the place of another woman, whether her daughter or not.
