The classical Islamic position, based on hadith, is that a woman should not travel the distance requiring shortening namazs without a mahram — a male relative she cannot marry. This includes her father, brother, son, husband, uncle, nephew, or grandfather. Hz. Peygamber (sallallahu aleyhi ve sellem) said: 'No woman should travel except with a mahram.' However, scholars have differed on whether this applies specifically to Hac when it becomes farz.
Saudi Arabia has progressively relaxed its administrative requirements. Women aged 45 and above can now perform Hac without a mahram if they travel as part of an organized group with other women. Some countries have further relaxed these requirements, allowing women of any adult age to apply for Hac without a mahram, provided they travel with a licensed group.
Among the four schools of jurisprudence, the Shafi'i and Maliki schools allow a woman to perform the farz Hac without a mahram if she travels with a trustworthy group of women or trustworthy companions, particularly when the obligation of Hac would otherwise go unfulfilled. The Hanafi and Hanbali schools traditionally require a mahram for any journey of this nature. Women should consult their local Hac authority for the most current rules in their country.
