If a woman has enough money to perform Hajj, it is obligatory upon her to do so. She is not advised to delay performing Hajj and should offer it as soon as possible. She may go in the company of trustworthy women who have their own mahrams (a non-marriageable male relative) or husbands, with whom her safety is assured.
Sheikh Muhammad Nur `Abdullah, former president of the ISNA (Islamic Society of North America) and member of the Fiqh Council of North America, states:
I don’t believe a woman has to wait until her husband can afford to accompany her. If she has a sufficient amount of money for her Hajj expenses, she can join a company of trustworthy and reliable Muslim sisters who are also going to perform Hajj. In this case, her husband can stay home with the children and allow his wife to go and fulfil her religious obligation. The problem that many people face is that they continue delaying it for ongoing reasons that do not seem to end. A Muslim never knows what might happen and when he is going to meet his Lord.
