Mahram and Umrah

Q: My husband doesn't pray. I want to take him on umrah but he said no. I have no other mahram. What can I do?

A: It is indeed a great act on your part to offer to take your husband for Umrah. Whether he prays his salaah or not, it is his duty to accompany you as a mehram. However, if he refuses to go with you, you cannot force him. The alternative would be to either look for another mehram, such as your brother, father, uncle, nephew, or son (if you have a baaligh son), or else postpone your umrah for another date.
A woman is not allowed to travel without her husband or a mehram. This ruling is mentioned in many hadith of our Rasool (sallallahu alayhi wasallam).
