She wants to travel for Hajj with a group but without a Mahram
Question

                Iam the only child to my parents. Iam
      married and have only two daughters.My husband and I live in the USA, and all our families
      and relatives live in a country in the middile east. Thus the only Mahraam I have is my
      husband who cannot travel out of the USA for reasons that I cannot mension in this email.
      I really whant to go to Hajj inshaa-Allah since I have all the means to do so. Is it Halal
      for me to go to Hajj with an organized group for pilgrims. And if not, how will I ever be
      able to fullfil this important pillar of Islam when I don't have any Mahrams?!
Praise be to Allah.A woman does not have to go for Hajj unless she is able,
    and having a Mahram who can accompany her is one of the prerequisites for her to be able
    to go to Hajj. If it is not easy for her to find a Mahram to go for Hajj with her, then
    she is not able according to Shareeah, because in Islam a woman is forbidden to
    travel without a Mahram. Therefore Hajj is not obligatory for you unless you find a
    Mahram. So have patience until Allaah makes it easy for you to have a Mahram with whom you
    can go for Hajj. You have a valid excuse and there is no sin on you for this. As for going
    with a group without a Mahram, this is not permissible because of the hadeeth narrated by
    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 a woman unless her Mahram is with her. A man said,
    O Messenger of Allaah, I want to go out with such-and-such an army and my wife wants
    to go to Hajj. He said, Go to Hajj with her. (Reported by
    al-Bukhaari, 1729). The pilgrims used to go out from Madeenah in one
    caravan like a group but still the Prophet 
 (peace and blessings of Allaah be upon him)
    did not allow women to travel without a Mahram.
    And Allaah knows best.
