Ruling on bringing a servant without a mahram
Question

                I am a woman living in a non-Muslim country because of my husband’s work. I want to bring a servant from another country to help me in the house. Is it permissible for me to bring her without a mahram?.
Praise be to Allah.Bringing a servant without a mahram is an act 
    of disobedience towards the Messenger of Allaah  (peace and blessings of Allaah be upon him), because it was narrated in a saheeh report that 
    he said: “No woman should travel without a mahram.” And because bringing her without a mahram may be a cause of her being a source of fitnah 
    (temptation) and exposing her to fitnah herself. That which may cause fitnah is forbidden, because that which may lead to something haraam is also 
    haraam. 
With regard to the fact that some people take 
    this matter lightly, this is a calamity, and their saying that this is necessary does not count as proof, because even if we assume that it is 
    necessary to bring servants, it is not necessary to bring them without mahrams. Similarly the opinion of some of them that the sin of her 
    travelling without a mahram is on her shoulders or those of the company that brings servants into the country does not count as proof either, 
    because the one who makes it easy for another to do something haraam is a partner in the sin and in helping him to commit it. Allaah says 
    (interpretation of the meaning): 
“Help you one another in Al-Birr and 
    At-Taqwa (virtue, righteousness and piety); but do not help one another in sin and transgression”
[al-Maa’idah 5:2]
Allaah and His Messenger have commanded us to enjoin that which good and forbid that which is 
    evil. Bringing a female servant without a mahram is approving evil, not forbidding or denouncing it.
