Ruling on taking off hijaab when travelling abroad
Question

                What is the ruling on taking off hijaab and uncovering the face when traveling abroad in obedience to my mother’s demands, on the grounds that I attract unwelcome attention?
Praise be to Allah. 
          It is not permissible for you or for 
          any other woman to take off your hijaab in the kaafir countries, just 
          as that is not permissible in any Muslim country. It is obligatory to 
          observe hijaab in front of non-mahram males whether they are Muslims 
          or kaafirs; indeed it is more obligatory in the case of kaafirs, because 
          they have no faith to keep them from doing that which Allaah has forbidden. 
 
          It is not permissible for you or any 
          other woman to obey parents or anyone else in doing that which Allaah 
          and His Messenger 
          
          (peace and blessings of Allaah be upon him) have forbidden. Allaah says 
          in Soorat al-Ahzaab (interpretation of the meaning): 
 
          “And when you ask (his wives) for anything 
          you want, ask them from behind a screen, that is purer for your hearts 
          and for their hearts”
 
          [al-Ahzaab 33:53]
 
          In this aayah Allaah explains that for women to observe 
          hijaab and be screened from non-mahram men is purer for the hearts of 
          everyone. And Allaah says in Soorat al-Noor (interpretation of the meaning):
 
          “And tell the believing women to lower 
          their gaze (from looking at forbidden things), and protect their private 
          parts (from illegal sexual acts) and not to show off their adornment 
          except only that which is apparent (like both eyes for necessity to 
          see the way, or outer palms of hands or one eye or dress like veil, 
          gloves, headcover, apron), and to draw their veils all over Juyoobihinna 
          (i.e. their bodies, faces, necks and bosoms) and not to reveal their 
          adornment except to their husbands, or their fathers, or their husband’s 
          fathers…”
 
          [al-Noor 24:31]
 
          And the face is the greatest part of 
          beauty or adornment.
