Is it permissible to uncover the face if wearing the niqab leads to problems, with the intention of wearing it when the opportunity arises?

Scholars have differed regarding the permissibility of a woman uncovering her face in front of non-mahram men when there is no fear of fitnah (temptation). The relied-upon opinion with us is that it is impermissible and that a woman must cover her entire body.

If you believe it is permissible to uncover the face when there is no fear of fitnah, then there is no blame upon you for uncovering it if you are safe from fitnah.

However, if you believe that covering the face is obligatory, then it is not permissible for you to uncover it unless there is a certain harm upon you in doing so. In this case, you should limit your going out to what is necessary.
