Ruling on reducing the hair of the eyebrows

If that is done by means of plucking, then it is haraam, and
indeed it is one of the major sins, because it is the “namas” for
which the Messenger (peace and blessings of Allaah be upon him) cursed
the one who does it. But if it is done by cutting or shaving, then it was
regarded as makrooh by some scholars and forbidden by others who regarded it
as a kind of “namas”. They said: “ ‘Namas’ does not only mean
plucking, rather it is a general word which includes all ways of changing
the hair for which Allaah has not granted permission, if it is on the face.”
But what we think is that women should not do that unless the hair of the
eyebrows is so thick that it hangs down over the eyes and affects her
vision, in which case it is o.k. to remove that which is causing the
problem.
