Shaping eyebrows is probably the only thing that I have had numerous discussions about with friends and relatives. There are different kinds of reasons for people to do it but from what I gather it's mostly considered something so pettty that no thought is really put in that action, while on the other hand some people clearly know about the hadith of the Rasoolullah (peace and blessings be upon him) in which he curses the woman who shapes her eyebrows and the one who even does it. I myself have been put under pressure twice or thrice to really consider doing it because they are really big and oh well I still love them the way they are.
Moving on, there are even those who question the hadith by asking how come removal of upper lip hair is permitted while this is just mere shaping of an eyebrow. Some choose to explain that they do it because they want to look more appealing to their husbands and honestly All that men care about a woman's eyebrow is that she has a pair of it. Really, its just that much.
So a friend of mine made a wonderful poster that you can see above which goes well with what I really have to say all those peeps concerned with it ;)
