In the early days of Islam, covering the hair was assumed only by the socio-economic elitist women of Arabian society. Women were treated very differently from each other because their social status was consequently self-evident. Here's the wisdom, if all women in that society covered their hair, then you couldn't tell who was higher or lower on the social ladder. Then, all women had to be treated with respect, or else you get slapped! The head scarf elevated the social status for women in a society. I know this because of the ongoing fashion controversy among prostitutes in Kenya's coastal port of Mombasa. Prostitutes have donned the buibui to hide their identity and avoid arrest, but it clashes with the Muslim women who wear it for religious reasons.
Back in the States, we still have not moved beyond judgment on superficial levels or judgment at all for that matter regarding hijab. Take our MSA's (Muslim Student Association) for example, if you ain't part of the hijab crowd you ain't part of the IN crowd. Yes it is obvious to us male observers with Muslim female friends. Seriously it's sad.
Let me tell y'all something. ANYONE can wear a scarf on their head. You don't even have to be a Muslim. Anyone can go through the motions of prayer, the motions of fasting, the motions of whatever, but it comes down to what is in the hearts and the intentions, the things we can't see in each other. Tell me why there should be a standard Islamic dress code, a uniform, if you get situations like the Muslim juror who got arrested for listening to her iPod underneath her hijab during a murder trial.
Modesty, good behavior, and respect for yourself. Word to my Muslim sisters, if wearing a scarf brings you closer to God, I support you. If something else brings you closer to God which has nothing to do with the way you dress, I support you. If you are still looking for that something that brings you closer to God, hey I support you too.
You'll get the same treatment from me if you wear a scarf on your head or you don't.
