I've been seeing alot of different information about hijab styles and have been seeing alot of judgemental comments about not wearing the 'right' hijab. Of course, some follow hadiths and sunnah but for me, there are two main points. One, the Quran doesn't state exact specifications of how to wear hijab- only to be modest and cover the bosom. I believe this is meant to provide muslimahs with the free will to determine how they want to honor Allah- whether its with no head covering or a hijab that covers only hair or covers the neck and hair. Two, I know some follow the Sunni/Shitte ways of Islam, but no person has the right to judge- they may feel hijab should be worn a certain way but that is their view of Islam and not universal: we all have our own path to Allah. Bottom line- we shouldn't be talking about others.

[these are similar styles to how I've worn hijab lately]
-My own take is that as long as I feel I am wearing hijab in a manner that is honoring Allah [modest] and do not feel uncomfortable with how I'm wearing it [as in is it too exposing] then I will wear it in a different style. Lately, I have worn it spanish wrap style with some neck exposed and immediatley my husband says 'you're showing too much this and that"- despite the fact that he freaked out about me wearing hijab in the first place. If I feel I am obeying Allah, I can't allow other's judgements to sway me. I like the variety and will still be cognizant of being modest and wearing hijab to submit and honor Allah.
