Sometimes i hate muslim women without hijab but some are very kind,it's ok?

I think perhaps you are reacting as a lot of people in your country would react. I am not muslim and really don't know much about your customs and traditions. I am wondering however why women have to wear these? What is it meant to signify? Just because a woman covers or doesn't cover her head really has nothing to do with what type of person you are so I cannot understand why someone would be upset by them not doing it. Please enlighten me.

I guess I can understand the feeling. Yeah, many Muslims nowadays forget that wearing covers is a will of Allah. Though we can only remind them actually. Our responsibity is to remind them, that's all. The relationship of human in Islam can be categorized as three: Relation between human and Allah, between human and another human, and between human and nature. Relation between human and Allah, for examples, the daily prayers, fasting, being grateful to Him, anything that connect between human and Allah, the responsibilities to Allah. Wearing covers is also this type of relation. So, whenever a person decided to wear covers or not, it's their choice and no one can't force them, as if no one can force other to pray to Allah, to believe in Allah etc, but they must realize that it is the will of Allah. If they refuse, we as another human can only remind them, any judgement would be at the hand of Allah.
