^I don't know, I'll get back to you later, but there is a difference between laws applied to whole society and the laws applied to individual. In matters of individual laws, no one can be forced to do it; so from that perspective hijab falls under that category. However, to avoid greater harm and corruption within society, those laws can be enforced on people form the ruler; so from that perspective hijab would fall under bringing justice within society. Last but not least, the laws can only be enforced by the ruler and not by individuals. For example, a father cannot force her daughter to wear hijab rahter his job is educate her and remind her of her obligations toward her Creator.

I'll post the definite anwer to your question later or wait for someone else to respond

and Allah knows best
