Hijab is the most visible symbol of Islam, and is often referred to as the head dress used by a Muslim woman to cover her head.
The term "hijab" literally means a cover, curtain or screen. The term is used in Islamic jurisprudence that denotes the conduct of unrelated men and women towards one another, and their dress code.
