Among non-mahram men, women must cover the parts of the body that are awrah (not meant to be exposed). In much of Islam, a women's face is not considered awrah. In Saudi Arabia and some other Arab states, all of the body is considered awrah except the hands and eyes. Accordingly, most women are expected to wear the hijab (head covering), a full black cloak called an abaya, and a face-veil called niqab. Many historians and Islamic scholars hold that the custom, if not requirement, of the veil predates Islam in parts of the region. They argue that the Quran was interpreted to require the veil as part of adapting it to tribal traditions.
