Hijab
The word , or a derivative, appears eight times in the Qur'an and never connotes any act of piety or headscarf. It appears as an "obstacle" (7:46), a "curtain" (33:53), "hidden" (38:32), a "wall of separation" (41:5, 42:52, 17:45), "hiding" (19:14) and "prevented" or "denied access to God" (83:15).
