A hijab is a religious veil worn by Muslim women in the presence of any male outside of their immediate family, which usually covers the hair, head and chest. The term can refer to any hair, head, face, or body covering worn by Muslim women that conforms to Islamic standards of modesty. Hijab can also refer to the seclusion of women from men in the public sphere, or it may denote a metaphysical dimension, for example referring to "the veil which separates man, or the world, from God".
