" And tell the believing women to reduce (some) of their vision and guard their private parts and not expose their private parts and not expose their adornment except that which (necessarily) appears thereof and to wrap (a portion of ) their head covers over their chests and not expose their adornment except to their husbands, their husband's fathers, their sons, their husband's sons, their brothers, their brothers sons, their sister's sons, their women, that which their right hand possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers , that you may succeed."
