O Prophet! Tell your wives and your daughters and the women of the believers to draw their Jalabib[outer garments] over their bodies.That will be better that they should be known so as not to be annoyed. And Allah is Ever Oft-Forgiving, Most Merciful.
{Al-Quran 33:59}
And tell the believing women to lower their gaze, and protect their private parts and not to show off their adornment except that which is apparent, and to draw their veils all over their Juyub and not to reveal their adornment except to their husbands, or their fathers, or their husband's fathers, or their sons, or their husband's sons, or their brothers or their brother's sons, or their sister's sons, or their women, or their right hand possessions, or the Tabi`in among men who do not have desire, or children who are not aware of the nakedness of women.And let them not stamp their feet so as to reveal what they hide of their adornment.And all of you beg Allah to forgive you all, O believers, that you may be successful. {Al-Quran 24:31}
