I dont know how to insert a link so I cut and pasted the following from www.quraan.com (hope I am allowed to do that?).
And tell the believing women to lower their gaze and guard their private parts from sin and not show of their adornment except only that which is apparent, and draw their headcovers over their necks and bosoms and not reveal their adornment except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, or their brothers' sons, or their sisters' sons, or their women (i.e., their sisters in Islam), or their female slaves whom their right hands possess, or old male servants free of physical desires, or small children who have no sense of women's nakedness. And let them not stamp their feet so as to reveal what they hide of their adornment. And turn unto Allah altogether, O you Believers, in order that you may attain success.[An-Nur, 24:31]
The word zeenah in the aayah above, literally means "adornment", and includes both (a) that which Allah has adorned, i.e., the woman's natural and/or physical beauty, and (b) that with which they adorn themselves, i.e., jewelry, eye shadow, attractive clothing, hand dye, etc. Soorat An-Nur spells out specifically the commands concerning the fact that a woman's natural beauty and her adornments are to be concealed from strangers except by (1) What may show due to accidental or uncontrollable factors such as the blowing of the wind, etc., and (2) What has been exempted (see explanation at end of this section). Allah also says:
O Prophet, Tell your wives and your daughters and the women of the believers to draw their outer garments about themselves (when they go out). That is better so that they may be recognised and not molested. And Allah is Forgiving, Merciful. [Al-Ahzaab, 33:59]
Abu Dawood narrates that `Aishah (RAA) said: "Asmaa' the daughter of Abu Bakr (RAA) came to see the Messenger of Allah (SAAWS) wearing a thin dress; so Allah's Messenger (SAAWS) turned away from her and said: O Asmaa', once a woman reaches the age of menstruation, no part of her body should be seen but this-and he pointed to his face and hands.
This is certainly what I have been taught and what both of my Qurans say, no mention of covering the face and the Hadith from Abu Dawood is accepted as authentic is it not?
