An-Noor 24:31

Tell the believing women to lower their gazes and guard their private parts, and not to reveal their beauty[19] except what appears[20]. And let them draw their veils over their chests, and not to reveal their beauty[21] except to their husbands, their fathers, their fathers-in-law, their sons, their stepsons, their brothers, their brothers’ sons or sisters’ sons, their fellow women, slaves whom they own, male attendants who have no [sexual] desire[22], or children who are still unaware of private aspects of women. Nor let them stamp their feet in order to draw attention to their hidden charm. And turn to Allah in repentance all together, O believers, so that you may be successful.

[19] Both natural beauty such as hair and body shape, and other beauty such as clothing, jewelry, etc. [20] i.e., outer garments, etc. [21] i.e., hair, neck, arms, legs, etc.
[22] An abnormal condition where a man is devoid of sexual feelings.

And tell the believing women to reduce [some] of their vision[990] and guard their private parts and not expose their adornment[991] except that which [necessarily] appears thereof[992] and to wrap [a portion of] their headcovers over their chests and not expose their adornment [i.e., beauty] except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons, their women, that which their right hands possess [i.e., slaves], or those male attendants having no physical desire,[993] 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 Allāh in repentance, all of you, O believers, that you might succeed.

[990] Looking only at what is lawful and averting their eyes from what is unlawful.
[991] Both natural beauty, such as hair or body shape, and that with which a woman beautifies herself of clothing, jewelry, etc.
[992] i.e., the outer garments or whatever might appear out of necessity, such as a part of the face or the hands.
[993] Referring to an abnormal condition in which a man is devoid of sexual feeling.

31. And tell the believing women to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts) and not to show off their adornment except only that which is apparent (like both eyes for necessity to see the way, or outer palms of hands or one eye or dress like veil, gloves, head-cover, apron, etc.), and to draw their veils all over Juyûbihinna (i.e. their bodies, faces, necks and bosoms) 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 (Muslim) women (i.e. their sisters in Islâm), or the (female) slaves whom their right hands possess, or old male servants who lack vigour, or small children who have no sense of feminine sex. And let them not stamp their feet so as to reveal what they hide of their adornment. And all of you beg Allâh to forgive you all, O believers, that you may be successful.[3]

[3] (V.24:31) "And to draw their veils all over Juyûbihinna (i.e. their bodies, faces, necks, and bosoms) and not to reveal their adornment..."
Narrated ‘Âishahرضي الله عنها: ‘May Allâh bestow His Mercy on the early emigrant women. When Allâh revealed:
"And to draw their veils all over Juyûbihinna (i.e. their bodies, faces, necks, and bosoms)" - they tore their Murût (a woollen dress, or a waist-binding cloth or an apron, etc.) and covered their heads and faces with those torn Murût’
Narrated Safiyyah bint Shaibah: ‘Âishah used to say: ‘When the Verse:
"And to draw their veils all over Juyûbihinna (i.e. their bodies, faces, necks, and bosoms)" (V.24:31) was revealed, (the ladies) cut their waist sheets at the edges and covered their heads and faces with those cut pieces of cloth.’ (Sahih Al Bukhari, Vol.6, Hadith No.282).

And tell the believing women to lower their gaze and be modest, and to display of their adornment only that which is apparent, and to draw their veils over their bosoms, and not to reveal their adornment save to their own husbands or fathers or husbands' fathers, or their sons or their husbands' sons, or their brothers or their brothers' sons or sisters' sons, or their women, or their slaves, or male attendants who lack vigour, or children who know naught 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 together, O believers, in order that ye may succeed.
