Quran 24:31. And tell the believing women to restrain their looks, and to guard their privates, and not display their beauty except what is apparent thereof, and to draw their coverings over their breasts, and not expose their 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, what their right hands possess, their male attendants who have no sexual desires, or children who are not yet aware of the nakedness of women. And they should not strike their feet to draw attention to their hidden beauty. And repent to God, all of you believers, so that you may succeed.​

There is only one verse today.... there is "so much commentary" on that one verse.... I had to pull it out by itself.

Here's the commentary.

To guard the relations between males and females and to check a too free intermingling of men and women, the Qur’ån now lays down another injunction in addition to that which requires both sexes to lower their gaze when they meet each other. It requires women in particular not to display their adornment. There is a difference of opinion as to what zßnat means. According to some it includes the beauty of the body, while according to others it is exclusively applied to external adornments. The use of the same word in the concluding portion of the verse, let them not strike their feet so that the zßnat that they hide may be known, clearly supports the latter view, as the only adornment that can be known by the striking of the feet consists of external ornaments. But even taking the first view, there is a clear exception here, illå må ˚ahara min-hå — except what appears thereof or except that which it is customary and natural to uncover. Now in the first place it must be remembered that what is prohibited is the display of beauty, as elsewhere expressly indicated by the word taburruj: “And display not (your beauty) like the displaying of the ignorance of yore”. As to what parts of the body the woman is required to cover and what she may uncover the following summary of the earlier views relating to this exception given by IJ should suffice: (1) it means the adornment of dress or the clothes that a woman wears; in other words, she is not required to cover the clothes she wears; (2) it means the adornment which the woman is not required to cover, such as collyrium, rings, bracelets and her face; (3) the exception relates to a woman’s clothing and her face. After relating these opinions, IJ adds: The most correct opinion is that the exception relates to the face and hands. As an argument corroborating this opinion he says that, when praying, the woman is not required to keep her face and hands covered — hands up to the elbow — while she is required to cover the rest of the body. According to Ïadßth, the Prophet himself is reported to have told Asmå’, his wife ‘Å’ishah’s sister, when she appeared before him in thin clothes, through which parts of her body could be seen: “O Asmå’, when woman attains her puberty it is not proper that any part of her body should be seen except this, and he pointed to his face and hands”. This settles conclusively that Islåm never enjoined the veil or covering of the face.​
