That word ziina has been translated differnetly, some translate adornments, some translate charms, and in the trnaslation you quote it says beauty. "Adornmente seems to be the preferred term.
The thing is that in this aya there is no mistery, no big feat of engineering to awe the world. What it is talking about is about the most common of things. The same as 24.30.
Say to the believers (male), that they cast down their eyes and guard their private parts; that is purer for them. God is aware of the things they work. (30)
What is it saying? Is it so misterious? Do not look the way you shouldn't particularly to women. Is it a mistery what ould be purer for them? That they look respectfully and ithout invading th intimacy of anybody, particularly women.
God is aware of what they do.
Meaning do not put up a show as if you were behaving honourably when you know and God knows that in fact you are being shameless, for instance.
Don't we know what e are being tol? Do e want that there should be there something else, something that is unfathomable, misterious.
If you see what it says in aya 31 as con contrast with 30, women are not addressed as tu purity, seems that that is a orse danger for them males than for them females, but females are told not to make a show of themselves, not to expose themselves as a merchandise. They are not being given a list as to what they should dress ith but as to their baheaviour, mentality and outlook. They are not a merchandise, they are soverigns, they should not parade as if begging for anybody's attention. Just be normal. Just that, do not exhibit. Just be normal and do not feel that you should or could do better by exhibiting yourself.
Adn I mean exhibit, exhibit is not the same thing as that something is seen. Your face or whatever part of your body or your clothes or adornment may be seen but that is not calling anbyody's attention unless you exhibit it, or unless of course, there are the impure lookers finding what they are looking for by hook or crook.
Most of the Qur'an is not misterious when talks about behaviour. It is what e all kno, hat humans have always known. e are being reminded merely, because even if we kno, we tend to forget, to override because it is fashion, it is convenient or it is so easy. We are reminded. Women are sovereigns, not objects, they should have, for their own good, self-respect, not submit to be a show or beg for attention.
Males and females should respect themselves and their human dignity. It is not the details of apparel or dress or movements, but the outlook and mentality, should be of self-respect and respect for others.
As they say, do not look for noon at 4 in the afternoon.
