Burqa represents modesty, piety, and cultural identity.

Below is the Quran verses on covering the body and women should not display their beauty:

“And tell the believing women to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts, etc.) and not to show off their adornment except only that which is apparent (like palms of hands or one eye or both eyes for necessity to see the way, or outer dress like veil, gloves, head-cover, apron, etc.), and to draw their veils all over Juyubihinna (i.e. their bodies, faces, necks and bosoms, etc.) and not to reveal their adornment except to their husbands, their fathers, their husband’s fathers, their sons, their husband’s sons, their brothers or their brother’s sons, or their sister’s sons, or their (Muslim) women (i.e. their sisters in Islam), or the (female) slaves whom their right hands possess, or old male servants who lack vigour, or small children who have no sense of the shame of sex. 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.” (Quran 24:31)

It’s natural for men n women to get attracted to each other…
Man’s thinking is different from women’s thinking.

Women’s are shy by nature and mentally strong…even if they get attracted to men, they don’t approach them and  ask them for coffee or movie …but when men gets attracted towards women, they approach them n ask them for coffee or movie or lunch…

So, when a Muslim women wear burqa, they are indirectly saying she is not approachable n not interested in going out with men…

Burqa is a kind of religious covering for protection of women from lustful eyes, molestation n sexual desires of a man…

It also save men from committing sin like giving lustful look, indulge in Fornication etc..
