What is a burqa?
The name varies according to country, custom, and time: burqa, niqab, veil, chadari, abaya: effectively it is a one-person mobile tent with either an opening for the eyes or a lighter fabric to let the woman inside see through.
In countries where the burqa is required by law or imposed by male violence and female policing of the woman’s “honour”, adult women sometimes suffer from Vitamin D deficiencies because their skin may never get direct sunlight.
There is no requirement in the Qu’ran for Islamic women to cover their faces or to tent themselves with fabric in a burqa or chadoor.
The Islamic requirement that does exist, that believing men and women should dress and behave modestly, is culturally applied to women, and this double standard has been discussed at length by Muslims and non-Muslims. (I’d note that neither Islam nor any other religion nor the secularist community is unique in having double standards of behaviour and requiring women to behave to standard or face cultural punishment.)
