Muslim mother with 2 toddlers wear Niqabs to prevent Muslim men from being tempted.
The whole idea of the hijab (and niqab) is that it is entirely the woman’s responsibility to prevent men from being tempted. She must cover herself in order to forestall that temptation.
In countries such as Iran and Saudi Arabia, the Islamic veil symbolizes oppression of women under Sharia law.
Women who remove the veil are publicly flogged almost to death by the Sharia police.
