What is the ruling on wearing the niqab, and is it obligatory? What is the response to its exploitation in crimes? And does the hijab alone harm women?

The fact that corrupt and criminal individuals conceal themselves with the niqab does not negate its obligation. Rather, it is incumbent upon Muslims to adhere to it and to apprehend those who spread corruption. The abandonment of the niqab and the unveiling of women have led to corruption and crimes. Adherence to the Sharia-compliant niqab preserves society and cuts off the roots of evildoers. What has afflicted Muslims has not been due to adherence to the Sharia, but rather due to its abandonment.
