What is the ruling on a woman taking off her niqab after wearing it for ten years, especially if she is in her forties?

The ruling on the niqab is a confirmed شرعي (religiously legal) one for all times. Its obligation is further emphasized in this era due to the corruption of people and the scarcity of religious deterrence. It is incumbent upon anyone who has abandoned it to repent to Allah and return to wearing it, and to beware of abandoning it in the future, for wearing it is more protective of her religion and her honor.
