Muslim women covering their face will always be a hot topic and cause many controversies.
How do they eat?
The face covering can be lifted up, so to answer that question, lifting the niqab up and over your head is how it’s done. If there are people around, or more specifically, if there are men around, then they just lift it a little and stuff their face quickly.
Do they wear it at home?
No, they don’t. The niqab or face veil is to be worn, basically, in front of anyone they can marry. So they don’t have to cover themselves in front of their close family, grandfather, father, brothers, uncles etc. They can only dress western style in front of their girlfriends or go to parties and be skimpily dressed as long as it’s only women.
