How should the Niqab look like? Should it be a really small space where the gap is really small, almost not visible if looked at. What about women with glasses? Are Niqabs where one sees the surroundings around the eyes wrong like some sisters wear?

Ustadh AbdulAziz al-Haqqan
There will be holes for the eyes without showing the cheeks and without showing the eyebrows. That's it. And she can wear the glasses on the niqab.
