The religion of Islam doesn't say Muslim women must cover their faces. It's not a requirement of the religion of Islam. It's not a part of the religion. 

And many Muslim women don't cover their faces in public.

And some Muslim countries, like Azerbaijan, Egypt, Tunisia and Turkey, don't allow women to wear niqabs to cover their faces.

And Saudi Arabia doesn't let Muslim women wear niqabs to cover their faces while on the Haj in Mecca. Wouldn't that be the time place to practice Islam?

So, if covering the face is not a part of or a requirement of the religion of Islam, how can Muslims argue it's a religious right in Canada?

Maybe the courts in Canada should finally make a decision whether the religion of Islam really requires Muslim women to cover their faces.
