Well, to be fair, some Muslim sects have various rites that often involves going outside.

Like the one where the men take their shirts off and flog themselves in a big group, in public, until they bleed & stuff. Yeah they were allowed to do this during Covid-19.84 lockdowns, but Christians couldn't meet AT ALL.

Note: being shirtless in public is generally 'haram' even for the men, eh?

But 99% of the time? Things like this are done just to piss infidels off 😡
