Asalaamualaykum I hope you are well. I am volunteering for my local masjid. We have a few individuals who refuse to wear a mask and bring a pray mat with them. They have been told several times but they for some reason still refuse.
They say stuff like we don’t need to wear it, it’s all kufar rules etc, have trust in Allah.
Can we refuse entry to them because other are seeing and copying.
Is protective measure against trust in Allah?
Should we be doing this?

Please kindly guide us to the path of moderation.
Jazkallah khair
