Muslim religion is a savage, brutal works religion. But rather than bash or degrade them we as Christians should tell them about Christ the lord. God is love and we can rest in him. His name is Jesus Christ the Lord. He is even the Lord of the heathen and the whole world. Every knee shall bow and every eye shall see.
For there is none other name under heaven given among men whereby we must be saved....Acts 4:12
As Christians it is our honor and privilege and duty to tell others about the one true God. And so to our so called Muslim friends, come to Christ, turn from your ways and Rest . Who knows if God will bring them out from where they are and have mercy on some of them. If we witness to them in the love of Christ, we have done our part and God will do the rest.
"So shall my word that goeth forth out of my mouth: it shall not return void but it shall accomplish that which I please and it shall prosper in then thing were to I sent it"
Come to Christ and rest from your works in him the only true God and Salvation. There is no other way.
