Q "Are you going to church today in honor of the Sun god Tammuze?" ================================================
Muslims believe God is omnipotent and as such He doesn't need rest. You might like to correct that if you don't think it makes sense. So Muslims don't have a Sabbath or day-of-rest concept. They go to their churches [mosques] everyday. They do it in honour of their creator and the creator of all that exists, the one who sent Noah, Abraham, Moses, Jesus, Mohammed and thousands of others before to every people that ever existed so that people may know Him and follow His guidance and get not lost following only their own whims and desires or of those who want to exploit them.
