In a hadith Muhammad said that Satan occupies the space between people in communal prayer, the point being that people should stand together in communal prayer. Yet in my local mosque they stand 6 feet apart. When I asked someone about this, he said that health considerations override other requirements. I asked him how he knows that this is a real health issue. He answered that he asked the doctors in the mosque. I know this man and I know that he is much more intelligent than the doctors. He could easily do his own research but he would rather spend his time studying Islam instead. In my opinion, this is wrong. Muhammad stressed the need to balance religion with real world needs. Unlike the doctors, this man has the intelligence to see through Satan's lies. When God asks him on judgement day why he didn't invest the time to do this, I wonder what he will say. This story illustrates the core problem with Muslims today, namely their unwillingness to apply critical thinking that is needed to correctly apply Islamic principles to the modern world.
