The difference is that Quran is not taught in management school, Islamic scholars are not called in universities for debate, Judges and space scientist do not go Muslim scholars to seek their guidance for how to deliver justice or to solve riddles in space mission. Quran does not have the maths, Quran does not preach how to build super buildings which lasts for thousands of years. Quranic practices are not recognized and taught across the world for mental and physical wellbeing. If you sideline your commie bias and let your brain, think neutrally, it is not very difficult to visualize the difference.
