Why do Muslim scholars spend a lot of time talking about Jahili society (the Pre-Islamic Period of Ignorance)? Because it was a great miracle that Muhammad (ﷺ) could change these people within a portion of his earthly life, this is unheard of (even Western Secularists, with over 300+ years have not been able to totally change the moral fabric of their own societies towards goodness, let alone that of the rest of the world – yes they have shifted evil into legal ways and have basically redefined many terms to suit a different type of lifestyle, but that is mostly it).
