&gt; The only laypeople who use the Koran and Hadiths as sources for direct personal understanding of Islam are literalist Salafist&#x2F;Wahhabist types including ISIS and Al-Qaeda.<p>And Saudi Arabia which finances with billions (?) of dollars the religious education of Muslims around the world? Even in the Muslim religious education in the countries which don&#x27;t use Sharia the first thing the kids learn is to differentiate themselves from unbelievers.<p>Then even as the layperson you can easily count how many statements there are in the holy book in which the Unbelievers are &quot;liers&quot; and will be &quot;painfully punished&quot; for which is &quot;fire&quot; etc. It&#x27;s not written in parables or anything it&#x27;s completely and plainly explicit.<p>Ditto for the practices of stoning, beheading in Sunnah etc.<p>The layperson doesn&#x27;t have to practice Islam, or know their religious discussions to get the rough idea of the content.
