Sharia law is the most important part of Islamic doctrine. Sharia is Islam; Islam is Sharia. Sharia includes law, but it also includes how to raise a family, theology, philosophy and every aspect of daily living. Sharia law includes pronouncements for both Muslims and non-Muslims (Kafirs). Sharia is a manual for a civilization.
Sharia does not allow free speech. It is forbidden to make a joke about Mohammed. Blasphemy is forbidden. The US is following Sharia when it allows the UN to determine that Muslim refugees come to America and not Christians.
We have Sharia compliant textbooks now in Tennessee. We hesitate to anger Muslims or criticize Islam. In Europe Islamic rape is accepted behavior.
Sharia says that our Constitution is manmade and a product of ignorance. Sharia is Allah’s law and must replace all other governments. Countries that adhere to all of Sharia are Saudi Arabia, Afghanistan and Yemen.
