Here is how sharia law looks like when it becomes the law of the land within a country.
The body of 11-year old Christian boy named Samuel Yaqoob was located at the end of the Eid-Ul-Fitr holiday on August 20. His remains were discovered in Faisalbad with his lips and his nose cut off from his face. He was also disemboweled and his legs were mutilated. Then, the body was burned.
The reason that this child was killed by Muslims is because of sharia law that permeates throughout the land of Pakistan. Now, you're starting to see why the US keeps drones in Pakistan on a daily basis.
Within sharia law, anyone who blasphemes Islam could face the death penalty. This concept is stated numerous times in various Muslim texts such as the Koran and the Sahih al-Bukhari.
