Sharia Law which is the Law of Islam is complete counter indicative of the United States Constitution, SEE BELOW:
Sharia law is the law of Islam. The Sharia (also spelled Shariah or Shari'a) law is cast from the actions and words of Muhammad, which are called "Sunnah," and the Quran, which he authored.
The Sharia law itself cannot be altered, but the interpretation of the Sharia law, called "figh," by imams is given some leeway.
As a legal system, the Sharia law covers a very wide range of topics. While other legal codes deal primarily with public behavior, Sharia law covers public behavior, private behavior and private beliefs. Of all legal systems in the world today, Islam's Sharia law is the most intrusive and strict, especially against women.
According to the Sharia law:
• Theft is punishable by amputation of the right hand (above).
