Outside of Saudi Arabia, I am not sure which Muslim country follows the Sharia law. The UAE, where I lived, had a mixture of Islamic and French law. Pakistan has a mixture of Islamic and British Law. So does Egypt, Bangladesh, etc. The Stans of Central Asia follow Soviet Law only. Indonesia doesn't follow Sharia Law either. Neither does Turkey.In India the 180 million Muslims follow a British inspired civil code.

The countries that I have mentioned form over 90 percent of the world's Muslim population.
