I have not met 1 Muslim who states the same you do.
Probably because I'm a Baha'i, not a Muslim.
How much of Sharia law works for today? There are reformers in Islam of course.
In the modern era, sharia-based criminal laws have been widely replaced by statutes inspired by European models. Judicial procedures and legal education in the Muslim world were likewise brought in line with European practice. While the constitutions of most Muslim-majority states contain references to sharia, its classical rules were largely retained only in personal status (family) laws. Legislative bodies which codified these laws sought to modernize them without abandoning their foundations in traditional jurisprudence. The Islamic revival of the late 20th century brought along calls by Islamist movements for full implementation of sharia, including reinstatement of hudud corporal punishments, such as stoning. In some cases, this resulted in traditionalist legal reform,while other countries witnessed juridical reinterpretation of sharia advocated by progressive reformers.
