Shariah is applicable on the lives of all Muslims, while regions where the majority of the population is Muslim are governed by the Shariah laws. The aspects of the legislative framework that are governed under the Shariah law include Islamic banking, Islamic Commercial Law, inheritance, politics, economics, contracts, business, as well as social issues.
Aside from this where other alternative legislative systems are present, the Shariah can be used a source of Islamic legislature for Muslims from which the regional legislature can be derived through Islamic jurisprudence of prominent scholars and clerics of the religion. There exists only one country in the world,Saudi Arabia, where Shariah is employed in its essence as the law of the state.
. “In the Islamic tradition Sharia is seen as something that nurtures humanity. They see the Sharia not in the light of something primitive but as something divinely revealed. In a society where social problems are endemic, Sharia frees humanity to realize its individual potential.” (Sharia, BBC Religion and Ethics – Islam, 2009)
