Muslims are obliged to follow the decisions of Syariah courts in matters concerning their religion. The Islamic judges are expected to follow the Shafi`i legal school of Islam, which is the main madh'hab of Malaysia. These courts apply Sharia law. The jurisdiction of Shariah courts is limited only to Muslims in matters such as marriage, inheritance, divorce, apostasy, religious conversion, and custody among others. No other criminal or civil offences are under the jurisdiction of the Shariah courts, which have a similar hierarchy to the Civil Courts. Despite being the supreme courts of the land, the Civil Courts (including the Federal Court) do not hear matters related to Islamic practices. Cases concerning a Muslim and a non-Muslim are usually handled by the civil courts, although in cases such as child custody or property settlement the non-Muslim has no say.
