The Malaysian constitution guarantees freedom of religion while making Islam the state religion. According to the Population and Housing Census 2010 figures, ethnicity and religious beliefs correlate highly. Approximately 61.3% of the population practice Islam, 19.8% practice Buddhism, 9.2% Christianity, 6.3% Hinduism and 1.3% practice Confucianism, Taoism and other traditional Chinese religions. 0.7% declared no religion and the remaining 1.4% practised other religions or did not provide any information.
All ethnic Malays are considered Muslim by law of the Constitution. Statistics from the 2010 Census indicate that 83.6% of the Chinese population identify as Buddhist, with significant numbers of adherents following Taoism (3.4%) and Christianity (11.1%), along with small Hui-Muslim populations in areas like Penang. The majority of the Indian population follow Hinduism (86.2%), with a significant minority identifying as Christians (6.0%) or Muslims (4.1%). Christianity is the predominant religion of the non-Malay bumiputra community (46.5%) with an additional 40.4% identifying as Muslims.
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. The jurisdiction of Shariah courts is limited 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 do not hear matters related to Islamic practices
