Religion in Brunei

Among religions in Brunei, Sunni Islam is predominant. In 2021, the government census showed that 82.1% of Brunei's population is Muslim. However, other religions also have a considerable foothold in Brunei: 6.7% of the population is Christian and another 6.3% is Buddhist. The remaining 4.9% subscribe to various religions, including indigenous religions.

Islam is the state religion of Brunei. Freedom of religion and the right to practice privately are nominally guaranteed. Furthermore, some non-Islamic holidays, such as Lunar New Year, Christmas, Vesak day and Gawai Dayak, are recognised. These rights, however, are limited in practice: religious education is controlled, even in the Chinese, Christian and private schools. Brunei's penal code criminalizes efforts to promote religions other than Islam to Muslims or the non-religious, including persuading religious conversion, exposing Muslim children to other faiths, or opposing Islamic authorities. It also punishes those who assist in such acts. These provisions marginalize non-Muslims and non-believers, severely restricting their religious freedom in violation of international human rights standards. Non-Muslims must be at least 14 years and 7 months old if they want to convert to another religion. A minor will automatically become a Muslim if their parents convert to Islam.

The state madh'hab of Islam is the Shafi'i school of jurisprudence of Sunni Islam. Most of Brunei's Muslim population subscribe to the Shafi'i school as well, and Shafi'i is a major source of law for the country. However, with the Sultan's permission, lawmakers may also consult the other three Sunni schools of fiqh.
