Malaysia is a multi-religious society, but while the Malaysian constitution theoretically guarantees freedom of religion, Islam is the official religion of the federation, as well as the legally presumed faith of all ethnic Malays. No ethnic Malay is allowed to leave Islam, while non-Malay Muslims seeking to apostacise require permission from a sharia court, which is rarely granted. Religious beliefs follow ethnic lines. Holidays have been declared for holy days in numerous religions, although only Islam has more than one national holiday. Whether a religion obtains approval of the government is determined by the Registrar of Societies, part of the Ministry of Home Affairs. Only upon approval do they qualify for government benefits. However, unrecognised groups such as the Falun Gong can practise by registering themselves under the Companies Act, although this means that technical violations of the act can result in a fine.
