Malaysia is a multi-religious society, but Islam is the official religion of the country. The four main religions are Islam , Buddhism, Hinduism, and Christianity (mostly in East Malaysia). Until the 20th century, most practiced traditional beliefs, which arguably still linger on to a greater degree than Malaysian officialdom is prepared to acknowledge.
All of the world's major religions have substantial representation in Malaysia, the main adherents of each largely reflecting the multi-ethnic character of the population. The variety of religions found in Malaysia is a direct reflection of the diversity of races living there.
Although Islam is the national religion of Malaysia, freedom of religion is guaranteed. The Malays are all Muslims. The Chinese embrace an eclectic brew of Taoism, Buddhism and ancestor worship, though some are Christians. Although Christianity has made no great inroads into Peninsula Malaysia it has had a much greater impact upon East Malaysia, where many indigenous people have converted to Christianity , although others still follow their animist traditions.
Islam
Islam is the national religion of Malaysia. Islamic mosques in Malaysia generally have a domed ceiling for the main prayer hall and a tall minaret from which the call to prayers is broadcast five times a day. In many places around the city, you will likely hear the call to prayers coming from one (or more) mosques.
Many of the mosques accept visitors and are well worth a tour, though all will ask you to respect the customs. Suitable dress is required, and if you are female or a non-Muslim, you may not be permitted into all areas of the mosque.
Masjid Negara (National Mosque) on Jalan Sultan Hishamuddin was built in 1960 and is one of the largest mosques in South-East Asia, able to accommodate 8,000 worshipers at any one time.
Buddhism
Buddhism is the predominant religion for many Malaysian Chinese, and the Buddhism temples found around KL are generally characterised by arched ceilings, ornate carvings, and embellishments. Many are well worth a tour, but as with touring mosques, pay attention to signage concerning attire and behaviour within the temples.
Most popular with tourists are: Chen See Shu Yuen Temple (on Jalan Stadium) with its exquisite glazed ceramic carvings and sculptures; Then Hou Temple atop Robson Hill (off Jaln Syed Putra).
Hindu
Hindu temples are also found throughout KL and Malaysia, and are generally characterised by an open design and extremely intricate statues and bright colours. Tourists are most likely to see the temples at the Mid Valley Megamall and Sri Maha Mariamman temple on the edge of Chinatown, but the most stunning examples of Hinduism are found at the Batu Caves just north of the city.
Christianity
There are also numerous Christian churches in KL and Malaysia, several with unique stories that are interesting to history buffs (and most will surely welcome Christian tourists). The most photogenic churches in KL include the small, unpretentious St Mary's Cathedral on Jalan Raja (consecrated in 1893) and St. Andrew's Presbyterian Church (built in 1918, and home to the International Church of KL).
Unlike elsewhere in the world, the followers of these various faiths share KL quite harmoniously, and are most often respectful of others' beliefs. At times of festivals and feasts, this pleasant mix is especially prevalent. Enjoy!
