Wetu Telu ("three times") is the traditional religion of the Sasak people of Lombok, Indonesia. Now the religion is centered around Bayan, a town north of Lombok, although it used to be widespread all over Lombok. It is a syncretic form of Islam which incorporates both Hindu and indigenous animist beliefs. Followers of Wetu Telu do not pray five times a day and some observe just three days of fasting during Ramadan.
Wetu Telu means "three times". Wetu Telu is often compared with Waktu Lima or Wetu Lima ("five times"), another more orthodox sect of Islam in Lombok which is known for its strong attempts to eliminate Wetu Telu.
Before the arrival of foreign influence, the people of Lombok practiced a form of animism known as Boda, focusing especially on the worship of the spirits of the ancestors. Sasak followers of Boda are known as Sasak Boda Despite the name, there is no relationship between Boda and Buddhism.
In the 7th century, Hindu-Buddhism began to influence the island through the influence of the Majapahit Empire. After the decline of Majapahit, Islam was introduced to Lombok by the Javanese in the 13th century through the northwest part of the island. This Javanese Islam intermingles with Javanese Sufism and is full of mysticism. In the 16th century the people of Makassar arrived in eastern Lombok and managed to capture Selaparang, an original kingdom of Sasak. Compared with the Javanese people, the Makassarese were more successful in introducing Sunni Islam to the island. Despite the complete conversion of Sasak people to Islam, this version of Islam, known as Wetu Telu, was highly syncretic, mixing animist and Hindu-Buddhist elements with Islam.
Local Wetu Telu followers rely on an old palm leaf manuscript (lontar) to explain how Islam came to be accepted on Lombok and how it became differentiated from Waktu Lima:
Pangeran Sangopati brought Islam to Lombok. His oldest son founded the Wetu Lima, while his younger son founded the Wetu Telu. The followers of the oldest son, however, were stuck by all kinds of accidents, disease and famine. The younger son's followers prospered. So it was decided to lock the Wetu Lima teachings in an iron chest which was thrown into the sea. Everyone was then blessed by Allah, and prospered thereafter.
