Islam in Indonesia in the context of "Islam in Southeast Asia"

Cultural Muslims, also known as nominal Muslims, non-practicing Muslims or non-observing Muslims, are people who identify as Muslim but are not religious. They may variously be non-observing, secular, irreligious, or individuals who still identify with Islam due to belief, sprituality, family backgrounds, personal experiences, ethnic and national heritage, or the social and cultural environment in which they grew up.

Cultural Muslims can be found across the world, but especially in the Balkans, Central Asia, Europe, the Maghreb, various countries in South Asia and West Asia, Russia, Turkey, Singapore, Malaysia, Indonesia and the United States. In several countries and regions, self-reported Muslims practice the religion at low levels, and for some, their "Muslim" identity is associated with cultural or ethnic or national heritage, rather than merely religious faith.

Non-denominational Muslim (Arabic: مسلمون بلا طائفة) is a Muslim who does not belong to, does not self-identify with, or cannot be readily classified under one of the identifiable Islamic schools and branches. Such Muslims do not think of themselves as belonging to a denomination but rather as "just Muslims" or "non-denominational Muslims." Muslims who do not adhere to a sect are also known as non-sectarian Muslims.

While the majority of the population in the Middle East identify as either Sunni or Shi'a, a significant number of Muslims identify as non-denominational. According to a 2012 study by the Pew Research Center, Muslims who do not identify with a sect and identify as "just a Muslim" make up a majority of the Muslims in these countries: Kazakhstan (74%), Albania (65%), Kyrgyzstan (64%), Kosovo (58%), Indonesia (56%), Mali (55%), Bosnia and Herzegovina (54%), Uzbekistan (54%), and a plurality in four countries: Azerbaijan (45%), Russia (45%), Nigeria (42%), and Cameroon (40%). They are found primarily in Central Asia. Southeastern Europe also has a large number of Muslims who do not identify with a sect. Identification as "just a Muslim" is less prevalent in North Africa (median of 12%) and South Asia (median of 4%). In Lithuania, non-denominational Muslims fall into the category of "non-traditional religious communities", and are formally separated by law from Sunnis.

Halmahera, formerly known as Jilolo, Gilolo, or Jailolo, is the largest island in the Maluku Islands. It is part of the North Maluku province of Indonesia, and Sofifi, the capital of the province, is located on the west coast of the island.

Halmahera has a land area of 17,780 km (6,860 sq mi). It is the largest island of Indonesia outside the five main islands. It had a population of 162,728 in 1995; by 2010, it had increased to 449,938 for the island itself (excluding the tip which is considered part of the Joronga Islands, but including Gebe and Ju islands) and 667,161 for the island group (including all of South Halmahera and Tidore, but not Ternate). Approximately half of the island's inhabitants are Muslim and half are Christian.

Islam in Asia began in the 7th century during the lifetime of Muhammad. In 2020, the total number of Muslims in Asia was about 1.3 billion, making it the largest religion in Asia. Asia constitutes in absolute terms the world's largest Muslim population, and about 62% of the world's Muslims live in Asia, with Indonesia, Pakistan, India, Bangladesh and Malaysia having the largest Muslim populations in the world. Asia is home to the largest Muslim population, with West Asia, Central Asia, South Asia, and Southeast Asia being particularly important regions. A number of adherents of Islam have lived in Asia especially in West Asia and South Asia since the beginning of Islamic history.

The culture of Indonesia (Indonesian: Budaya Indonesia) has been shaped by the interplay of indigenous customs and diverse foreign influences. As the world's largest archipelagic country, it is home to over 600 ethnic groups, including Austronesian and Melanesian cultures, contributing to its rich traditions, languages, and customs. Indonesia is a melting pot of diversity. Positioned along ancient trade routes between the Far East, South Asia, and the Middle East, the country has absorbed cultural practices influenced by Hinduism, Buddhism, Confucianism, Islam, and Christianity. These influences have created a complex cultural tapestry that often differs from the original indigenous cultures.

Examples of the fusion of Islam with Hinduism include Javanese Abangan belief. Balinese dances have stories about ancient Buddhist and Hindu kingdoms, while Islamic art forms and architecture are present in Sumatra, especially in the Minangkabau and Aceh regions. Traditional art, music and sport are combined in a martial art form called Pencak Silat.

Arab Indonesians (Indonesian: Orang Arab Indonesia; Arabic: عربٌ إندونيسيون), or colloquially known as Jama'ah, are Indonesians of mixed Arab, mainly Hadharem from Yemen, and Indonesian descent. The ethnic group generally also includes those of Arab descent from other Middle Eastern Arabic speaking nations. Restricted under Dutch East Indies law until 1919, the community elites later gained economic power through real estate investment and trading. Currently found mainly in Java, especially West Java and East Java, they are almost all Muslims.

The official number of Arab and part-Arab descent in Indonesia was recorded since 19th century. The census of 1870 recorded a total of 12,412 Arab Indonesians (7,495 living in Java and Madura and the rest in other islands). By 1900, the total number of Arabs citizens increased to 27,399, then 44,902 by 1920, and 71,335 by 1930.

The history of the arrival of Islam in Indonesia is somewhat unclear. One theory states that Islam arrived directly from Arabia as early as the 9th century, during the time of the Umayyad and Abbasid caliphates. Another theory credits Sufi travelers for bringing Islam in the 12th or 13th century, either from Gujarat in India or from Persia. Before the archipelago's conversion to Islam, the predominant religions in Indonesia were Hinduism (particularly its Shaivism tradition) and Buddhism.

The islands that now constitute Indonesia have been recognized for centuries as a source of spices such as nutmeg and cloves, which were key commodities in the spice trade long before the Portuguese arrived in the Banda Islands in 1511. Due to the archipelago's strategic place as the gateway between the Muslim world and Imperial China, it became a busy international hub for merchants engaged in many forms of trade. It became a place where different peoples shared their respective cultures, including Islam.
