Exploring Islamic Sects: A Guide to Beliefs, Practices, and Diversity

Introduction

This writing explores a topic titled “Sects in Islam.” The objective is to delve into the development and emergence of sects and belief systems within religion, particularly Islam. This phenomenon often begins with movements that aim to reconstruct, purify, or innovate upon traditional religious teachings. However, such efforts may lead to the formation of groups whose ideologies diverge significantly from the original faith—sometimes to the extent that they evolve into entirely new religions.

This article offers a concise introduction to the concept of belief and religion, followed by an exploration of how sects emerge and evolve within religious communities.

Faith and Religion: A Natural Human Instinct

Why do humans turn to religion? Many believe religion is a natural human need. Humans, being inherently vulnerable to life’s challenges, often seek strength from an external source. This need gives rise to belief—faith in something greater—which later forms the foundation of religion.

Before embracing a religion, a person must first believe in its teachings. Religion, at its core, involves faith in the sacred (the numinous). Rudolf Otto, in his work The Idea of the Holy (1917), argues that the numinous feeling precedes any rational or ethical religious commitment. It is this emotional and spiritual response to the mysterious and powerful that underpins religious belief¹.

As belief strengthens, it manifests through worship, rituals, religious leaders, sacred texts, and structured doctrines. Eventually, belief becomes institutionalized—forming what we understand today as religion.

Islamic scholar Ibn Hajar supports this by stating that belief gives birth to religion—not the other way around. Prophets first believed in the revelations they received; only then did they preach them, forming the religions we know today.

Over time, religion expands into multiple dimensions, influencing culture, ethics, and science. This expansion gives rise to fields like the sociology of religion, anthropology of belief, and philosophy of religion.

Religion has shaped human civilization. As Maulana Muhammad once said, religion is the driving force behind the moral and intellectual development of humanity—from Abraham and Moses to Buddha and Muhammad².

The Birth of Sects and Belief Movements

Despite its noble goals, religion sometimes fractures. Discontent, reinterpretation, or dissatisfaction with mainstream teachings can lead to sects—subgroups within a religion that hold distinct beliefs. These sects can sometimes become new religions altogether.

Sects emerge from individuals or groups who seek alternative expressions of faith. According to Soemarno W.S., religious sects can be classified into:

1. Individual belief groups – small personal systems of faith without outreach,
2. Religious groups – organized efforts to spread alternative teachings,
3. Shamanistic groups – blending traditional healing with spiritual elements³.

The word “sect” originates from Latin secta, meaning “a group that follows.” It usually refers to philosophical, religious, or political groups that diverge from the mainstream. Sects often emphasize certain doctrines while rejecting others.

Historically, all major religions have seen the emergence of sects. For instance, the Islamic sect Hashshashin (1090–1275 CE), a radical branch of the Ismaili Shiites led by Hasan-i Sabbah, practiced political assassinations and secret rituals. Christianity, Judaism, Hinduism, and Buddhism all have sectarian histories.

From a sociological perspective, sects and belief movements are religious expressions—small or large—that deviate from the dominant religious culture. For outsiders, these deviations may seem negative, but for adherents, they are often seen as purer or more spiritually fulfilling interpretations of faith.

Sect vs. Belief Movement: A Sociological Debate

Sociologists often use the term “sect” broadly, even for movements traditionally labeled heretical. While the term may carry a negative connotation, 20th-century scholars like Max Weber and Ernst Troeltsch analyzed sects as important contributors to democratic values and individualism—especially among Protestant groups⁴.

Unlike sects, belief movements are often more flexible, seeking to meet emotional and communal needs rather than offering grand theological systems. However, in the 1970s, the rise of "New Religious Movements" complicated this distinction. These groups often faced accusations of manipulation, brainwashing, or extremist practices.

Modern sect studies began with Weber and Troeltsch, who explored how religious groups influenced Western society. Later scholars, like Jessica Stern, investigated the psychological profiles of extremist sect leaders and their followers. In her book Terror in the Name of God (2003), Stern reveals how sect leaders exploit ambivalent, disillusioned individuals—often well-educated but socially isolated⁵.

These followers are often drawn to sects because of:

• Emotional engagement in worship,
• Close-knit community bonds,
• Opportunities for participation and leadership,
• A sense of purpose and identity.

Dangers and Dynamics of Radical Sects

While some sects are harmless, others have darker sides. Certain sect leaders manipulate followers by claiming exclusive knowledge or divine status. They may demand total obedience, wealth, or even sexual submission.

Some infamous examples include:

• People’s Temple: Over 900 people committed suicide in Jonestown, Guyana (1978).
• Branch Davidians: 78 died in a standoff with the FBI in Waco, Texas (1993).
• Order of the Solar Temple: 50 members died in a mass suicide in Switzerland (1993).

These sects often isolate members physically and emotionally. Leaders heighten fear—preaching apocalyptic doom while offering “salvation” only through obedience to the sect. Dissent is punished, and exclusivity is enforced by relocating members to remote compounds.

In 1985, the U.S. government raided a Christian sect called the CSA (Covenant, the Sword, and the Arm of the Lord) in Arkansas. This group had fortified their compound, anticipating attacks from outsiders, and stockpiled food and weapons for years.

Shoko Asahara, the leader of the Japanese Aum Shinrikyo sect, created a hybrid doctrine combining elements of Buddhism, Hinduism, and Christianity. He proclaimed himself a messianic figure, justified abuse, and orchestrated the 1995 Tokyo subway sarin gas attack.

In Indonesia, sects are also common. Examples include:

• Lia Aminuddin’s Eden Sect,
• Mangapin Sibuea’s Doomsday Sect,
• The Madi Sect in Sulawesi,
• Parmalim in North Sumatra.

As of 1965, there were over 300 sects in Indonesia. Many more have emerged since.

Criminologist Mustofa (University of Indonesia) argues that sects often arise from dissatisfaction with religious institutions. When doctrine becomes rigid or irrelevant, people search for more personal and fulfilling expressions of faith. In an increasingly individualistic world, alternative spiritual paths become more appealing⁶.

Conclusion

Religion is meant to guide humanity toward truth, morality, and salvation. Yet, when interpreted differently, it can give birth to diverse sects and belief systems. While some sects serve meaningful spiritual needs, others descend into manipulation, isolation, or violence.

Still, the study of sects offers valuable insight into human behavior, belief systems, and the dynamics of religious evolution. For scholars and researchers, this topic remains essential for understanding both historical developments and modern social transformations.
