17.2 Greater and Lesser Jihad
In Islam, jihad (which means “struggle”) is often described in terms of two broad categories:
- Greater Jihad
- Lesser Jihad
These categories help distinguish between different types of struggle.
The distinction between “greater” and “lesser” jihad is commonly associated with a Hadith in which the Prophet Muhammad speaks to soldiers returning from battle. Some scholars classify this specific Hadith as da‘if (weak), which is why some modern movements prioritize the military definition of jihad.
Even so, the broader idea that jihad includes both internal and external struggle is widely recognized.

Greater Jihad (Internal Struggle)
The greater jihad refers to the internal struggle within a person.
This includes things such as:
- Resisting sinful behavior
- Controlling anger, pride, and selfish desires
- Remaining faithful during hardship
- Developing discipline, patience, and integrity
This form of jihad focuses on improving moral character. It is ongoing and applies to daily life.
The Qur’an clearly supports internal striving, even though it does not use the term “greater jihad.” For example, Qur’an 91:7–10 discusses the purification of the soul versus its corruption. This is comparable to the Christian idea of putting on the “armor of God,” as described in Ephesians 6:10–17.
Many Muslims understand this internal struggle to be the most important form of jihad, which is why it is called the greater jihad.

Lesser Jihad (External Struggle)
The lesser jihad refers to external forms of struggle, which can include social, political, and military action.
Examples may include:
- Standing up against injustice
- Defending a community
- Participating in military conflict under certain conditions
In Judaism, lesser jihad is most comparable to ancient Israelite wars fought under God’s command, sometimes referred to as milhemet mitzvah (commanded war).
After the New Testament period, Christians also developed ideas such as Just War Theory (associated with Augustine of Hippo and Thomas Aquinas) and the Crusades, which allowed for religiously justified warfare. However, there is no direct equivalent to lesser jihad in core New Testament teaching.
Jus ad bellum (the right to go to war) in Islam often requires a caliph or legitimate state authority to declare it.
Thus, jihad ≠ vigilante actions.
Additionally, traditional Sharia (Islamic law) prohibits killing non-combatants, including women and children, and forbids unnecessary destruction of property or trees during lesser jihad. These rules function as moral guardrails, similar in some ways to Christian Just War Theory.

Jihad can be understood as a spectrum of struggle, ranging from:
Personal, internal effort → Outward action in society → Armed conflict under certain conditions
Different individuals, communities, and scholars emphasize different parts of this spectrum.
Understanding these categories is important because, throughout history, different groups have interpreted and applied jihad in different ways. We will continue exploring these interpretations in upcoming sections.
Next, in section 17.3, we will examine the historical context and some varieties of jihad.
