Islamic Jurisprudence View

In Islamic jurisprudence, jihad is understood as both:

An inner spiritual struggle (the greater jihad)
An external, defensive struggle (the lesser jihad)

When a Muslim community or territory is under attack or oppression, the defensive form of jihad becomes fard (obligatory).

Qur’anic Evidence

Islam’s guidance on jihad comes directly from the Qur’an, which permits fighting only in self-defense and to protect the oppressed:

Surah Al-Baqarah (2:190):
“Fight in the way of Allah those who fight you, but do not transgress. Indeed, Allah does not like transgressors.”
→ Combat is sanctioned only in response to aggression and must follow ethical conduct.
Surah An-Nisa (4:75):
“And what is [the matter] with you that you do not fight in the cause of Allah and [for] the oppressed among men, women, and children who say, ‘Our Lord, take us out of this city of oppressive people and appoint for us from Yourself a protector and a helper’?”
→ Encourages Muslims to rise in defense of the oppressed; a clear call to action when injustice prevails.
Surah Al-Hajj (22:39):
“Permission [to fight] has been given to those who are being fought, because they were wronged, and indeed, Allah is competent to give them victory.”
→ One of the earliest verses granting Muslims the right to defend themselves under persecution.

Authentic Hadith Narrations

The obligation of defensive jihad is further supported by authentic Hadith:

Sunan Abu Dawood (Hadith 4772):
“Whoever is killed while protecting his wealth is a martyr. Whoever is killed while protecting his family is a martyr. Whoever is killed while protecting his religion is a martyr.”
→ Emphasizes the merit of self-defense and protecting faith, life, and property.
Sunan al-Nasa’i (Hadith 4209):
“The best jihad is to speak a word of truth to a tyrant ruler.”
→ Shows that jihad includes non-violent actions like standing up for justice.

Classical Scholarly Opinions

Imam al-Nawawi

In his commentary on authentic Hadith, he stated that:

If a Muslim territory is invaded, jihad becomes fard ‘ayn (an individual obligation) for every capable person in that land.
If locals cannot defend themselves, the duty extends to neighboring areas until the threat is neutralized.

Imam Ibn Taymiyyah

He asserted:

Defensive jihad is not optional; it becomes mandatory, just like daily prayers and fasting, when Muslims are under threat.
Emphasized ethical warfare in all situations.

Imam al-Qurtubi

In his tafsir (exegesis) of Surah Al-Baqarah (2:190):

He clarified that warfare is only for self-defense.
Transgression is strictly forbidden, and defensive action must be done with restraint and justice.

Key Conditions for Obligatory Defensive Jihad

Based on Qur’anic texts and scholarly consensus, jihad becomes an individual obligation (fard ‘ayn) under these conditions:

Direct Aggression or Invasion:
Muslim land or community is attacked by non-Muslim forces or oppressive entities.
Oppression and Injustice:
Response is due to evident oppression, as mentioned in Surah An-Nisa (4:75).
Legitimate Authority and Clear Command:
Must be declared by a recognized Islamic authority to ensure ethical adherence.
Adherence to Ethical Guidelines:
Must follow Islamic moral codes, protect non-combatants, and avoid excessive destruction.

Conclusion

The concept of jihad, particularly its defensive form, is deeply rooted in:

Qur’anic instructions
Authentic Hadith traditions
Classical scholarly interpretations

When a Muslim community faces attack or severe oppression, defensive jihad becomes a collective (fard al-kifayah) or individual (fard ‘ayn) obligation. However, this duty is always balanced by strict ethical standards to ensure that:

Life, family, and faith are protected
Aggression and indiscriminate violence are avoided

Final Conclusion

In Islam, jihad is a multifaceted concept:

Spiritually: It is the inner struggle for self-purification.
Externally: It is a defensive duty under certain conditions.

The Qur’an permits fighting only in self-defense or in response to oppression, highlighted in Surah Al-Baqarah (2:190), Surah An-Nisa (4:75), and Surah Al-Hajj (22:39).

Classical scholars like Imam al-Nawawi, Ibn Taymiyyah, and Imam al-Qurtubi agree:
When Muslims are oppressed or attacked, defensive jihad becomes obligatory, but it must be carried out ethically, with justice, restraint, and protection for non-combatants.
