Islamic terrorism

==== Jihad and Islamic jurisprudence ====
{{Main|Jihad}}

[[Islamic military jurisprudence|Techniques of war]] are restricted by classical Islamic jurisprudence, but its scope is not. [[Bernard Lewis]] states that ultimately Jihad ends when  the entire world is brought under Islamic rule and law.<ref>Lewis, Bernard, ''The Middle East: A Brief History of the Last 2000 Years'', pp. 233–34</ref> [[Fiqh#Diagram of early scholars|Classical Islamic jurisprudence]] imposes, without limit of time or space, the duty to subjugate non-Muslims, (according to Lewis).<ref>Lewis, Bernard, ''The Political Language of Islam'', p. 73</ref> [[Wael Hallaq]] writes that some radical Islamists go beyond the classical theory to insist that the purpose of jihad is to overthrow regimes oppressing Muslims and bring non-Muslims to convert to Islam. In contrast, [[Islamic modernism|Islamic modernists]]–who Islamists despise–view jihad as defensive and compatible with modern standards of warfare.<ref>{{cite book|url=https://books.google.com/books?id=IbOtAQAAQBAJ&pg=PA338|title=Sharī'a: Theory, Practice, Transformations|publisher=Cambridge University Press|year=2009|pages=338–39|author=Wael B.

;Al-Qaeda
While Islamic opponents of attacks on civilians have quoted numerous prophetic hadith and hadith by Muhammad's first successor [[Abu Bakr]],<ref name="Wiktorowicz-2003-86">{{cite journal |last1=Wiktorowicz |first1=Quintan |last2=Kaltner |first2=John |title=Killing in the Name of Islam: Al-Qaeda's Justification for September 11 |journal=Middle East Policy |date=Summer 2003 |volume=X |issue=2 |pages=86|url=https://www.aclu.org/files/fbimappingfoia/20111110/ACLURM001177.pdf |access-date=12 August 2019}}</ref> Al-Qaeda believes its attacks are religiously justified.
After its first attack on a US target that killed civilians instead (a [[1992 Yemen hotel bombings|1992 bombing of a hotel in Aden Yemen]]), Al Qaeda justified the killing of civilian bystanders through an interpretation (by one Abu Hajer) based on medieval jurist [[Ibn Taymiyyah]] (see above).

In a post-9/11 work, "A Statement from Qaidat al-Jihad Regarding the Mandates of the Heroes and the Legality of the Operations in New York and Washington", Al-Qaeda provided a more systematic justification—one that provided "ample theological justification for killing civilians in almost any imaginable situation."<ref name="Wiktorowicz-2003" />  Among these justifications are that America is leading the countries of the West in waging war on Islam, which (al-Qaeda alleges) targets "Muslim women, children and elderly". This means any attacks on America are a defense of Islam, and any treaties and agreements between Muslim majority states and Western countries that would be violated by attacks are null and void. Other justifications for killing and situations where killings is allowed based on precedents in early Islamic history include:  killing non-combatants  when it is too difficult to distinguish between them and combatants when attacking an enemy "stronghold" (''hist''), and/or non-combatants remain in enemy territory; killing those who assist the enemy "in deed, word, mind", this includes civilians since they can vote in elections that bring enemies of Islam to power; necessity of killing in the war to protect Islam and Muslims; when the prophet was asked whether Muslim fighters could use the catapult against the village of Taif, even though the enemy fighters were mixed with a  civilian population, he indicated in the affirmative; killing women, children and other protected groups is allowed when they serve as human shields for the enemy; killing of civilians is permitted if the enemy has broken a treaty.
<ref name="Wiktorowicz-2003" />

Supporters of bin Laden have pointed to reports according to which the Islamic prophet Muhammad attacked towns at night or with catapults, and argued that he must have condoned incidental harm to noncombatants, since it would have been impossible to distinguish them from combatants during such attacks.<ref>{{cite journal |last1=Wiktorowicz |first1=Quintan |last2=Kaltner |first2=John |title=Killing in the Name of Islam: Al-Qaeda's Justification for September 11 |journal=Middle East Policy |date=Summer 2003 |volume=X |issue=2 |pages=85–90 |url=https://www.aclu.org/files/fbimappingfoia/20111110/ACLURM001177.pdf |access-date=12 August 2019}}</ref><ref name="peters-cook">{{cite encyclopedia |year=2014 |title=Jihād |encyclopedia=The Oxford Encyclopedia of Islam and Politics |publisher=Oxford University Press |location=Oxford |url=http://www.oxfordreference.com/view/10.1093/acref:oiso/9780199739356.001.0001/acref-9780199739356-e-0263 |last1=Peters |first1=Rudolph |first2=David|last2=Cook |url-access=subscription |isbn=978-0-19-973935-6}}</ref> These arguments were not widely accepted by Muslims.<ref name=peters-cook />

Based on the 20th-century interpretations of [[Sayyid Qutb]], [[Abdullah Azzam]], [[Ruhollah Khomeini]], [[al-Qaeda]] and others, many if not all of those self-proclaimed jihad fighters believe that defensive global jihad is a personal obligation, which means that no caliph or Muslim head of state needs to declare it. Killing yourself in the process of killing the enemy is an act of martyrdom and it brings you a special place in [[Jannah|Heaven]], not a special place in Hell; and the killing of Muslim bystanders (nevermind Non-Muslims), should not impede acts of jihad.

{{Blockquote|Ranging from ruminations on the merits of beheading, torturing, or burning prisoners to thoughts on assassination, siege warfare, and the use of biological weapons, Muhajir's intellectual legacy is a crucial component of the [[Ideology of the Islamic State of Iraq and the Levant|literary corpus of ISIS]]—and, indeed, whatever comes after it—a way to render practically anything permissible, provided, that is, it can be spun as beneficial to the jihad. [...] According to Muhajir, [[Suicide attack#Islam|committing suicide to kill people]] is not only a theologically sound act, but a commendable one, too, something to be cherished and celebrated regardless of its outcome. [...] neither Zarqawi nor his inheritors have looked back, liberally using Muhajir's work to normalize the use of suicide tactics in the time since, such that they have become the single most important military and terrorist method—defensive or offensive—used by ISIS today. The way that Muhajir theorized it was simple—he offered up a theological fix that allows any who desire it to sidestep the Koranic injunctions against suicide.<ref name="Atlantic 2016" />}}

Clinical psychologist [[Chris Stout (psychologist)|Chris E. Stout]] also discusses the al Muhajir-inspired text in his essay, ''Terrorism, Political Violence, and Extremism'' (2017).
