Muhammad’s Violence: A Complete Accounting
Battles, Raids, Assassinations, and Massacres from Islam’s Own Sources
① THE ARGUMENT: WHAT IT IS AND WHY IT MATTERS
Muhammad lived in Mecca for approximately thirteen years after his first revelation (610–622 AD). During this period, he engaged in no military activity. He preached, he was persecuted, he endured, and he emigrated. In the ten years following the Hijra to Medina (622–632 AD), Islamic sources record that Muhammad personally participated in or directed approximately 86 military expeditions (ghazwat and saraya). He ordered targeted assassinations. He oversaw mass executions. He conducted offensive raids on caravans and settlements that had not attacked him. He died as the ruler of most of the Arabian Peninsula, his authority established overwhelmingly by military force.
This article does what no single previous article in this series has done: it catalogues the violence comprehensively, drawn entirely from Islamic sources, and classifies each incident as offensive or defensive. The purpose is not to sensationalise but to create a factual record that allows an honest evaluation of the moral-exemplar claim. If Muhammad is the perfect moral example for all time (Surah 33:21), his complete military record must be defensible—not just the battles Muslims typically discuss, but all of it.
THE NUMBERS AT A GLANCE
~86 military expeditions in 10 years
(29 battles Muhammad personally attended; 57+ raids he ordered but did not attend)
~10 targeted assassinations ordered
~1,000–1,500 killed in mass executions and tribal punishments
Estimated total killed under Muhammad’s direct authority:
3,000–10,000+ (sources vary; conservative-to-moderate range)
Offensive operations outnumber clearly defensive ones by approximately 3 to 1.
Why it matters: The question is not whether violence is ever justified. The question is whether a man who personally participated in this volume of warfare, ordered assassinations of poets and critics, oversaw the mass beheading of a surrendered tribe, and conducted offensive raids against people who had not attacked him can credibly be held up as the highest moral example for all of humanity for all of history. Christianity’s founder was executed by the state. Islam’s founder became the state.
② THE ISLAMIC DEFENSE
Muhammad fought only in self-defense and when divinely commanded. Muslim scholars emphasise that Muhammad was persecuted in Mecca for thirteen years without retaliating. He fought only after being expelled from his home, having his property confiscated, and facing ongoing Quraysh aggression. Surah 22:39–40 grants permission to fight: “Permission has been given to those who are being fought, because they were wronged.” Every military action was either defensive or pre-emptive against documented threats.
The caravan raids targeted Quraysh property that had been stolen from the Muslims. When the Muslims emigrated to Medina, the Quraysh confiscated their homes and belongings in Mecca. The caravan raids were recovery operations targeting the Quraysh’s trade routes—economically pressuring the aggressors, not attacking innocents.
The Banu Qurayza judgment was pronounced by Sa’d ibn Mu’adh, not Muhammad. The tribe chose Sa’d as their arbiter. He applied the law of Deuteronomy 20:12–14. Muhammad endorsed it as God’s judgment but did not pronounce the sentence.
The assassinations targeted people who had committed treason or incited violence. Ka’b ibn al-Ashraf had gone to Mecca to incite the Quraysh against Muhammad and had composed poetry urging the murder of Muslims. Asma bint Marwan and Abu Afak were inciting their tribes to violence. These were wartime operations against combatant propagandists, not peacetime murders of innocent critics.
Muhammad’s rules of engagement were revolutionary for his era. He forbade killing women, children, the elderly, monks, and non-combatants. He prohibited destruction of crops and livestock. He mandated humane treatment of prisoners. His military ethics were far ahead of the norms of seventh-century Arabia and compare favourably with many modern armies.
The Old Testament records far more violence attributed to divine command. Joshua’s conquest of Canaan, the destruction of Jericho, the wars of David, and the herem (total destruction) commands in Deuteronomy 20 all involve violence attributed to God’s direct order. If Muhammad’s military record is disqualifying, the same standard disqualifies the God of the Old Testament.
③ THE COMPLETE RECORD: THREE CATEGORIES OF VIOLENCE
All incidents below are documented in the earliest Islamic biographical and historical sources: Ibn Ishaq’s Sirat Rasul Allah, al-Tabari’s Tarikh, al-Waqidi’s Kitab al-Maghazi, and the hadith collections. The offensive/defensive classification follows the standard applied in international humanitarian law: “defensive” means responding to an attack or imminent documented threat; “offensive” means initiating hostilities against parties who had not attacked or were not imminently threatening the Muslim community.
CATEGORY A: MAJOR BATTLES AND CAMPAIGNS
Islamic sources record that Muhammad personally participated in approximately 27–29 battles (ghazwat). The following table covers the major engagements with estimated casualties and offensive/defensive classification.
| Battle / Campaign | Date | Muhammad’s Role | Est. Killed | Off / Def |
|---|---|---|---|---|
| Nakhla Raid | 624 Jan | Ordered (sariyya) | 1 | Offensive |
| Badr | 624 Mar | Led army (313 vs ~950) | 70 Quraysh | Offensive* |
| Banu Qaynuqa Expulsion | 624 | Led siege | 0 (exiled) | Offensive |
| Uhud | 625 Mar | Led defense (700 vs 3,000) | 70 Muslims, ~37 Quraysh | Defensive |
| Banu Nadir Expulsion | 625 | Led siege | 0 (exiled) | Offensive |
| Battle of the Trench | 627 Mar | Led defense of Medina | ~10 total | Defensive |
| Banu Qurayza Massacre | 627 Apr | Endorsed/oversaw | 600–900 beheaded | Offensive† |
| Treaty of Hudaybiyyah | 628 | Negotiated | 0 | Diplomatic |
| Khaybar | 628 May | Led army (~1,600) | 93 killed | Offensive |
| Mu’tah | 629 Sep | Ordered (sariyya, 3,000) | 12 Muslims, ~unknown | Offensive |
| Conquest of Mecca | 630 Jan | Led army (~10,000) | ~24 killed | Offensive |
| Hunayn | 630 Feb | Led army (~12,000) | ~70 enemy | Defensive‡ |
| Siege of Ta’if | 630 Feb | Led siege | ~12 Muslims | Offensive |
| Tabuk | 630 Oct | Led army (~30,000) | 0 (no battle) | Offensive |
| MAJOR BATTLES SUBTOTAL | ~1,000–1,300 | ~10 Off / 3 Def |
* Badr: Classified offensive because Muslims marched out to intercept a Quraysh trade caravan; the battle occurred when the Quraysh army came to protect it. The Muslims initiated the military operation. † Banu Qurayza: Classified offensive because the tribe had surrendered; the mass execution occurred post-combat. ‡ Hunayn: Defensive in that the Hawazin/Thaqif gathered forces after the Conquest of Mecca; however, this was a response to Muhammad’s prior conquest.
CATEGORY B: TARGETED ASSASSINATIONS ORDERED BY MUHAMMAD
The following individuals were killed on Muhammad’s specific order or with his explicit approval, as documented in Ibn Ishaq, al-Tabari, al-Waqidi, and the hadith collections.
| Target | Date | Reason Given | Method | Off / Def |
|---|---|---|---|---|
| Asma bint Marwan | 624 | Poetry mocking Muhammad | Stabbed while nursing | Offensive |
| Abu Afak | 624 | Poetry criticising Muhammad | Stabbed in sleep | Offensive |
| Ka’b ibn al-Ashraf | 624 | Poems inciting Quraysh; mourned Badr dead | Lured out and stabbed | Offensive |
| Ibn Sunayna (Jewish merchant) | 624 | Muhammad said “kill any Jew you can” | Stabbed by companion | Offensive |
| Abu Rafi’ (Sallam ibn Abi al-Huqayq) | 625 | Alleged Quraysh collaboration | Assassinated at night | Offensive |
| Khalid ibn Sufyan | 625 | Alleged plot to attack Medina | Assassinated | Pre-emptive |
| Al-Nadr ibn al-Harith | 624 | POW from Badr; had mocked Muhammad | Executed as prisoner | Offensive |
| Uqba ibn Abi Mu’ayt | 624 | POW from Badr; had harassed Muhammad | Executed as prisoner | Offensive |
| Fartana and companion | 630 | Singing girls who mocked Muhammad | Ordered killed at Mecca conquest | Offensive |
| Ka’b ibn Zuhayr (pardoned) | 630 | Poet who satirised Muhammad | Sought with death warrant; pardoned after submission | N/A |
Note: Additional assassination orders are recorded in various sources (e.g., against al-Harith ibn Suwayd, Abdullah ibn Sa’d ibn Abi Sarh). The list above represents the most extensively documented cases. The total is approximately 10–15 targeted killings.
CATEGORY C: CARAVAN RAIDS AND MINOR EXPEDITIONS (SARAYA)
Ibn Ishaq and al-Waqidi record approximately 57–60 expeditions (saraya) that Muhammad ordered but did not personally attend, plus smaller ghazwat he led. Most of these were caravan raids, reconnaissance missions, or punitive expeditions against tribes. The following represents the pattern:
| Expedition Type | Approximate Count | Typical Target | Off / Def |
|---|---|---|---|
| Caravan raids (Quraysh) | ~15–20 | Meccan trade caravans | Offensive |
| Tribal punitive expeditions | ~15–20 | Tribes that resisted or betrayed treaties | Mixed |
| Reconnaissance/intelligence | ~10 | Scouting enemy positions | Pre-emptive |
| Tax/zakat collection enforcement | ~5–10 | Tribes refusing tribute | Offensive |
| Post-conquest pacification | ~5–10 | Remaining resistance in Arabia | Offensive |
Note: Casualty estimates for the saraya are poorly documented. Most involved small forces (10–200 men) and produced modest casualties. Cumulatively, they likely resulted in several hundred to over a thousand additional deaths across the ten-year Medinan period.
THE GRAND ACCOUNTING
| Category | Estimated Killed | Offensive | Defensive | Mixed/Pre-emptive |
|---|---|---|---|---|
| Major battles/campaigns | 1,000–1,300 | ~800–1,100 | ~120–170 | ~50 |
| Banu Qurayza massacre | 600–900 | 600–900 | 0 | 0 |
| Targeted assassinations | 10–15 | 10–15 | 0 | 0 |
| Caravan raids & saraya | 500–1,000+ | 300–700 | 50–100 | 150–200 |
| Tribal expulsions (Qaynuqa, Nadir) | Low (exiled) | — | — | — |
| ESTIMATED TOTAL | 2,100–3,200+ | ~1,700–2,700 | ~170–270 | ~200–250 |
Note on ranges: These are conservative estimates based on the numbers explicitly stated in the earliest sources. Some historians estimate higher totals. The Banu Qurayza massacre alone accounts for the largest single incident. The offensive-to-defensive ratio across all categories is approximately 3:1 by casualty count and approximately 4:1 by number of operations. The overwhelming majority of killing during Muhammad’s career was initiated by his forces, not in response to attack.
THE THREE DEADLIEST EVENTS
1. Banu Qurayza massacre (627): 600–900 men beheaded in one day. Women and children enslaved. Muhammad endorsed the sentence as “the judgment of Allah.” Offensive: the tribe had surrendered.
2. Battle of Khaybar (628): ~93 killed. Jewish settlement attacked without prior aggression against Medina. Muhammad married Safiyya from the captives. Offensive.
3. Battle of Badr (624): ~70 Quraysh killed. Muslims marched to intercept a trade caravan. The battle arose from the caravan raid, not from a Quraysh attack on Medina. Offensive initiation.
④ ISLAMIC DOCUMENTATION AND ARGUMENTS AGAINST THE CRITICAL CLAIMS
The Quraysh aggression justified all subsequent military operations. Thirteen years of persecution, torture, economic boycott, attempted assassination (the plot against Muhammad before the Hijra), and confiscation of property created a state of war that justified the entire Medinan military programme. The caravan raids were economic warfare against an enemy who had already declared hostilities. Surah 2:190: “Fight in the way of Allah those who fight you.”
Banu Qurayza committed treason during the Battle of the Trench. The tribe violated their treaty with Muhammad by negotiating with the besieging Quraysh confederacy. In wartime, treason is a capital offence in virtually every legal system in history. The punishment was harsh but not unprecedented.
The assassinations targeted combatants, not civilians. Ka’b ibn al-Ashraf was not merely a “poet.” He travelled to Mecca to incite the Quraysh to war, composed propaganda designed to motivate violence against Muslims, and functioned as a wartime propagandist. In modern terms, he was a combatant engaged in information warfare.
Badr was defensive because the Quraysh were the aggressors in the broader conflict. Even if the Muslims marched to intercept a caravan, the broader context was that the Quraysh had expelled the Muslims from Mecca, seized their property, and continued to threaten them. An individual operation can be tactically offensive while being strategically defensive.
Muhammad’s total casualties are modest by historical standards. The entire casualty count of Muhammad’s military career is lower than many single battles in Roman, Persian, Chinese, or medieval European warfare. Alexander the Great, Caesar, Genghis Khan, and Charlemagne all caused vastly more death. Muhammad unified Arabia with remarkably low total casualties compared to other empire-builders.
The Conquest of Mecca was nearly bloodless. Muhammad’s greatest military achievement—the conquest of his enemies’ capital with an army of 10,000—produced only about 24 deaths. He granted general amnesty. This is one of the most merciful conquests in military history.
⑤ THE PROBLEM WITH THE ISLAMIC RESPONSE
The “broader context of self-defense” cannot cover offensive operations against unrelated parties. The Quraysh conflict is real: they persecuted the Muslims and expelled them from Mecca. Military operations against the Quraysh can be contextualised within that conflict. But many of Muhammad’s military actions were not against the Quraysh. The Banu Qaynuqa, Banu Nadir, and Banu Qurayza were Jewish tribes in Medina. Khaybar was a Jewish settlement. The expedition to Tabuk targeted the Byzantine frontier. The post-conquest saraya targeted tribes across Arabia who had not been involved in the Mecca conflict. The “self-defense against the Quraysh” framework cannot account for military operations against parties who were not the Quraysh and had not attacked Medina.
The Banu Qurayza “treason” defense does not justify mass execution of surrendered prisoners. Even accepting that the Banu Qurayza violated their treaty (which is debated by some historians), the execution of 600–900 men who had surrendered—not combatants killed in battle but prisoners executed after the fighting was over—is not defensible by any standard that claims to be the highest moral example for all time. Every modern legal framework, every international humanitarian law instrument, and every ethical tradition distinguishes between killing in battle and executing prisoners. The Banu Qurayza men were not killed fighting; they were beheaded after surrendering. Muhammad did not merely permit this; he declared it the judgment of God. A perfect moral exemplar endorsing the mass beheading of surrendered prisoners is a perfect moral exemplar whose standard permits mass beheading of surrendered prisoners.
The assassination targets include people whose only offence was speech. Ka’b ibn al-Ashraf composed poetry. Abu Afak composed poetry. Asma bint Marwan composed poetry. The “combatant propagandist” reframing is a modern projection onto seventh-century events. Even if Ka’b went to Mecca to encourage war, the method of his killing—lured out of his home under false pretences of friendship and stabbed—is assassination by deception. Asma bint Marwan was reportedly stabbed while nursing a child. Abu Afak was killed in his sleep. These are not battlefield engagements against armed combatants. They are targeted killings of unarmed individuals, carried out by deception, for the offence of critical speech. A moral exemplar who orders the assassination-by-deception of poets is a moral exemplar whose standard permits the assassination-by-deception of poets.
The offensive-to-defensive ratio is the decisive evidence. When the complete record is tallied, offensive operations outnumber defensive ones by approximately 3:1 in casualties and 4:1 in operations. The caravan raids were initiated by the Muslims. Khaybar was attacked by the Muslims. The Banu Qurayza were besieged and executed by the Muslims. The Conquest of Mecca—however merciful its conclusion—was a 10,000-man invasion force marching on a city. The post-conquest expeditions were pacification campaigns against tribes who had not attacked Medina. The claim that Muhammad fought “only in self-defense” is contradicted by the quantitative evidence in Islam’s own sources. The majority of his military career was offensive.
Low total casualties do not establish moral exemplarity. Muhammad killed fewer people than Genghis Khan. This is true and irrelevant. The question is not whether Muhammad was more or less violent than history’s worst conquerors. The question is whether his conduct qualifies as the highest moral standard for all time. The moral-exemplar claim is not graded on a curve against other warlords. It is an absolute claim: this man represents the best that humanity can be. A military record that includes mass execution of prisoners, assassination of poets, offensive raids on settlements, and conquest of cities is a military record that does not meet that standard—regardless of how it compares to other military records.
The Old Testament comparison fails on the same grounds as in Article 13. The Old Testament records violence commanded by God in specific historical contexts. Christians do not claim that Joshua is the moral exemplar for all humanity for all time. They claim Jesus is. Jesus never fought a battle, never ordered an assassination, never led an army, and died at the hands of the state rather than wielding its power. The relevant comparison is not Muhammad versus Joshua. It is Muhammad versus Jesus—because both are presented by their respective traditions as the supreme model of human life. One model conquers; the other is crucified. One model kills enemies; the other says “Father, forgive them.”
THE CUMULATIVE PROBLEM
The complete accounting reveals a pattern that the “self-defense” narrative cannot contain. In ten years, Muhammad conducted approximately 86 military operations, the overwhelming majority offensive. He ordered the assassination of approximately 10–15 individuals, most for the offence of speech. He endorsed the mass beheading of 600–900 surrendered prisoners. He attacked settlements (Khaybar) that had not attacked him. He led a 10,000-man conquest of Mecca. He dispatched armies to the Byzantine frontier. He sent tax-enforcement expeditions against tribes across Arabia. The offensive operations outnumber the defensive ones by a ratio of approximately 3–4 to 1. This is the military record of a conqueror—a successful one, and in some respects a restrained one, but a conqueror nonetheless. Islam asks the world to regard this conqueror as the perfect moral example for all humanity for all time. The record, tallied in Islam’s own sources, does not support that claim.
⑥ KEYS TO ADDRESS THIS IN A CONVERSATION
1. Lead with the numbers, not the emotions. The power of this article is its accounting. Do not begin with the Banu Qurayza massacre—that immediately triggers a defensive reaction. Begin with the overall statistics: “Did you know that Islamic sources record about 86 military expeditions in ten years? That most of them were offensive, not defensive? I wasn’t expecting that when I read the sources.” Numbers are harder to dismiss than narratives.
2. Define offensive and defensive clearly. Before your Muslim friend can argue that everything was defensive, define terms: “By ‘defensive,’ I mean responding to an attack that has already happened or is imminently documented. By ‘offensive,’ I mean initiating military action against a party that hasn’t attacked you. Can we agree on those definitions?” Once agreed, walk through the major events. Badr: who marched where? Khaybar: who attacked whom? The definitions do the work.
3. Use the Banu Qurayza as the moral test case. Once the overall pattern is established, focus on the Banu Qurayza: “Six hundred to nine hundred men were beheaded after surrendering. Muhammad called it the judgment of God. Even if they broke a treaty—is the mass execution of surrendered prisoners what the perfect moral example looks like? Is that the standard you want applied to your community if you ever surrender in a conflict?”
4. Ask about the poets specifically. “Ka’b ibn al-Ashraf wrote poems criticising Muhammad. Muhammad sent men to kill him—by pretending to be his friends and luring him out of his home. Whatever Ka’b did, is assassination-by-deception the response of the perfect moral example? What does that standard mean for how we treat people who criticise us?”
5. Do not let the conversation become “Islam vs. the Old Testament.” If your friend raises Joshua or David, redirect: “Christians don’t claim Joshua is the perfect moral example for all time. We claim Jesus is. And Jesus never led an army. The comparison that matters is Muhammad versus Jesus, because those are the two figures our traditions hold up as the ultimate standard.”
6. Acknowledge what is genuinely admirable. The Conquest of Mecca was remarkably restrained. Muhammad’s rules of engagement were ahead of their time. His treatment of some prisoners was generous. Say so. Acknowledging the genuinely positive elements of the record makes you credible when you point to the genuinely troubling ones.
7. End with the contrast one last time. “When Jesus was arrested, Peter drew a sword to defend him. Jesus said, ‘Put your sword back in its place’ (Matthew 26:52). Then he healed the man Peter had wounded. When Jesus was on the cross, he said, ‘Father, forgive them, for they do not know what they are doing’ (Luke 23:34). That is one model of the perfect life. Muhammad’s model is different. Which one looks more like what God would do if He became a man?” Let the question sit.
