Muhammad's biography: the troubling events

Each event below is reported by classical Muslim sources that Sunni scholarship has historically treated as authoritative. Read each in its own voice before reading the modern apologetic.

1. Banu Qurayza

In 5/627 CE, after the Battle of the Trench, the Banu Qurayza Jewish tribe of Medina was besieged for what classical sources describe as a violation of the Constitution of Medina. After their surrender, the men were executed and the women and children enslaved. The account is preserved in Ibn Isḥāq's Sīrat Rasūl Allāh (the earliest extant biography, redacted by Ibn Hishām), in al-Ṭabarī's Tārīkh, and in canonical Sunni ḥadīth.

Bukhārī 4028 reports that Saʿd ibn Muʿādh, the ḥakam (arbiter) chosen to judge Banu Qurayza, ruled: the warriors should be killed and the women and children taken as captives, and Muhammad responded: You have judged them according to the order of the King (Allah). Ibn Isḥāq's number — 600 to 900 men executed — is contested in modern scholarship; W. N. Arafat (1976) argued the number was inflated and the event smaller; M. J. Kister (1986) defended the traditional account. Even on the conservative reading the event is severe.

2. ʿĀʾisha's age at marriage

Bukhārī 5133: The Prophet married ʿĀʾisha when she was a girl of six years and consummated the marriage when she was nine, and she remained with him for nine years. The same report is preserved as Bukhārī 5134, Bukhārī 5158, Muslim 1422a, and elsewhere with consistent wording. The reports are graded ṣaḥīḥ by classical Sunni standards.

Some modern Muslim scholars (notably the late T. O. Shanavas, and the Pakistani jurist Hakim Niaz Ahmad) have argued the chronology is incompatible with other dating in the same corpus, so that ʿĀʾisha must have been older — perhaps in her late teens. The argument has internal Islamic warrants but contradicts the most direct Sunni reports.

3. Zaynab bint Jaḥsh

Q 33:37: And when you said to him on whom Allah has bestowed favour and to whom you also have shown favour, "Keep your wife to yourself and fear Allah" — and you concealed within yourself what Allah is going to reveal, and you feared the people, while Allah is more deserving that you fear Him. So when Zayd had no longer any need for her, We married her to you, so that there would not be upon the believers any discomfort concerning the wives of their adopted sons when they no longer have need of them.

Ibn Saʿd's Ṭabaqāt and al-Ṭabarī's Tafsīr preserve the asbāb al-nuzūl (occasions of revelation) for this verse: that Muhammad saw Zaynab, the wife of his adopted son Zayd, in unguarded circumstances, and Zayd subsequently divorced her. Q 33:37 then sanctions Muhammad's marriage to her and revises the legal status of adopted-son relationships. Classical commentators (al-Ṭabarī, al-Zamakhsharī, al-Rāzī) discuss the verse with varying degrees of comfort.

4. The assassinations of Kaʿb ibn al-Ashraf and Asmāʼ bint Marwān

Kaʿb ibn al-Ashraf was a Jewish poet of Medina who composed verses ridiculing Muhammad after the Battle of Badr. Bukhārī 4037 preserves Muhammad asking Who will deal with Kaʿb ibn al-Ashraf? He has hurt Allah and His messenger. A volunteer named Muhammad ibn Maslama then arranged Kaʿb's killing. The full account, including the deception used, is in Bukhārī 4037 and parallels in Muslim, with extended narrative in Ibn Isḥāq.

Asmāʼ bint Marwān was a poetess of Medina who composed verses against Muhammad. Ibn Isḥāq preserves the report (Ibn Hishām's redaction omits her name in some manuscripts) that ʿUmayr ibn ʿAdī was sent by Muhammad and killed her in her home at night while her infant nursed at her breast. The Asmāʼ account is not preserved in canonical Sunni ḥadīth and is therefore graded by modern Muslim scholars as historically uncertain — though it is in the earliest sīra material.

Each of these has a serious modern Muslim response. The honest engager names them.

Banu Qurayza. The standard apologetic emphasises the breach of the Constitution of Medina, the practice of seventh-century warfare, the fact that Saʿd ibn Muʿādh — not Muhammad — pronounced the verdict, and W. N. Arafat's argument that the numbers were inflated. The deeper response engages classical Islamic law of war, which permitted execution of male combatants who had broken treaty terms.

The Christian engager grants the contextual point — the seventh-century setting matters — and notes two things. First, even on the most generous reading, the execution of several hundred men after their surrender is what it is. Second, the comparison being made (above all in Comparative ethics: Jesus and Muhammad) is between Muhammad and Jesus, who lived in a comparable Roman provincial setting under similar pressure. The same first-century setting that produced Muhammad's Banu Qurayza decision did not produce Jesus's Banu Qurayza decision. That is a meaningful asymmetry.

ʿĀʾisha's age. Modern Muslim apologetics have pursued two paths. The first (T. O. Shanavas and others) argues the chronological evidence in the same Sunni corpus places ʿĀʾisha in her late teens, and that the six and nine report is in tension with the dating of her sister Asmāʾ and other markers. The second concedes the traditional report and argues that seventh-century Arabian marriage practices, life expectancy, and the absence of modern adolescence-as-extended-childhood make the comparison anachronistic.

The Christian engager grants the chronological-revisionist case is internally Islamic and has real warrants. The honest counter is that even on the Shanavas reading, a man held up by Allah as the eternal uswa ḥasana (Q 33:21, the beautiful pattern) for all believers in all centuries is bounded by seventh-century Arabian norms in a way that creates difficulty for the believing Muslim woman in 2026 who reads Bukhārī 5133 plainly.

Zaynab bint Jaḥsh. The standard apologetic argues the marriage was legally innovative (revising the status of adopted-son relationships in Arab custom) rather than personally desired, and that the Qurʼānic narrative emphasises Allah's command, not Muhammad's affection. Some modern apologetics frame the occasions of revelation reports as later embellishments by hostile or unreliable narrators.

The Christian engager grants the legal-reform reading is one coherent reading. The honest counter is that the asbāb al-nuzūl reports come from classical Muslim scholarship — al-Ṭabarī, Ibn Saʿd, al-Wāḥidī — and were preserved by Sunni tradition for centuries before the modern apologetic discomfort with them.

Kaʿb ibn al-Ashraf. The classical Muslim defence is that Kaʿb's incitement constituted treason against the Medinan polity, and that Muhammad was acting as head of state, not religious leader. The modern apologetic emphasises the political nature of the act.

The Christian engager grants this is a partial defence and notes that political assassination of a poet for inflammatory verse — even granting head-of-state status — is precisely the kind of conduct that the Sermon on the Mount excludes for the Christian. The asymmetry of ethical example again returns to the foreground.

This is the page of the entire ExamineIslam library most likely to be misused. A note on how to engage it well.

Do not lead with this material. A Christian who introduces a Muslim friend to ʿĀʾisha's marriage in the first three conversations is not loving him. He is using him. Lead with relationship, with curiosity about his story, with the hope of Christ.

Do not personalise. I think Muhammad was a bad man is not a sentence a Christian needs to say. The question is not whether Muhammad was a bad man — most Muslims who have walked away from Islam still have warm feelings for him as a historical figure. The question is whether Muhammad is the uswa ḥasana, the eternal pattern for all believers. The data above raises a real question about that claim. Stay on the question.

Cite primary sources, not secondary attacks. The popular polemicists' versions of these events are often inaccurate, exaggerated, or stripped of context. Read Ibn Isḥāq and Bukhārī in their own voices. Cite the canonical numbers. Earn the right to be taken seriously by knowing the texts better than the polemicist who only knows the slogans.

Acknowledge the modern Muslim apologetic. Many serious Muslim scholars have written on these events with care. Mohammad Hashim Kamali, Jonathan Brown, T. O. Shanavas — these are not fringe voices. Engage them.

Land on Christ. The point of this page is not to humiliate. It is to clear ground for the actual Christian-Muslim conversation, which is about Jesus. The Sermon on the Mount, the cross, and the empty tomb are not weakened by Muhammad's actions in Medina. They are commended by them — by contrast.

A note for the Christian reader

Most of the Christians who handle this material best are those who have spent the most time with Muslim friends. They have learned to hold these difficulties without contempt, to mention them only when the conversation has earned them, and to keep the eyes of the conversation always on Christ. If you are early in this work, do not deploy this page in conversation. Read it, learn it, and let it inform your prayers — and let the Holy Spirit prompt the moment for any specific point in any specific conversation.
