1. The Pubic Hair Test:
Sunan Abi Dawud 4404 proves the execution used a crude biological filter, converting an alleged treason punishment into an indiscriminate slaughter of children.
2. Prescriptive Pattern:
Unlike Old Testament warfare—which is local, descriptive history—Muhammad's actions set an eternal, prescriptive template (Uswa Hasana) for state violence.
3. Divine Endorsement:
Muhammad elevated mass beheading directly to immutable divine law (Bukhari 3804).
Modern Islamic apologists frequently frame early Islamic warfare as purely defensive, localized operations meant to establish peace in ancient Arabia. However, the historical record preserved within the Standard Islamic Narrative (SIN) reveals a starkly different reality. The event that transpired following the Battle of the Trench—the mass execution of the bound prisoners of the Jewish Banu Qurayza tribe—stands as one of the most devastating historical and moral critiques of Muhammad’s claim to prophethood. This systematic application of state violence stands in total opposition to the character of God revealed through Jesus Christ.
The execution of the Banu Qurayza was not an active battlefield engagement, but the cold, systematic slaughter of surrendered prisoners of war over the course of a single day in the marketplace of Medina.
The Divine Endorsement of Violence:
According to Sahih al-Bukhari 3804 (cf. 4122, 3017), when the arbitrator Sa'd ibn Mu'adh decreed that every male of the tribe be slaughtered, Muhammad did not offer mercy or choose exile. Instead, he explicitly elevated this brutal verdict to immutable divine law, telling him:
"You have judged among them with the judgment of the King (Allah)."
The Biological Filter for Execution:
Rather than executing only specific tribal leaders guilty of political treason, the early Islamic state used a crude biological marker to determine which children lived or died. Sunan Abi Dawud 4404 (classified as Sahih) records the firsthand, eyewitness testimony of Atiyyah al-Qurazi, a surviving youth:
"I was among the captives of Banu Qurayza. They examined us, and those who had begun to grow pubic hair were killed, and those who had not were not killed. They uncovered my pubic hair and found it had not grown, so they put me among the captives."
Between 600 and 900 males—including young boys who had merely crossed the threshold of physical puberty—were bound, marched out to trenches dug in Medina, and systematically beheaded.
Following the mass execution, the women and children were not given humanitarian aid or released; they were legally reduced to chattel and divided among the Muslim fighters as financial assets.
The Capture of Rayhana:
According to early historical records like Ibn Ishaq’s Sirat Rasul Allah, Muhammad participated directly in the distribution of this human booty. He selected Rayhana bint Zayd, a Jewish woman whose husband and male relatives had just been slaughtered in the massacre, and claimed her as his personal war captive and concubine.
The Precedent for Permanent Law:
Under the classical rules of Sharia jurisprudence derived from this event, the reduction of non-Muslim war captives to slaves and sexual concubines (Ma malakat aymanukum) became an open-ended, legally valid mechanism of Islamic warfare.
When confronted with the horror of the Banu Qurayza massacre, Dawah practitioners almost universally attempt a tu quoque (you too) defense, pointing to the harsh warfare commands given to Joshua or Moses in the Old Testament (e.g., Deuteronomy 20). A Christian theologian must cleanly dismantle this false equivalency using covenantal theology.
The Descriptive, Completed Past vs. The Prescriptive Standard:
The geopolitical judgments recorded in the Old Testament were temporal, explicitly tied to the entry into a specific Promised Land at a specific point in salvation history, and have been completely fulfilled. Christianity does not put forward Moses, Joshua, or David as timeless, universal moral exemplars whose wartime actions are to be copied by Christians today.
Conversely, Islam puts forward Muhammad as the Uswa Hasana (the perfect, eternal pattern of conduct for all mankind, Surah 33:21), meaning a mass execution of prisoners remains an active, valid legal precedent under classical Islamic statecraft.
The True Revelation of God's Character:
Jesus Christ—who is the exact imprint of God’s nature (Hebrews 1:3)—explicitly rebuked His own disciples when they wanted to use violence to destroy a Samaritan village that rejected Him, stating:
Luke 9:55-56:
You do not know what manner of spirit you are of; for the Son of Man did not come to destroy men's lives but to save them.
While Muhammad endorsed the slaughter of hundreds of bound captives over a trench in Medina, declaring it to be the "judgment of Allah," Jesus Christ chose to heal His captors, forbid His disciples from drawing the sword, and prayed for His executioners while hanging on the Cross.
The moral fruit of a true prophet must align with the nature of the God who created life. Muhammad operated as an earthly sovereign who utilized mass execution, structural enslavement, and wartime concubinage to expand and consolidate his geopolitical power.
Conversely, Jesus Christ established a spiritual Kingdom "not of this world" (John 18:36), proving that the true revelation of the God of Israel is marked not by the shedding of the blood of one's enemies, but by the voluntary pouring out of His own blood to offer redemption to a fallen world.
