By the Sword and the Shade of Spears: A Critical Review of Military Doctrines in Early Islamic History

1. Mass Execution of Prisoners (The Incident of Banu Qurayza)

Warfare in early Islamic history was not limited to open combat in battlefield scenarios. In certain instances, it extended to mass executions following the complete surrender of an opponent.

The Event: The handling of the Banu Qurayza tribe (5 AH / 627 CE) stands as the most prominent example. After the tribe surrendered and agreed to submit to arbitration, a verdict was issued to execute all adult men and post-pubescent youths. Their necks were struck in trenches dug specifically for this purpose in the marketplace, while the women and children were taken as captives and spoils of war.

The Authentic Historical Evidence: Ibn Ishaq narrates in Sirat Ibn Hisham (the foundational text of prophetic biography):

"Then they surrendered, and the Messenger of Allah (PBUH) confined them... Then the Messenger of Allah (PBUH) went out to the marketplace of Medina and dug trenches in it. He then sent for them and struck their necks in those trenches."

2. "Al-Bayat" and the Incidental Killing of Civilians (Night Raids)

In modern warfare, international humanitarian law strictly criminalizes indiscriminate attacks that fail to distinguish between combatants and civilians. However, early medieval military doctrines permitted tactics that inherently resulted in civilian casualties as an accepted byproduct of military operations.

The Event: The practice of "Al-Bayat"—launching surprise night raids on enemy settlements while they slept—was permissible. Due to the darkness, these attacks inevitably led to the wounding or killing of women and children.

The Highest Grade of Authentic Evidence: As recorded in the foundational Hadith texts by the companion As-Sa'b bin Jathama:

"The Prophet (PBUH) was asked about the civilian families (women and children) of the polytheists, whether they could be attacked at night (Al-Bayat) given that some of their women and children might be hit. He replied: 'They are from among them.'" (Narrated by Al-Bukhari and Muslim).

This prophetic decree ("They are from among them") lifted the prohibition on killing women and children if it occurred incidentally during surprise night raids.

3. Targeted Assassinations of Dissidents

The political system established in Medina maintained zero tolerance for public dissent, ideological subversion, or satirical critique. Targeted assassination was utilized as a tool to neutralize prominent figures who publicly opposed or satirized the leadership.

The Event: The targeted eliminations of figures such as the poet Ka'b bin al-Ashraf and the Jewish leader Abu Rafi' bin Abi al-Huqayq were carried out via nocturnal stratagem and deception.

The Evidence from Sahih Al-Bukhari: Regarding the assassination of Ka'b bin al-Ashraf, Jabir bin Abdullah narrated that the Prophet said:

"Who is ready to kill Ka'b bin al-Ashraf, for he has harmed Allah and His Messenger?" Muhammad bin Maslama stood up and said, "O Messenger of Allah! Do you like me to kill him?" He said, "Yes." (Narrated by Al-Bukhari).

The operatives were explicitly granted permission to use verbal deception to lower the target's guard before executing him at night.

4. Economic Warfare and Environmental Destruction (Burning of Orchards)

Despite general prohibitions against unnecessary destruction, actual military implementation included the tactical destruction of local ecosystems and agricultural assets to force the capitulation and forced displacement of opponents.

The Event: During the siege of the Banu al-Nadir tribe, an order was executed to cut down and burn their vital palm orchards (known as Al-Buwayrah) to break their economic resilience and compel them into forced exile.

The Definitive Qur'an and Hadith Evidence: The Qur'an documents this event, granting it religious legitimacy in Surah Al-Hashr:

"Whatever palm trees you cut down or left standing on their roots, it was by permission of Allah and so that He might disgrace the defiantly disobedient." (Surah Al-Hashr - Verse 5).

This is further solidified by Imam Al-Bukhari in his Sahih from Ibn Umar: "The Messenger of Allah (PBUH) burned the palm trees of Banu al-Nadir and cut them down." (Sahih Al-Bukhari).

Critical and Philosophical Analysis

When assessing these historical events through the lens of modern humanitarian and philosophical standards, it becomes evident that the military apparatus of early Islamic history operated fully within the brutal geopolitical realities of the medieval world. The institutionalization of practices like mass prisoner executions, targeted assassinations of political dissidents, and the acceptance of collateral civilian casualties during night raids challenges idealized narratives. Instead, it contextualizes these campaigns for what they historically were: wars of expansion, state-building, and absolute subjugation, utilizing the exact same harsh instruments of power as any other military empire in human history.
