The Battle of Al-Khandaq, also known as the Battle of the Trench or the Battle of the Confederates, occurred in 5 Hijri (627 CE) in Medina. It was a pivotal siege where the Muslim community, led by Prophet Muhammad (PBUH), defended the city against a large coalition army formed by the Quraysh and allied tribes intent on eradicating Islam. The Muslims strategically dug a trench around Medina’s vulnerable northern side, a novel defensive measure suggested by Salman al-Farsi, which blocked the invaders’ cavalry and prevented direct storming of the city. Despite being heavily outnumbered—with about 3,000 Muslims facing 10,000 enemy soldiers—the Muslims endured a siege lasting about a month, ultimately forcing the enemy coalition to withdraw. The battle was a crucial Muslim victory that shifted power dynamics in the Arabian Peninsula and secured the survival of the Muslim community in Medina.
Background and Cause of the Battle
The battle was mainly instigated by the Banu Nadir, a Jewish tribe previously expelled from Medina for disloyalty to the Muslims. They went to Khaybar and conspired with the Quraysh, led by Abu Sufyan, to form a confederate army. The Quraysh, a prominent merchant tribe from Mecca, united with many Arab tribes, including Banu Ghatafan, Banu Sulaym, and Banu Asad, summoning a force between 7,500 and 10,000 men to attack Medina. The goal was to eliminate the Muslim threat and restore the Quraysh’s dominance. Although the Banu Qurayza tribe initially promised neutrality, they later violated their pact by siding with the confederates, thereby adding internal danger to the Muslim defense.
The battle of Al-Khandaq
Facing overwhelming odds, Prophet Muhammad consulted his companions on defense options. Salman al-Farsi, a Persian companion familiar with Persian military tactics, proposed digging a trench around Medina’s northern side. This had never been done in Arabian warfare before and served as a formidable barrier against the cavalry-centric forces of the enemy. The trench was approximately 5.5 kilometers long, 9 meters wide, and 4.5 meters deep, constructed over six days with the Prophet personally participating in the work.
Key Events of the Siege
When the confederate forces arrived, they were surprised to find the trench blocking their path, preventing a direct cavalry assault. The siege lasted around 30 days with repeated unsuccessful attempts by the enemy to cross the trench. The Muslims maintained strong patrols and defensive positions despite being heavily outnumbered. A famous event during the siege was when the enemy warrior Amr ibn Abd Wudd crossed the trench to challenge the Muslims to single combat. Ali ibn Abi Talib volunteered and killed him, boosting Muslim morale significantly.
The Role of Banu Qurayza and the Battle’s End
The Banu Qurayza tribe’s betrayal escalated the crisis, but the Muslims held steadfast. Eventually, worsening weather conditions, scarcity of supplies, and internal discord among confederate forces led to the withdrawal of the enemy coalition. The Muslims emerged victorious with minimal casualties—six martyrs—against higher losses for the confederates. Post-battle, the Muslims laid siege to Banu Qurayza, resulting in their surrender, with the men executed and women and children enslaved according to the customs of that time.
