ﷺ

The Battle of the Trench took place in 5 Hijri. The Holy Prophet (peace and blessings be upon him) himself engaged in digging the trench with 3,000 companions, marking the boundaries with his own blessed hands and distributing ten yards of land to ten men each. The trench was dug in approximately twenty days — 300 metres in length, 9 metres in width, and 5 metres in depth.
