The Battle of Al-Safra in late 1811, was an early major battle in the First Campaign of the Ottoman–Wahhabi war. It occurred when Saud bin Abdulaziz's Wahhabi troops engaged Tusun Pasha's Ottoman force while it was travelling through a Wadi attempting to reach Medina. It was a resounding Ottoman defeat and they were forced to retreat.
