Expedition of Zayd ibn Harithah to Wadi al-Qura took place in November, 627AD, 7th month of 6AH of the Islamic calendar.[2][3]
Wadi al-Qura was an oasis, about 7 miles from Medina. Zayd ibn Harithah set out with 12 men to survey this area and to monitor the movements of enemies of Muhammad.[1]
However, the inhabitants in this area were unfriendly to Zayd. The people there attacked the Muslims, killed 9 of them, while the rest including Zaid bin Haritha managed to escape.[1]
