A freshwater spring located in the northeast of Makkah in the valley of Hunayn. It was here that the Battle of Hunayn took place between the Muslims, led by the Prophet, and the Hawazin tribe and their allies in 630 CE. Of this event, Almighty God says in the Qurʾān: And the day of Hunayn, when your great number pleased you, but it did not avail you at all [Sūrat al-Tawba: verse 25]. 

The order to establish this spring was given by Zubaida bint Jaʿfar, the wife of the Abbasid Caliph Harun al-Rashid, in the 7th century CE. It was created to provide water for pilgrims, due to the scarcity of water in Makkah at that time. One of its most significant features is the Bridge of Hunayn, which was built in a distinctive architectural style and empties into a pool on the other side of the valley.
