The Ghadīr Khumm was a gathering of Muslims to attend a sermon delivered by the Islamic prophet Muhammad on 16 March 632 CE. The gathering is said to have taken place by the ghadir in the wadi of Khumm, located near the then settlement of al-Juhfa on the path between Mecca and Medina, where Muhammad halted the large caravan of Muslims who had accompanied him in the Farewell Pilgrimage, his only Hajj ritual.
