The event of Ghadir Khumm (Arabic: حَدِيْث ٱلْغَدِيْر, romanized: Ḥadīth Al-Ghadīr; Persian: رویداد غدیر خم) refers to a sermon delivered by the Islamic prophet Muhammad S.A.W.W. at the Pond of Khumm (Arabic: غَدِيْر خُمّ, romanized: Ghadīr Khumm), shortly before his death in 632 CE.
The event of Ghadir Khumm occurred while the Muslims were returning from the Farewell Pilgrimage. A verse of the Quran was revealed instructing Muhammad S.A.W.W to deliver an important message. The Muslims were gathered and Muhammad S.A.W.W delivered a lengthy sermon. The speech included the famous statement by Muhammad that “Anyone who has me as his mawla, has Ali as his mawla“. It also state that the last verse of the Quran, which is the third verse of Al-Ma’idah (the fifth chapter of the Quran), was then revealed: “This day I have perfected your Religion for you: Completed My favour upon you, and have chosen for you Islam as your Religion.”
