AD 632

Ghadir Khumm

Muhammad's declaration concerning Ali at Ghadir Khumm

A single Arabic word spoken at a watering hole on the road home from Mecca — mawla — became the evidence for two different accounts of who should lead the Muslim community.

A halt at the watering place of Khumm

Returning toward Medina after the Farewell Pilgrimage, Muhammad stopped at the watering place of Khumm, between Mecca and Medina, and addressed the pilgrims travelling with him. The day is fixed in the Islamic calendar — 18 Dhu al-Hijjah 10 AH — but the Common Era conversions disagree, putting it on 16, 17 or 18 March 632.

One transmitted version has him urge his listeners to hold fast to the Book of God and remind them of their obligations toward his household. Another widely transmitted report preserves the declaration: "For whomever I am his mawla, then Ali is his mawla."

The setting was not a mosque or a palace but a stop on the road, and the account reaches us through companions such as Zayd ibn Arqam rather than through a written record made that day.

Two sermons, two dates, one label

"Final sermon" is a label that collapses distinct addresses. The Farewell Sermon proper was delivered earlier, at Arafat during the pilgrimage; Ghadir Khumm came later, on the return journey, on 18 Dhu al-Hijjah 10 AH.

Converting 18 Dhu al-Hijjah into a Common Era day depends on lunar-calendar reconstruction and on whether one uses the Julian or the proleptic Gregorian convention. Encyclopaedia Iranica settles on 16 March; other modern conversions yield 17 or 18 March.

The listed "March 18" may simply be the eighteenth day of Dhu al-Hijjah read as a civil-calendar date.

What mawla was taken to mean

Mawla carries several senses — patron, master, protector, close associate — and the interpretation is the central Sunni–Shia dispute over the episode. Shia tradition reads the declaration as investing Ali with authority over the community.

Many Sunni authorities preserve the same report while declining to read it as a political appointment. The sources record a memorable public statement of Ali's standing; they do not document a transfer of government that day.

The declaration is commemorated as Eid al-Ghadir.

Traditional date. Conventionally dated here; the research places it at ~0632-03-16.

What the sources leave uncertain

The secure traditional designation is 18 Dhu al-Hijjah 10 AH. Conversions into a Common Era date differ because of lunar-calendar reconstruction and Julian-versus-proleptic-Gregorian conventions; Encyclopaedia Iranica gives 16 March 632, while other modern conversions yield 17 or 18 March.
The word mawla has several possible senses, including patron, master, protector or close associate. Whether the declaration appointed Ali as political successor is the principal Sunni–Shia interpretive dispute.
The surviving narratives are transmitted through later hadith and historical collections rather than a contemporary transcript.
