Ghadir Khumm: the Prophet ﷺ appoints Imam Ali — the evidence and the arguments

Introduction — the day that changed the history of Islam

Between Mecca and Medina lies a place modern maps no longer mark: the pond of Khumm, at Ghadir. A dry, shadeless junction where the pilgrimage roads parted — the Egyptians turning north, the Iraqis east, the Medinans north-west. Nobody would choose to stop there, unless there were a compelling reason to. And there was one: it was the last point at which the entire caravan was still together.

On 18 Dhu al-Hijjah in the year 10 of the Hijra, that caravan came to a halt. The Prophet Muhammad ﷺ was returning from the Farewell Pilgrimage, the only pilgrimage he performed. Chroniclers put the number of pilgrims travelling with him at roughly 120,000. Those who had gone ahead were ordered back; those lagging behind were told to hurry. The ground was cleared of thorns, camel saddles were stacked into a makeshift platform, and everyone waited under the Hijazi sun until the last straggler had arrived.

What forced the halt was not a change of route. It was a verse:

"O Messenger! Convey what has been revealed to you from your Lord. If you do not, then you will not have conveyed His message. And Allah will protect you from the people." — Quran 5:67

Weigh those words carefully. The Prophet ﷺ had been preaching for twenty-three years. He had already conveyed the five prayers, the fast, the pilgrimage, alms, the law of inheritance, the prohibition of usury. And yet on that day Allah tells him that if one particular message goes unconveyed, then nothing has been conveyed. Twenty-three years of prophethood hanging on a single announcement.

Which raises the question that governs everything else: what could be important enough to halt 120,000 people under the sun of the Hijaz?

Who was Ali before Ghadir? A man impossible to overlook

Before examining what was said at Ghadir, we should understand who it was said about. The appointment of Ali ibn Abi Talib was no sudden turn of events: it was the culmination of twenty-three years in which this man had continuously occupied a place no other Companion occupied.

The first Muslim

Ali ibn Abi Talib embraced Islam at around ten years old, in the earliest days of the revelation. He is the first male to have believed in the Prophet's ﷺ message after Khadija — before Abu Bakr, before Umar, before all the Companions.

This is not a Shia claim: it is recorded by the oldest and most respected Sunni sources. Ibn Hisham reports it in his Sira, al-Tabari in his History of the Prophets and Kings, Ibn Kathir in al-Bidaya wa al-Nihaya. These authors are beyond suspicion of Shia sympathies.

Some later scholars qualified the point by saying that Abu Bakr was the first among free adult men, Khadija the first among women, and Ali the first among the young. But notice what that formulation concedes: it does not dispute Ali's chronological precedence. It acknowledges it, then creates a separate category in order to relativise it. The precedence itself stands.

Ali grew up in the Prophet's ﷺ household, raised by him, present at every stage of the revelation. No other Companion can say the same.

Laylat al-Mabit: sleeping in the Prophet's bed

In the year 1 of the Hijra, the chiefs of Quraysh met at Dar al-Nadwa and resolved to assassinate the Prophet ﷺ in his bed. To forestall the vengeance of the Banu Hashim, they decided to send one man from each clan, so that the blood would be shared among all the tribes and no retaliation would be possible.

Forewarned, the Prophet ﷺ decided to leave for Medina. But if he left an empty house behind him, the assassins would discover his escape within moments and the pursuit would begin at once. Someone had to occupy that bed.

Ali ibn Abi Talib lay down in it, wrapped in the Prophet's ﷺ green cloak, while the swords waited outside the door. This was not a calculated risk: it was near-certain death, accepted by a man in his twenties so that another might live.

The Quran itself speaks of that night:

"And among people is he who sells his soul seeking the pleasure of Allah. And Allah is full of kindness to His servants." — Quran 2:207

Sunni exegetes confirm the occasion of revelation. Al-Zamakhshari mentions it in al-Kashshaf, Fakhr al-Din al-Razi in Mafatih al-Ghayb, al-Tha'labi in his Tafsir and al-Suyuti in al-Durr al-Manthur. Here again, the source is not Shia.

The battles: Ali on every front

Badr, Uhud, Khandaq, Khaybar, Hunayn: Ali ibn Abi Talib fought in virtually every battle alongside the Prophet ﷺ, and consistently carried the heaviest burden. At Uhud, when most of the fighters scattered, he stayed. At Khandaq he faced Amr ibn Abd Wudd alone, whom no one else dared approach.

But the most telling episode is Khaybar. The fortress held out. On the first day the Prophet ﷺ entrusted the standard to an eminent Companion: the assault failed. On the second day, to another: it failed again. That evening he declared before the army:

"Tomorrow I shall give the standard to a man whom Allah and His Messenger love, and who loves Allah and His Messenger. Allah will grant victory through his hands."

All night the Companions hoped to be the one. In the morning the Prophet ﷺ asked where Ali was. He was told Ali's eyes were inflamed. He sent for him, applied his saliva to his eyelids, and handed him the standard. Khaybar fell that same day.

This hadith appears in Sahih al-Bukhari (no. 4210) and Sahih Muslim (no. 2406) — that is, in the two most rigorously authenticated collections in the Sunni world. No Muslim, of whatever school, can reject it without rejecting his own foundations.

This is the man Ghadir Khumm concerns. Not one Companion among many: the first believer, the one who offered his life, the one the Prophet ﷺ publicly declared beloved of Allah.

The sermon at Ghadir — the Prophet's ﷺ exact words

Back to the plain of Khumm. The heat was such that some folded a corner of their cloak under their feet to keep from burning on the ground. Camel saddles formed a platform. Before it the crowd sat down by tribe, as far as the eye could see.

The Prophet ﷺ began with a long sermon: he praised Allah, announced that his own death was near, and declared that he was leaving behind two weighty things to which the community must hold fast — the Book of Allah and the people of his household. Then he put a question to the assembly:

"Am I not more entitled to the believers than they are to themselves?"

The crowd answered: "Indeed, O Messenger of Allah." He then stated his own standing: "Allah is my mawla, and I am the mawla of every believer."

It was at that moment that he took the hand of Ali ibn Abi Talib and raised it high enough for all to see, and pronounced the words:

"Man kuntu mawlahu fa-Ali mawlahu."

"He of whom I am the mawla, Ali is his mawla."

Then he added this supplication:

"O Allah, befriend whoever befriends him and be the enemy of whoever is his enemy. Support whoever supports him and forsake whoever forsakes him."

The assembly then dispersed, coming forward to congratulate Ali. Among those who stepped up was Umar ibn al-Khattab, who said to him:

"Congratulations, O son of Abu Talib! You have become the mawla of every believing man and every believing woman."

It matters a great deal where these reports come from. Not one of them is a Shia source:

The hadith of Ghadir is among the best-transmitted reports in the entire Islamic tradition. Sunni scholars have catalogued its chains by the dozen: the hafiz Ibn Uqda devoted an entire work to it, and Ibn Hajar al-Asqalani and al-Dhahabi both authenticated its content. The dispute has never been about whether the event took place. It is solely about the meaning of one word.

The word "mawla" — the decisive argument

This is where everything is settled. The Arabic term mawla is indeed polysemous: depending on context it can mean friend, ally, freedman, patron, master, the one who holds authority. Scholars who reject the successional reading lean on that ambiguity and assert: "here, mawla means friend."

The objection deserves to be taken seriously. It does not survive four tests.

Point 1 — The context makes "friend" absurd.

The Prophet ﷺ had just brought 120,000 people to a standstill in open desert. He had called back those who had gone ahead, waited for those trailing behind, made tens of thousands of pilgrims exhausted by the Hajj dismount, in heat so fierce that a bare foot could not rest on the ground. One does not assemble an entire nation in such conditions to announce a friendship.

Friendship among Muslims was in any case a long-established Quranic principle: "The believing men and believing women are allies of one another" (Quran 9:71). There was nothing new to proclaim. The mismatch between the staging and the meaning being ascribed to the message is, on its own, a refutation.

Point 2 — Verse 5:67 confirms the gravity.

Allah says: "If you do not, then you will not have conveyed His message." If the content to be conveyed amounted to "Ali is a good friend, be fond of him", why would Allah threaten the total invalidation of twenty-three years of prophetic mission in the event of silence? A message whose omission nullifies the whole of prophethood cannot be a recommendation of affection. The gravity of the verse imposes the gravity of the message.

And the verse adds: "Allah will protect you from the people." An announcement of friendship exposes no one to danger. Only an announcement overturning an expected order — a designation of a successor, in a tribal society where power was negotiated between clans — could warrant such a promise of protection.

Point 3 — The Prophet ﷺ used the word of himself first.

This is the hardest argument to get around. Before speaking of Ali, the Prophet ﷺ questioned the crowd about his own standing: "Am I not more entitled to the believers than they are to themselves?" — a direct echo of verse 33:6: "The Prophet is closer to the believers than their own selves." He then stated: "Allah is my mawla, and I am the mawla of every believer."

So he uses the same word, within the same address, seconds apart, first of himself and then of Ali. Now nobody, in any school, holds that the Prophet ﷺ was asking his community "am I not your friend?" He was asserting his authority over the believers.

A basic principle of interpretation holds that a term repeated within a single statement keeps the same sense unless there is explicit indication otherwise. There is none here. If mawla means "the one holding authority" in the first occurrence, it means "the one holding authority" in the second.

Point 4 — Umar understood "successor".

Umar ibn al-Khattab was present. He was a man of political intelligence acknowledged by all, a native speaker of Arabic, an immediate contemporary of the statement. He stepped forward to Ali and congratulated him: "You have become the mawla of every believing man and every believing woman."

Consider the logic of that sentence. One does not congratulate a man on having become everyone's friend: it is not an event, and it is not acquired in an instant. One congratulates someone who has just been raised to a position. The Arabic expression used, bakhin bakhin, marks precisely that admiration before an elevation.

In other words: the first commentary on the hadith of Ghadir was delivered that very day, by an Arabic-speaking eyewitness, and that commentary was a congratulation. It depends on no school, no later scholar, no subsequent polemic.

Quran 5:3 — the message of that same day

On the day of Ghadir, another verse came down:

"Today I have perfected your religion for you, completed My favour upon you, and approved Islam as your religion." — Quran 5:3

This occasion of revelation is reported by Sunni sources, notably al-Khatib al-Baghdadi in his History of Baghdad and al-Suyuti in al-Durr al-Manthur.

Take the measure of what that verse says. The religion is declared perfected on a specific day. Not at the Prophet's ﷺ birth. Not at the first revelation in the cave of Hira. Not at the Hijra. Not at the conquest of Mecca. Not even at the close of the Farewell Pilgrimage a few days earlier. At Ghadir Khumm.

What can remain to be perfected in a religion whose creed, worship and law are already revealed? One thing only: who will hold it in trust. A building is not finished until the key has been handed over. Verse 5:67 opens the day by demanding the announcement; verse 5:3 closes it by declaring the work complete. Between the two, a single act: Ali's hand raised before the community.

And after the Prophet's ﷺ death?

The Prophet ﷺ died on 28 Safar in the year 11 of the Hijra, some seventy days after Ghadir.

While his family — Ali, Fatima, Hasan, Husayn — washed his body and prepared it for burial, a meeting was held under the portico of the Banu Sa'ida, the Saqifa, among Ansar and Muhajirun notables, to appoint a leader for the community. Ali was not invited. The proceedings ended in an oath of allegiance to Abu Bakr.

The designation made at Ghadir was not honoured.

There is no need to add invective. The fact, stated plainly, is enough: it is from this moment that the separation between Shia and Sunni arises. Not from hatred, not from a quarrel between personalities, not from an artificial schism constructed after the fact — but from a question of historical legitimacy, raised in the days following the Prophet's ﷺ death, which every Muslim has the right to know about and examine for himself.

Conclusion — why this concerns us today

Ghadir is not a squabble among historians. It is the question of who the Prophet ﷺ appointed to guide his community after him — and therefore, for any Muslim, the question of whom to turn to in order to understand Islam as it was taught.

What matters can be said briefly. The event is established: it is reported in the Musnad of Ahmad ibn Hanbal, in al-Tirmidhi, in Ibn Majah, and Ali's merit is attested by al-Bukhari and Muslim themselves. This evidence does not come from Shia sources: it comes from the heart of the Sunni tradition. The dispute concerns only the meaning of a word, and that meaning is fixed by the context, by the verse that commanded the announcement, by the Prophet's ﷺ own use of the same term for himself, and by the reaction of a witness who congratulated Ali on the spot.

Every year, on 18 Dhu al-Hijjah, millions of Muslims commemorate that day as Eid al-Ghadir, held in the Shia tradition to be the greatest eid of Islam — the day on which, according to a hadith related from Imam al-Sadiq, the religion was sealed.

The Ansar Al-Mahdi app places this event in your Hijri calendar and reminds you when the day comes, along with the other dates of the year.
