Eid al-Ghadir:
The Day Allah Completed Islam

What Is Eid al-Ghadir?

On the 18th of Dhul Hijja, 10 AH — approximately March 632 CE — the Prophet Muhammad ﷺ made the most consequential public announcement of his entire prophethood. At a place called Ghadir Khumm, a crossroads on the caravan route between Mecca and Medina, he halted an army of returning pilgrims estimated between 70,000 and 120,000 people, stood on a pulpit built from camel saddles, and delivered a declaration that would define the course of Islamic history forever.

Eid al-Ghadir — celebrated every year on 18 Dhul Hijja — commemorates this event. Shia Muslims regard it as the greatest Eid of the Islamic calendar: greater than Eid al-Fitr and Eid al-Adha, because it marks the day the Prophet ﷺ completed his mission by divine command. Understanding what happened at Ghadir, and what the Quran says about it, is essential for any Muslim who wishes to know their religion in full.

What Happened at Ghadir Khumm?

The Prophet ﷺ had just completed the Hajjat al-Wada' — his one and only Hajj — when the Angel Jibreel descended with a divine command that could not be delayed. The entire caravan was brought to a halt in the valley of Ghadir Khumm, in what is now the Hijaz region of Saudi Arabia.

   The Divine Order to Stop

   Allah commanded the Prophet ﷺ to halt the entire caravan — those who had walked ahead were called back, those behind were waited upon. No one was to proceed until all 70,000–120,000 pilgrims had gathered and heard what was to be said.

2. 2

   The Pulpit of Camel Saddles

   A makeshift pulpit was erected from stacked camel saddles and luggage. The Prophet ﷺ ascended it so his voice could carry across the vast crowd in the midday heat. He led a congregational prayer, then delivered a lengthy sermon reminding the people of his imminent departure from this world.

3. 3

   The Declaration of Mawla-ship

   The Prophet ﷺ took the hand of Imam Ali ibn Abi Talib (عليه السلام) and raised it in the air. He asked the crowd three times: "Am I not your Mawla — more worthy of authority over you than your own selves?" All affirmed. He then declared: "Whoever's Mawla I am, Ali is his Mawla."

   Revelation of the Completion Verse

   Following this proclamation, the verse of Surah al-Ma'idah 5:3 — "This day I have perfected your religion for you" — descended as divine confirmation that the mission of prophethood had now been fully fulfilled.

   Three Days of Congratulations

   The Companions offered formal tahni'ah (congratulations) to Imam Ali for three days. Among the very first to congratulate him were Abu Bakr and Umar ibn al-Khattab, who said: "Congratulations, O son of Abu Talib — you have become the Mawla of every believing man and woman."

The Hadith of Ghadir is among the most mass-transmitted (mutawatir) narrations in Islamic history. Al-Hakim al-Naysaburi declared it sahih on the criteria of both al-Bukhari and Muslim; Imam al-Dhahabi confirmed this. Its narration from over 110 Companions in the first generation makes any denial of the event itself historically untenable.

The Command to Convey — Or Risk All Being Lost

Before the Prophet ﷺ made his announcement at Ghadir, this verse descended — commanding him in the most urgent possible terms to deliver a specific message, with a stark and unprecedented warning attached:

The structure of this verse is extraordinary. The Prophet ﷺ had spent 23 years conveying revelation — every command, prohibition, and ruling. Yet Allah says this single undelivered message is so weighty that its absence would render the entire prophetic mission as if it had never happened. The phrase "Allah will protect you from the people" implies the Prophet ﷺ anticipated a reaction — that this message would provoke controversy. No routine legal ruling requires a divine bodyguard assurance.

What Was Conveyed After This Verse?

After verse 5:67 commanded the Prophet ﷺ to make the announcement without delay, he raised the hand of Imam Ali and delivered the declaration recorded in Hadith al-Ghadir. He then made the following supplication — completing the covenant:

Following this declaration and supplication, the verse of completion (5:3) descended — Allah's own confirmation that the announcement had been made and the mission was now fulfilled.

"This Day I Have Perfected Your Religion" — The Completion Verse

After the proclamation at Ghadir, this portion of verse 5:3 was revealed — and it is among the most celebrated and debated revelations in the entire Quran:

The word al-Yawm (الْيَوْمَ) — "This Day" — is the interpretive key. It does not refer to a day long in the past; it points to the specific day of the verse's revelation. The central question for all scholars is: what event on which day made the religion complete? Everything before this day was apparently incomplete — what was the final, missing element?

Three Days of Congratulations — How the Sahaba Responded

One of the most historically documented aspects of the Ghadir event is the three-day formal gathering of Companions to offer their tahni'ah (congratulations) to Imam Ali. This detail is found in Sunni hadith collections, not only Shia sources.

The significance of the word tahni'ah cannot be overstated. In Arabic, you congratulate someone upon receiving a rank, honour, or position — not upon being mentioned in a general speech. The use of this term by the Companions — including the two men who would later become the first and second caliphs — confirms that they understood the Prophet's ﷺ declaration to be an appointment to a position of authority, not merely a statement of personal affection.

Hassan ibn Thabit, the official poet of the Prophet ﷺ, composed verses on that very day with the Prophet's ﷺ permission, immortalising the event. His poem declared that the Prophet ﷺ called on them on the Day of Ghadir to acknowledge Ali as their Imam and leader after him.

The Importance of Eid al-Ghadir

After Ghadir — A Turning Point in Islamic History

The Prophet ﷺ lived for approximately 70 days after Ghadir before passing away in Safar of 11 AH. In those remaining weeks, he repeatedly reinforced the theme of Ghadir — most notably through the declaration of the Hadith al-Thaqalayn:

Despite the unambiguous events of Ghadir, the succession following the Prophet's ﷺ death went to Abu Bakr, then Umar, then Uthman — before Imam Ali finally assumed the Caliphate in 35 AH, over two decades after Ghadir. For Shia Muslims, this interval is not a minor political disagreement — it is a theological rupture whose consequences echo through all of Islamic history, culminating most tragically in the martyrdom of Imam Husayn (grandson of the Prophet ﷺ and son of Imam Ali) at Karbala in 61 AH.

Understanding Fiqh Jaffari — the jurisprudence of the School of the Ahlulbayt, which flows directly from the authority established at Ghadir — is one of the most important pillars of Shia Islamic education. At ShiaEdu, this is taught through live one-to-one classes for all ages.
