Eid al-Ghadir

Ten years after the migration (Hijrah), the Islamic prophet Muhammad ordered his followers to call upon people everywhere to join him in his first and last pilgrimage. Islamic scholars believe more than seventy thousand people followed Muhammad on his way to Mecca, where, on the fourth day of the month of Dhu'l-Hijjah, there were more than one hundred thousand Muslims present for his entry into the city.^[9][10] While returning from this pilgrimage, on 18 Dhu'l-Hijjah 10 AH (March 632 CE) at an area known as Ghadir Khumm, Muhammad delivered a well-known sermon during which he called up his cousin, brother, and son-in-law Ali ibn Abi Talib and declared, "to whomsoever I am Mawla, Ali is also their Mawla". The meaning of the word Mawla can be interpreted as "master", and thus many see the sermon as being the official designation of Ali as Muhammad's successor.^[11] As a result, the date of the sermon is considered to be one of the foundational events of Shia Islam, with the anniversary becoming one of its most important annual celebrations as "Eid al-Ghadir".^[12][13] To be more precise, Muhammad declared "Do I have more authority over you than you do yourselves?" They responded with "Yes oh prophet of Allah" He continued with " Then, to whomsoever I am Mawla, Ali is also their Mawla". While the meaning of the word Mawla can be interpreted as "friend" (as it has many meanings), the question asked set the context for it to be interpreted as "master" and in turn suggested “leader”.

In a hadith attributed to Muhammad recorded by Ibn Babawayh, Muhammad considers Ghadir Khum to be the best and highest of the festivals of his Ummah.^[14] Shia Muslims throughout the world celebrate this event annually with diverse customs.^[15][16] It is held in different countries, including Iran,^[17][18][19] India, Pakistan, Azerbaijan,^[20] Iraq,^[21][22] UAE, Yemen, Afghanistan, Lebanon, Turkey,^[23] Bahrain, and Syria. Shia Muslims also celebrate Eid Ghadir in Europe and the Americas, including the United States, Canada, United Kingdom, Germany, France.^{[24][25][26][27]}

According to some historical accounts, the commemoration of the event of Ghadir Khum was held as a festival since the first centuries of Islam, for the first time during the Buyid era, then during the Safavid era, the Eid al-Ghadir was one of the largest religious festivals celebrated. The celebration also gained special importance during the Qajar era, as on this day, an official greeting ceremony was held with great ceremony in the court. The custom of greeting the king on this day continued during the Pahlavi era.^[28] In 2022, a 10-km long festival was held in Tehran marking the Ghadir ceremony with hundreds of thousands of the people pouring out into Valiasr Street and the nearby streets.^[29]

In 2024, a massive celebration was held in multiple Yemeni Provinces where fireworks, bands, and speeches were held. In recent years, Eid Al-Ghadir (known in Yemen as Yom Al-Wilaya) has been celebrated more than ever since the Zaydi Shia Government took over Yemen.^[30][31] Also in the same Year the Iraqi Parliament declared Eid al-Ghadir to be an official public holiday with the encouragement of the Sadrist Leader, Muqtada al-Sadr.^[32]

According to the narrations, Hassan ibn Ali used to hold ceremonies in Kufa on the day of Ghadir. Ali ibn Abi Talib used to participate the ceremony accompanied by a group of his followers. After the ceremony, Hassan ibn Ali would give people gifts. Greeting, hand shaking, wearing new clothes, using perfume, making donations, helping others, saying prayers, feeding others, making others happy and giving gifts to others are among the suggested customs reported in narrations.^[33]
