The holy prophet said:Ghadir is the noblest and the most significant Eid of the Muslim Ummah and the free-minded people across the world.
Imam Khomeini has also said:
What can I say about the personality of Imam `Ali? Who else may justly say anything about him? The multifarious dimensions of this great personality are beyond human assessment. Just like the names of God, the Exalted, the dimensions of a perfect man, who is the manifestation of all divine names and attributes, are beyond calculation. We cannot describe even a single attribute of Imam Ali… The issue of Ghadir is not an event befallen the Imam. In fact,Ghadir has been created for the sake of the Imam. This noble personality and fountainhead of sound human qualities prompted the Ghadir to take place. The Ghadir itself has no value for Imam Ali. What is valuable is his Excellency for whom Ghadir is valued. (Sahifeh-ye Imam, vol. 20, p. 106)
Ghadir is not only designed to reflect a specific divine day but also it highlights a course of history. It is the comprehensive code of life, belief and school of thought. It also underscores the glad-tiding of a pleasant sun rising. By raising Imam Ali’s hand and introducing him as the source and guardian of Islam, the holy prophet guaranteed his divine mission and rescued it from the evil powers.
Ghadir is the continuation of the prophet’s mission and the torch-bearer of monotheism, which shows the dignity of Muhammad’s progeny.Ghadiris the completion of the religion,the perfection of God’s greatest bounty, the most magnificent feast of Allah;it is the feast for the righteous people, followers and supporters of the holy Prophet of Islam. Ghadir is the feast of Islamic justice and leadership, the feast of humanity, projecting light on the ideologies and inducing hopes in the hearts. It is the renewed covenant of the prophet’s missionin the guardianship of Imam Ali (’a).
