The importance of Ghadir
Undoubtedly, Eid al-Ghadir is of paramount importance. It has been mentioned in Islamic traditions that this day is greater than even Eid ul-Fitr and Eid al-Adha. This does not reduce the importance of these two Islamic Eids. Its greater importance is just because it contains a loftier meaning. The importance of Eid al-Ghadir – which is the best Islamic Eid according to Islamic traditions – is due to the fact that it revolves around the issue of Wilayat. One may assume that the purpose of all the efforts made by the Holy Prophet (s.w.a.) and other divine prophets as well as religious luminaries was to establish divine Wilayat. The purpose of jihad and efforts for a divine cause has been explained in a tradition attributed to Imam Sadiq (a.s.): "In order to liberate people from following other human beings and guiding them towards worshipping God, and in order to liberate them from the Wilayat of human beings and bestow God's Wilayat on them." In the case of Eid al-Ghadir, there are two essential issues regarding Wilayat. Human nafs [self] is the first issue, and human beings should be able to accept the Wilayat of God's will over their nafs. This is the first and the most essential step that has to be taken before taking the next step. The second issue is bringing God's Wilayat into one’s society. That is to say, society should move ahead under God's Wilayat. No kind of Wilayat – Wilayat of money, Wilayat of tribes, Wilayat of ethnicities, Wilayat of power, and Wilayat of problematic customs – should prevent God's Wilayat, and His Wilayat should be dominant.
The person who was introduced as the Prophet's (s.w.a.) successor – namely, the Commander of the Faithful (a.s.) – was an exemplary role model in both aspects of Wilayat. He is the model of divine Wilayat in history both in terms of curbing his nafs – that is, the essential aspect of Wilayat – and in terms of the model of Islamic rule and divine Wilayat he presented and established. He is a perfect role model for those who are after divine Wilayat.
