He said, “O people, who is more worthy ( 'awla ) (in the eyes of) the believers than their own selves?” They said, “Allah and His Messenger know better.” He said, “Allah is my Master and I am the master of the believers and I am worthier in their eyes than their own selves.
Whoever has me for his master has Ali for his master.” He said it thrice, and according to Ahmad, the imam of the Hanbalis, four times.[^1] The above proclamation at Ghadir Khumm regarding the wilaya of Imam Ali occurred in the last year of the Prophet's life (10 AH/632 AD).
Fourteen centuries have passed since then, and looking at the number of books and studies written on the subject of wilaya, both by the proponents as well as opponents, the proclamation at Ghadir Khumm proved to be one of the most pivotal events for the determination of the direction of the political-religious history of Islam.
Questions about the historicity of that event, whether raised by the Sunni scholars or by their western counterparts, who, more than often, followed the Sunni sources in their conclusions about the early history of Islam, have overlooked the political-religious implications of Ghadir Khumm on the subsequent conceptualization of Islamic leadership (imama) among Muslims in general.
The event at al-Juhfa, moreover, unfolded the Qur'anic presupposition in the matter of the direction that human society must follow in order to attain the final goal for which it has been created. On studying the Qur'an in its entirety the following general view emerges about human society which directly affects the question of leadership (imama) of that society.
To begin with, the Qur'an states more than once that Islam is not a new religion but the culmination of Allah's spiritual and temporal commands made known throughout human history through the mediatorship of divinely appointed prophets like Ibrahim (Abraham), Musa (Moses), Isa (Jesus), and the other prophets, the last in that line being Muhammad, peace be upon him. Thus, the prophet is the bearer of divine revelation that puts forth the divine commands for the guidance of humanity.
This guidance lays the foundation of human social organization by providing a set of laws and rules by which the believers manage their affairs and through which their public order is governed or should govern itself.
