It was Almighty God who selected and appointed ‘Ali, followed by the Immaculate Imams of his progeny, as the next leaders of the Islamic Ummahh after the Prophet. This decision was conveyed by the Prophet from the earliest stage of the march of Islam.[^3] In almost all occasions that gathered Muslims, the Prophet confirmed that ‘Ali would succeed him in the leadership of the Islamic Ummahh. The event of Ghadir Khum is a clear-cut proof on our claim.
Ahead of about one hundred thousand Muslims whom were gathered in that terribly hot weather, the Prophet (S) raised ‘Ali’s hand to declare that this man must be regarded as the leader of everyone who adopted the leadership of the Prophet, and ordered the present ones to convey this decision to the absent, including the coming generations.
In addition, he gave orders of holding special ceremonies on that occasion and took the pledge of all Muslims’ men and women to recognize the leadership of Imam ‘Ali.
The anniversary of that occasion is still celebrated by Muslims who fulfilled their pledge to the Prophet.[^4] As a hopeless endeavor, the Koreishite chiefs, supported by some Koreishite individuals who were among the first converts to Islam but showed loyalty to the Koreishite conspirators, came to the Prophet to suggest that he had better cancel his decision of appointing ‘Ali as the coming leader…etc.[^5] But the Prophet refused their demand, emphasizing that the matter was God’s and not based on anyone’s desire.
The Prophet used nice policy with those defeated chiefs. For instance, he appointed their military commander, Abu-Suffian ibn Harb, as a tax collector. But, they kept on their plots and wicked intentions. They, once demanded for autonomy, but the Prophet (S) reproached and threatened to ask his hero, ‘Ali ibn Abi-Talib to fight them. He also predicted that the Koreishites would not stop plotting against Islam unless they were made to submit by force[^6].
Finally, the Koreishites despaired of getting any success with any of their plots as long as the Prophet (S) was alive. Hence, they prepared new matters that would be done after his death. After the Prophet When the Prophet (S) departed from this life after he had been prevented from dictating his will,[^7] a great turning in the march of Islam occurred.
