This cognizance were obtained according to the consecutive statements repeatedly addressed by the Prophet in the attendance of individuals as well as groups. Al­Madina is the capital of the Islamic state. Its people and their neighbors are the ones legally and actually concerned in the affair of nominating the leader and the Prophet's successor.

As the Lord willed that Muslims should apperceive congregationally that the next leader and the Prophet's successor would be Ali, He ordered His Prophet of acquainting them of this matter during the Farewell Pilgrimage so that none would disremember. This declaration occurred near a spring which carried the core of life at that deserted peninsula; water. That place which was called Khum was too distinct to be having an alike all over the Arab Peninsula.

Besides, that was the only place which carried the name Khum. Thousands of wonderments and probabilities are arisen from the declaration of that grand event that occurred before such a huge number of people in proportion of population of the world at that time. The attendants were of different degrees of faith, knowledge and cognition. This truth was taken in consideration during the Prophet's preparing and readying for delivering the divine mandate.

Hence, the Lord willed to fasten the Prophet's heart and find an excuse and regiment for conveying this divine mandate respecting nominating the coming leader and the Prophet's successor. Hence, the Verse of Tabligh — conveyance — was revealed. The Verse of Tabligh Instantly, the Angel Gabriel descended carrying the Verse of Tabligh to the Prophet: (O Apostle!

Deliver what has been revealed to you from your Lord; and if you do it not, then you have not delivered His message, and Allah will protect you from the people; surely Allah will not guide the unbelieving people. 5:67) The future of the Islamic mission depended upon this conveyance. On the eighteenth of Dhul­Hijja, this Verse was revealed in Ghadeer Khum. It was the same day on which the Prophet designated Ali as people's head, leader and his successor.

That was on Thursday.[98] [98] bn­Asakir's Tarikhu Dimeshq Chapter: The Life Account Of Ali Bin Abi Talib part.2 page86. Siddiq Hassan Khan's Fetihul­Beyan Fi Meqassidil­Qur'an part.3 page63.
