So, the Prophet announced a general mobilization in Medina and its suburbs; an army of thirty thousand troops, in the severe heat which was fit for the ripening of fruits, announced their readiness to take part in this huge Islamic war. Some reporters gave the Prophet the news that the hypocrites of Medina were determined to kill innocent people in his absence. To stop any probable incident, the Prophet appointed Imam Ali (as) as his substitute in Medina.
Realizing the fact that their plan had been betrayed (by the Imam staying in Medina) they decided to employ a plot to make Imam leave Medina. For this reason, they spread a rumor that there were disagreements between Imam and the Prophet causing the Imam to be the side lines to the Prophet’s affection. The reason they presented for this rumor was the claim that Ali (as) was not permitted to take part in that religious war.
This rumor worried Imam Ali and his associates, who had always been loved by the Prophet. To falsify this statement, he approached the Prophet, who was not very far away from Medina, informing him of the story. To show his utmost love and care for Imam Ali (as), the Prophet delivered the following historical message: “Are you not willing to remain for me as Harun was for Musa? With the difference that there would be no prophet after me.
It is not proper for me to pass away without having appointed you as my successor. This narration, which is called the narration of Endearment by the Islamic reporters, is one of the most frequent and definitive narrations of Islam.
The narrator Buhrani, in his book called “Qayatul Maram” has mentioned the names of those authors who have reported this event in their books, showing that the Muslim narrators have reported this event in one hundred and seventy different ways, one hundred ways of which belong to the Sunnite scholars and narrators.[^1] Sharaf Al-din Ameli, in his book “Al-Morajeat” has reported the documents of this narration.
Reports by the Sunnite writers, state that it is narrated in ten books of theirs.[^2] On the authenticity of this narration it is enough for us to observe that the writers of Sahih (correct) books by the Sunnites, Bokhari and Muslim have reported this narration as the “right narration” in their books.[^3] In the firmness of these reports, it is sufficient to know that Saad Waqqas, Imam Ali’s (as) bitter enemy, considered this event as one of the three bright points in Imam Ali's life.
