When Muawiyyah entered Mecca to receive people's allegiance for his son...
When Muawiyyah entered Mecca to receive people's allegiance for his son, Yazid, he convened an assembly in “Al-Nadut” in which some dignitaries of the Prophet's close friends had taken part. He started his statement with cursing Ali (as) and expected Saad to join him in this condemnation, but addressing Muawiyyah, Saad replied: whenever I remember Ali's three virtues, I wish I could have those three virtues.
Those virtues being: The day when the Prophet told Ali that Ali was to him as Harun was to Musa; During the Khaybar Holy war, the Prophet said: Tomorrow I will give the flag to an individual who is loved by Allah and by His Apostle. He would be the conqueror of Khaybar and would not flee the enemy, (and then he gave Ali the flag).
On the day of Mubahilah (cursing) with the Christians of Najran, the Prophet gathered Ali, Fatima, Hasan and Husain, saying: O God, these are my Household.[^4] Therefore, we should not ever doubt the validity and authenticity of this document; rather we should step forward and try to think over the content of this narration. Firstly, we should stress on the expression الاّ انه لا نبي بعدي except for the fact that there would be no prophet after me.
In this narration, the Prophet likens his relation to Ali's to the relation of Harun and Musa. However, this narration takes away the position of prophethood from Ali (as) despite the fact that Harun was a prophet. This is related to the command used in the title وخاتم النبيّين “the last of the Prophets” and so Ali (as) would never attain such a position.
Now let us see what kind of positions and titles Harun possessed in accordance with the Holy Quran; Ali (as) possessed all these positions except for the position of prophethood. When we refer to the Holy Quran, we observe that Musa (Musa) had asked God to bestow upon Harun the following positions: The position of minister: Musa Ibn Omran had asked Allah to appoint Harun as his minister: “And give me a helper from my family, Harun, my brother “[^5].
Strength and confirmation: Musa asked Allah to confirm him through his brother Harun: “Strengthen my back through him “. Prophethood: Musa Ibn Omran asked Allah to join Harun in the affair of prophethood: “And associate him with me in my affair”[^6].
