Because nothing proves Imamate better than informing about...
Because nothing proves Imamate better than informing about the past and the future events. Like the proof of the messengership of Prophet Isa (a.s.) was that he informed the people what they ate and what they stored at home. In the same way was the case of the Holy Prophet (S). When Abu Sufyan said to himself: Has anyone done it the way I have done? I came and at once removed his hands from me. Then I gathered a large number of people of Kanana and Habasha, then I fought with him.
Perhaps I could have stopped him again. So the Holy Prophet (S) called out from his tent: O Abu Sufyan, now Allah will recompense you. This was like the proof of Prophet Isa bin Maryam (a.s.). And all such prediction made by the Imams (a.s.) prove that they are the true appointees of Allah and that it is incumbent to follow them.
And narrated to us Muhammad bin Hasan bin Ahmad bin Walid (r.a.) that: Narrated to us Saad bin Abdullah: Narrated to us Ja’far bin Muhammad bin Hasan bin Furat: Informed us Salih bin Muhammad bin Abdullah bin Muhammad bin Ziyad from his mother Fatima binte Muhammad bin Haitham known as Ibne Siyabah that she said: “I was in the house of Abul Hasan Ali bin Muhammad al-Askari (a.s.) when Ja’far was born. I saw the family members rejoice at the birth.
But when I came to Abul Hasan (a.s.) I did not see him happy at this. So I asked him: O my Sayyid, why do I see you unhappy at the birth of this child?
He replied: It will become clear to you because soon he will mislead a large number of people.” 3 - Narrated to us Shareef Abul Hasan Ali bin Musa bin Ahmad bin Ibrahim bin Muhammad bin Abdullah bin Musa bin Ja’far bin Muhammad bin Ali bin Husain bin Ali Ibne Abi Talib (a.s.) that he said: Narrated to us Abu Ali Muhammad bin Hammam: Narrated to us Ahmad bin Muhammad Naufali: Narrated to us Ahmad bin Hilal from Uthman bin Isa Kilabi from Khalid bin Najih from Hamza bin Humran from his father [Humran bin Ayyan] from Saeed bin Jubair that he said: I heard the Chief of the worshippers, Ali bin Husain (a.s.) say: “In His Eminence, Qaim (a.s.) are present similarities to seven prophets.
The practice of our father, Adam, the practice of Ibrahim, the practice of Musa, the practice of Isa, the practice of Ayyub and the practice of Muhammad (S). As for the practice of Adam and Nuh (a.s.) it is a long life. As for the similarity with Prophet Ibrahim (a.s.) it is a concealed birth and being away from the people. And from Musa it is the fear and occultation.
