The Twenty-Seventh Assembly, which is Friday, the First of Muharram, 367 AH. He delivered it after he returned from the Shrine of al-Rida (as)

a man came to him and said to him: O Abu’l Hasan! You are called the Amir al-Mu’minin; so, who ordered you over them? He (as) said: Allah ordered me over them. So, the man came to the Messenger of Allah (s) and said: O Messenger of Allah! Does `Ali speak the truth when he says that Allah ordered him over His creation? The Prophet (s) was enraged, and he said: Surely, `Ali is the Amir al-Mu’minin through guardianship from Allah; it was awarded to him over His Throne. The angels have borne witness that `Ali is the vicegerent of Allah and the Proof of Allah and that he is the Imam of the Muslims. His obedience is coupled with the obedience of Allah and his disobedience is coupled with the disobedience of Allah. So, whoever was ignorant about him, he is ignorant about me and whoever recognised him, indeed he has recognised me. And whoever denied his Imamate, he has denied my prophethood and whoever denied his rulership has denied my messengership. And whoever refuted his superiority, he has lowered me and whoever fought with him he has fought with me. And whoever insulted him he has insulted me, for he is from me, created from my clay and he is the husband of Fatima, my daughter, and the father of my sons, al-Hasan and al-Husayn. Then he (s) said: Surely, I and `Ali and Fatimah and al-Hasan and al-Husayn and nine from the sons of Husayn are the Proofs of Allah upon His creation. Our enemies are the enemies of Allah and our friends are the friends of Allah.

Yazid b. Qa`nab said: I was sitting with al-`Abbas b. `Abd al-Muttalib and a party of the tribe of `Abd al `Uzza were near the Sacred House of Allah when Fatima bt. Asad, the mother of Amir al-Mu’minin (as), who was nine months pregnant and overtaken by labour pains, approached. She said: My Lord! Surely, I am a believer in You and in what has come from You of the messengers and the books. And I am a believer in the word of my grandfather, Ibrahim the Friend (as), who laid the foundation of the Ancient House. So, for the sake of the one who laid the foundation of this House and for the sake of the child who is in my womb, with whom I have come to You, facilitate my delivery for me.
Yazid b. Qa`nab said: We saw the House open at its back and Fatima enter therein and disappear from our sight, and the wall came together [again]. We tried to get the lock of the door to open for us, but it did not open. So, we knew that the decree was from Allah’s command.
Then, she came out after four days, and in her hand was Amir al-Mu’minin (as). And she said: I have excellence over all the women who have preceded me because Asiya bint Muzahim worshipped Allah in secret in a place where it is not liked that Allah be worshipped therein save under compulsion. And Maryam bint `Imran had to shake the dried date palm until she ate ripe fruits from it, while I entered the Sacred House of Allah and ate from the dates of Paradise and its sustenance.
When I desired to come out, a crier called out to me: “O Fatima! Name him `Ali, for he is `Ali and Allah is al-`Ali (the High) al-A`la (the Most High). He (Allah) says: I have split his name from Mine and trained him Myself and made him fit for the mystery of My knowledge and he is the one who will break the idols in My House and he is the one who will call towards prayer on top of My House. He will glorify Me and he will exalt me. So, glad tidings to the one who loves him and obeys him; and woe to the one who holds malice for him and disobeys him.
