“When the last moments of Imam Muhammad Baqir (a.s.) approached, he summoned his son, Imam Ja’far Sadiq (a.s.) and took the oath of Imamate from him. The brother of Imam Muhammad Baqir (a.s.), Zaid bin Ali bin Husain said: O Brother, why don’t you let the matter proceed like in the case of Imam Hasan (a.s.) and Imam Husain (a.s.)? The Imam said: Abul Hasan, Imamate is not transferred by emulation and it is not given from one to another by way of a custom. It is one of the decided proofs of the Almighty. Then the Imam called for Jabir bin Abdullah and said: O Jabir, narrate to me the tradition about what you saw in the scroll of Fatima. Jabir said: Yes, O Abu Ja’far, one day I went to the house of Fatima to offer greetings at the birth of Imam Hasan (a.s.). I saw in the hands of Fatima, a scroll in a white binding. I asked: O chief of the ladies, what scroll is this? She said: It contains the names of the Imams from my progeny. I said: Can I see it? She replied: Only the Prophet, the successor of the Prophet and his Ahle Bayt (a.s.) can touch this scroll. If this restriction had not been there I would have given it to you. But I can permit you to see it without touching it.
Jabir says: I read this scroll. It was written therein: Abul Qasim Muhammad bin Abdullah Mustafa, whose mother is Amina binte Wahab, Abul Hasan Ali Ibne Abi Talib al-Murtuza, whose mother is Fatima binte Asad bin Hashim bin Abde Manaf, Abu Muhammad Hasan bin Ali al-Birr, Abu Abdullah Husain bin Ali Taqi, both of whose mother is Fatima binte Muhammad, Abu Muhammad Ali bin Husain al-Adl whose mother is Shaharbano binte Yazdjird Ibne Shahanshah, Abu Ja’far Muhammad bin Ali al-Baqir whose mother is Umme Abdullah binte Hasan bin Ali Ibne Abi Talib (a.s.), Abu Abdullah Ja’far bin Muhammad as- Sadiq whose mother is Umme Farwa binte Qasim bin Muhammad bin Abu Bakr, Abu Ibrahim Musa bin Ja’far Thiqa whose mother is a slave wife named Hamida, Abul Hasan Ali bin Musa ar-Reza whose mother is a slave wife named Najma, Abu Ja’far Muhammad bin Ali Zaki whose mother is a slave wife named Khizran, Abul Hasan Ali bin Muhammad Amin whose mother is Susan the maid, Abu Muhammad Hasan bin Ali Rafiq whose mother is Samana the maid and her patronym was Ummul Hasan, Abul Qasim Muhammad bin Hasan, the proof of Allah on the creatures whose mother is Narjis the maid slave; peace of Allah be on them all.”
