H 167- Saad bin Abdullah Ashari has narrated: Narrated to me Abu Hashim Dawood bin Qasim Ja’fari that:

When Abu Ja’far passed away, I was present with Imam Hadi and previously the Imam had hinted to him. Therefore, I thought and said to myself: This is just how it happened in the case of Abu Ibrahim [Imam Kadhim ] and Ismail Ibn Ja’far that when Ismail passed away, Imam Sadiq publicly announced his death so that no one may say that Ismail or his descendants are Imams. Imam Hadi came to me and said: Yes, Aba Hashim, change of destiny occurred (Bada) with regard to Abu Ja’far and Almighty Allah replaced him with Abu Muhammad as He did in the case of Ismail, son of Imam Sadiq , after Imam Ja’far Sadiq had declared and mentioned him to be the Imam after him and appointed him as his successor; just as you said to yourself, although it would be displeasing to the followers of falsehood. My son, Abu Muhammad is my successor and he is having all that which the Shia society is in need of and he is having the distinctive signs of Imamate, by the grace of God.
