In the book “Rawdat al-Muttaqin” part 5 page 440 under “Kitab al-Hajj” in the section of the visit of the grave of the two Imams Musa bin Ja’afar (rah) and Abu Ja’afar al-Thani (rah), the Shia scholar al-Majlisi accuses the other Shia scholar al-Saduq of altering the Du’ah which has to be said at their graves in Baghdad.
“From the narrations that the author(al-Saduq) has mentioned are some that have been narrated by al-Kulayni in al-Kafi from the Hadith of Muhammad ibn Ja’afar al-Razzaz al-Kufi from Muhammad bin ‘Isa bin ‘Ubeid from he who mentionned it from Abu al-Hassan (as): “Say in Baghdad: Peace of Allah be upon you O Wali of Allah – Peace of Allah be upon you O Hujjah of Allah – Peace of Allah be upon you O light of Allah in the darkness of the earth – Peace of Allah be upon you whom Allah had al-Badaa concerning you, I came to you knowing your right and opposing your enemies so intercede for me with your Lord, then ask Allah for your Hajat and for what you need, he said: And you send peace on Abu Ja’afar like this.(1)”
“The author(al-Saduq) removed the part that says [Peace of Allah be upon you whom Allah had al-Badaa concerning you] because he does not believe that Allah had al-Badaa concerning Ismail ibn Ja’afar although we see that the narrations about al-Badaa are Mutawatir and cannot be rejected so that we could leave this saying”

Basically the Shia scholars believed that the Imamah went to Ismail ibn Ja’afar after Ja’afar al-Sadiq, this was the opinion of the Shia but then Ismael died in his father’s life which caused a HUGE division in the Shia sect and most of the Shia scholars and laymen were confused, what they did was they invented this concept called “al-Badaa” which means: “it had appeared to Allah that the Imamah would go to Ismael bin Ja’afar but then the circumstances changed and he gave it to Musa bin Ja’afar.”
