Bismillah.
Salam alaikum.
Shaykh of shias al-Mufid narrrated in his book al-Ihtisas (P18):
عن جابر بن يزيد، عن أبي جعفر عليه السلام في قول الله تبارك وتعالى: ” عسى أن يبعثك ربك مقاما محمودا ” قال: يجلسه على العرش معه
From Jabir ibn Yazid from Abu Jafar (alaihi salam) which said about words of Allah (17:79) “maybe your Lord will raise you to a position of great glory” – HE WOULD SIT HIM ON THE THRONE WITH HIMSELF
al-Majlisi in his “Biharul anwar” (16/377-378) wrote:
89 – ختص : عن جابر بن يزيد ، عن أبي جعفر عليه السلام في قول الله تبارك وتعالى عسى أن يبعثك ربك مقاما محمودا ” قال : يجلسه على العرش
89-1 (Ihtisas) – from Jabir ibn Yazid from Abu Jafar (alaihi salam), which said about words of Allah tabaraka wa taala “maybe your Lord will raise you to a position of great glory” – HE WOULD SIT HIM ON THE THRONE!
As you can see word “with him” miraculously disappeared!
Assalāmu `Alaykum,
I think this is not a big deal, this is just a nuskh issue between copyist errors. There are a few manuscripts of al-Ikhtisās, see al-Tehrani’s Dharī`ah where mentions them.
Not to forget, this book is rejected by al-Khoei and others.
