Technical note / Defect ('illah): In manuscripts (M) and (S) the name has been corrupted into "al-Bara'", whereas the correct name is the one in manuscript (B), and it is like this in more than ten places in the author's (al-Hakim's) book.
Note / Clarification: We have supplied the part in square brackets from those other places, because this 'Abd Allah al-Ghazzal, in the author's book, narrates from Ibn al-Mubarak only through Ibn Shaqiq.

Technical note / Defect ('illah): In the manuscripts it has been corrupted here into the word "'an".

Grading: This hadith is "hasan", if Allah wills. This chain is weak, because 'Abd Allah al-Ghazzal is majhul (unknown) and Muhammad bin Abi Hafsah is not strong, but both of them are corroborated.
Technical note / Defect ('illah): There is also a disagreement over al-Zuhri in it (as explained in Musnad Ahmad 25/ 15750), but all the narrations from al-Zuhri together show that he took it from some members of Abu Lubabah's household. See also our commentary on hadith number (3319) of "Sunan Abi Dawud".
Reference / Source: al-Tabarani narrated it in "al-Kabir" (4509) via Nu'aym bin Hammad, from 'Abd Allah bin al-Mubarak, with this same chain.

Reference / Source: Imam al-Bukhari also narrated it in "al-Tarikh al-Kabir" (2/ 386) via Sa'id bin Yahya bin Salih, from Ibn Abi Hafsah, from al-Zuhri, from al-Husayn bin al-Sa'ib or someone else.

Reference / Source: Imam Ahmad narrated it (25/ 15750 and 16080) from Rawh, from Ibn Jurayj, who said: Ibn Shihab (al-Zuhri) informed me that al-Husayn bin al-Sa'ib bin Abi Lubabah reported that when Allah accepted the repentance of Abu Lubabah bin 'Abd al-Mundhir, and he mentioned the hadith.
