It appears that this is how the report reached him, which is why he gave it the heading: “Mention that the Fire is incurred by one who makes the People of the Book hear what they dislike.” Al-Bazzār said after citing the hadith:

“We know of no one who narrated it from the Prophet, peace and blessings be upon him, other than Abū Mūsā through this chain of transmission, and I do not think that Saʿīd heard from Abū Mūsā.”

I say: This is because Abū Mūsā died in 53 AH, according to the most widely held view, whereas Saʿīd ibn Jubayr was born in 46 AH. Thus, at the utmost estimate, he experienced only six years of Abū Mūsā’s lifetime. This is something that al-ʿAlāʾī overlooked, for he did not mention it in Jāmiʿ al-Taḥṣīl; he should therefore rectify this omission.

Al-Nasāʾī also narrated the hadith in the exegesis section of al-Sunan al-Kubrā (6/363–364), through Khālid, from Shuʿbah, with the same chain.

Al-Haythamī cited it in full in al-Majmaʿ (8/261–262), but did not mention the words, “all religious communities.” He said:

“Al-Ṭabarānī narrated it—and this is his wording—and Aḥmad narrated something similar. The narrators in Aḥmad’s chain are narrators of the Ṣaḥīḥ, and al-Bazzār also narrated it in abbreviated form.”

I say: But Aḥmad has only the portion attributed to the Prophet.

From this source analysis and verification, we conclude that the soundest of these three routes is the first, because Ayyūb and al-Thaqafī agree upon it. Their agreement cannot be matched by Shuʿbah’s and Abū ʿAmr al-Baṣrī’s agreement in treating it as having a continuous chain, since they differ: the former places it among the reports of Abū Mūsā, whereas the latter places it among those of Ibn ʿAbbās. As for Shuʿbah, despite transmitting it with a continuous chain, it is interrupted between Saʿīd and Abū Mūsā, as stated above. As for Abū ʿAmr, you have learned from his biographical notice that he was not well-known; therefore, his contradiction of trustworthy narrators cannot be used as proof.
