Abu al-Hajjaj, the ḥāfiẓ, told us: “This is the opinion most deserving of acceptance.

He explained: Al-Bukhari transmits the report in the Book of Adab ⦗1⦘, under the chapter ‘Being sociable with people’, stating: ‘ʿAbd Allah ibn Ṣāliḥ narrated to us, from ʿAbd al-ʿAzīz.’

He places it immediately after the hadith of Muḥammad ibn Sinān al-ʿAwqī, from Fulayḥ, from Hilāl.⦗2⦘
He also records it in the Sales section of the Jāmiʿ al-Ṣaḥīḥ ⦗3⦘, on the authority of al-ʿAwqī.

Accordingly, al-Bukhari possesses the hadith from both transmitters—in the Book of Adab and in the Ṣaḥīḥ … until he remarks:

“When it is established that he heard it from the two men, the wording ‘ʿAbd Allah ibn Ṣāliḥ narrated to us’ becomes shared between al-ʿIjlī the Kufan and al-Juhanī the scribe. Preferring the latter is more probable, because we are certain that al-Bukhari heard from the scribe of al-Layth and quotes him frequently in his History and elsewhere, whereas this is absent with regard to al-ʿIjlī. Al-Bukhari gives al-ʿIjlī only a very small and extremely concise entry in the History, from which he does not transmit anything, and we have never found a single verified narration of al-Bukhari from him—neither in the Ṣaḥīḥ nor in any of his other compilations. Rather, in the History he merely relates ‘from a man, from him.’

Indeed, we have located no narration of al-ʿIjlī from ʿAbd al-ʿAzīz ibn Abī Salamah except a single hadith whose text is: ‘Wrongdoing is layers of darkness.’⦗4⦘
That lone report was transmitted from him by Ibrāhīm al-Ḥarbī, whereas the scribe of al-Layth relates copiously from Ibn ⦗5⦘ Abī Salamah ⦗6⦘.
