I say: This is a good chain of transmission, despite the weakness of ʿAbd Allāh ibn Ṣāliḥ, the scribe of al-Layth. However, al-Ḥāfiẓ concluded from the statements of the imams regarding him that reports transmitted from him by highly proficient scholars, such as Yaḥyā ibn Maʿīn, al-Bukhārī, Abū Zurʿah, and Abū Ḥātim, are among his authentic hadiths. This is one of al-Bukhārī’s reports from him.

It is corroborated. Aḥmad (4/106) said: Abū al-Mughīrah narrated to us; al-Awzāʿī narrated to us; Usayd ibn ʿAbd al-Raḥmān narrated to me; Ṣāliḥ ibn Muḥammad narrated to me; Abū Jumʿah narrated to me, saying:

Usayd ibn ʿAbd al-Raḥmān had another shaykh as well. Usayd said: From Khālid ibn Durayk, from Abū Muḥayriz, who said: I said to Abū Jumʿah—a Companion—“Relate to us a hadith that you heard from the Messenger of Allah, peace and blessings be upon him.” He replied, “Yes, I shall relate to you a fine hadith...” Then he mentioned it.

Aḥmad recorded it, as did al-Dārimī in his Sunan (2/308). Both said: Abū al-Mughīrah narrated to us:
