and Ibn Abī Laylá is Muḥammad ibn ʿAbd al-Raḥmān ibn Abī Laylá, and he is weak in terms of his memory. He narrated it once with another isnād; Aḥmad said (5/402): Wakīʿ narrated to us from Ibn Abī Laylá from a shaykh called Hilāl from Ḥudhayfah who said: I asked... the ḥadīth. And likewise said Ibn Abī Shaybah. The correct narration is his first one from Abū Dharr, corroborated by the narration of Abū Baṣrah al-Ghifārī and Mujāhid from him. And Allāh knows best.

I said: And this ʿAbd al-Raḥmān, despite being one of al-Bukhārī's narrators, has weakness in his memory; the ḥāfiẓ has deemed him acceptable in "al-Fatḥ"; he said under this ḥadīth (12/420): "There is disagreement about him; Ibn al-Madīnī said: He is truthful. Ibn Maʿīn said: In my view, his ḥadīth is weak. Al-Dāraquṭnī said: Al-Bukhārī disagreed with people about him; he is not abandoned. I said (the ḥāfiẓ):
