[Abu 'Eisa said:] This Hadith is Hasan Gharib, we do not know of it except from a narration of Al-Hakam. Al-Hajjaj bin Artah also reported it from Al-Ahkam. Ahmad bin Al-Hasan said: "I heard Ahmad bin Hanbal saying: 'Ibn Abi Laila's narrations are not used as proof." Muhammad bin Isma'il said: "Ibn Abi Laila is truthful, but his correct Ahadith are not recognizable from his weak ones. And I do not report anything from him." Ibn Abi Laila is truthful, and Faqih, the problem is only in the chain.
Nasr bin 'Ali narrated to us, [he said:] "Abdullah bin Dawud narrated us, from Sufyan Ath-Thawri who said: 'Our Fuqaha' are Ibn Abi Laila and 'Abdullah bin Shubrumah.'"
