[Abu 'Eisa said:] There is something on this topic from Al-Mughirah, and this Hadith is Gharib, we do not know of it being Marfu' except from this route. Sufyan and others reported it from Sulaiman At-Taimi, from Abu 'Uthman, from Salman as his own saying. It is as if the Mawquf narration is more correct. I asked Al-Bukhari about this Hadith and he said: 'I do not think it is preserved. Sufyan reported it from Sulaiman At-Taimi from Abu 'Uthman, from Salman in Mawquf form.' Al-Bukhari said: "Saif bin Harun is Muqarib (Average) in Hadith, and as for Saif bin Muhammad from 'Asim, his narrations are left."
