(It is narrated) from Ma'mar, from Yahya, from Ikrimah, from the Prophet (peace and blessings be upon him) as mursal (without mention of the Companion). Sufyan also narrated it from Ma'mar as mursal; likewise Abd al-Razzaq and Abd al-A'la narrated it from Ma'mar, and likewise Ali bin al-Mubarak narrated it from Yahya bin Abi Kathir, from Ikrimah, from the Prophet (peace and blessings be upon him) as mursal.
It has reached us from al-Bukhari that he declared weak the narration of those who narrated it as connected.
