“...al-Thiqat [The Trustworthy Narrators].” It is found in Musnad Abu Ya‘la (1979); see what precedes it.
Their oversight has two aspects:
First, Hushaym’s use of an unqualified “from” transmission prevents the chain of transmission from being declared authentic, as explained above. This is the first point.
Second, the fact that Isma‘il ibn Salim, Ahmad ibn Mani‘, and Surayj ibn Yunus all narrated from Hushaym in Ibn Hibban’s collection with an explicit statement of direct narration, but without the hadith cited in the heading, renders Zahmawayh’s narration with this addition anomalous.
Third, the corroboration of Hushaym by the body of trustworthy narrators who transmitted the hadith from Husayn without this addition confirms its anomalous nature. This is why al-Bukhari and Muslim confined themselves to recording the hadith without it.
The other aspect is that each of the two commentators referred to Abu Ya‘la’s version, which agrees with the preceding version of al-Bukhari and Muslim. That is the height of oversight!
Moreover, the addition, “And he said, concerning the twelve ...,” is established through some other routes from Hushaym in Ibn Hibban, Muslim, and others as well.
Nevertheless, the hadith cited in the heading has a strong mursal supporting report. Al-Tabari said in his Exegesis (28/67–68): Bishr narrated to us; he said: Yazid narrated to us; he said: Sa‘id narrated to us, from Qatadah:
“While the Messenger of Allah, peace and blessings be upon him, was delivering the Friday sermon to the people, they began slipping away and rising to leave, until only a group of them remained. He said, ‘How many of you are there?’ They counted themselves, and there were twelve men and one woman. Then, on the following Friday, he stood and began delivering the sermon to them.” Sa‘id said: “As far as I know, his report included: ‘He admonished and reminded them.’ Then they began slipping away and rising to leave, until a group remained. He said, ‘How many of you are there?’ They counted themselves, and there were twelve men and one woman. Then, on the third Friday, he stood...,”
