Two observations:

First: Shaykh Shuʿayb erred in his annotation to Mushkil al-Athar (1/268), where he said of the hadith:

“Its chain of transmission is authentic according to the criteria of the two Shaykhs.”

Rather, it meets the criteria of Muslim alone, as noted above, for Yunus ibn ʿAbd al-Aʿla is not among al-Bukhari’s narrators.

Second: in his annotation to al-Nasa’i’s biographical notice in Tahdhib al-Kamal (2/328), he said:

“I must mention here a useful point that may escape many students of knowledge: when al-Mundhiri says in Mukhtasar Sunan Abi Dawud, ‘Al-Nasa’i reported it,’ he means the Sunan, not al-Mujtaba, which Ibn al-Sunni compiled. Likewise, when al-Hafiz al-Mizzi does so in al-Atraf, he means the original work, not the abridgment.”

I say: The first point is well known. As for the other, however, such an unqualified statement requires qualification, for al-Mizzi may also attribute reports in al-Atraf to al-Sunan al-Sughra, namely al-Mujtaba, as its distinguished editor, ʿAbd al-Samad Sharaf al-Din, explicitly stated in the introduction (1/18)—though I have a reservation concerning this which there is no occasion to mention now. In his annotation to Muqaddimat al-Mizzi (1/3), he attributed a hadith from Ibn ʿAbbas to the Book of Retaliation in two places (4/390 and 447). Yet this book is not among the books of al-Sunan al-Kubra, although its contents are found there under the Book of Waging War. That section also contains other hadiths found in the Book of Retaliation, which the aforementioned scholar imagined to be additional to those in al-Kubra.
