I say: The explanation of what al-Bazzar stated summarily is as follows:
First: The hadith of al-A‘mash, through the aforementioned chain from this ‘Abd al-Rahman ibn Hasana: al-A‘mash explicitly stated that he heard it directly in one of al-Tahawi’s narrations, so the chain is authentic. As for his other hadith to which al-Bazzar alluded, it is found in Sunan Abi Dawud and elsewhere, through this chain of al-A‘mash from him, concerning taking precautions against urine. Ibn Hibban, al-Hakim, and al-Dhahabi likewise authenticated it. It is cited in Sahih Abi Dawud (16) and elsewhere.
Second: The hadith of ‘Adi ibn Thabit: Shu‘bah narrates it from him, from Zayd ibn Wahb, from Thabit ibn Wada‘ah, from the Prophet, peace and blessings be upon him, in an abbreviated form that does not mention overturning the pots. It was narrated by al-Nasa’i (2/199), Ahmad (4/320), and al-Tabarani in al-Mu‘jam al-Kabir (2/74/1365), with similar wording.
Husayn—namely, Ibn ‘Abd al-Rahman al-Sulami—also corroborated him, narrating it from Zayd ibn Wahb in the same manner. It was narrated by al-Nasa’i (2/198–199), as well as Abu Dawud (3795), al-Bukhari in al-Tarikh (1/2/170–171), Ibn Majah (3238), and al-Tahawi, all through Ibn Abi Shaybah. Ibn Abi Shaybah also recorded it in al-Musannaf (8/273/4415), as did Ahmad; and al-Tabarani (1366 and 1367) narrated it through several chains from him. Al-Nasa’i and others added: “I said, ‘O Messenger of Allah, the people have eaten some of them.’ He said, ‘He neither commanded that they be eaten nor forbade it.’”
This is an authentic chain, as al-Hafiz stated in al-Fath (9/663), after attributing it to Abu Dawud and al-Nasa’i. Yazid ibn Abi Ziyad also corroborated him: “I heard Zayd ibn Wahb al-Juhani,” narrating it in abbreviated form.
