This isnad is unknown to me; I recognize no one in it except Malik ibn Anas and Nafiʿ. Yet al-Haythami said, “Al-Tabarani recorded it in al-Kabir and al-Awsat, and the men in its chain are trustworthy.”
It has also been reported from Ibn ʿUmar on the authority of Abu Saʿid, namely:
Seventh: Abu Saʿid al-Khudri
Al-Khatib (4/403) narrated it through Ahmad ibn Muhammad ibn Jahur, who said: “ʿAffan narrated to us; ʿAbd al-Waḥid ibn Ziyad narrated to us; Ishaq ibn Sharqi, the client of Ibn ʿUmar, narrated to us and said: Abu Bakr ibn ʿAbd al-Rahman narrated to me from Ibn ʿUmar, who said: Abu Saʿid al-Khudri narrated to me,” tracing it back to the Prophet with the same wording.
Al-Khatib cited the report under the biography of this Ibn Jahur but offered neither criticism nor endorsement of him.
As for Ishaq ibn Sharqi, I could not locate a biography for him. Nonetheless, al-Haythami commented, “Al-Tabarani transmitted it in al-Awsat, and it is, God willing, a hasan (sound) hadith.”
I add: Ahmad (3/4) also recorded it: Rawḥ narrated to us; Malik ibn Anas narrated to us from Khubayb ibn ʿAbd al-Rahman, that Ḥafṣ ibn ʿĀṣim informed him from Abu Hurayrah and Abu Saʿid, tracing it back to the Prophet with the same wording.
This isnad is composed of narrators employed by the two Shaykhs (al-Bukhari and Muslim), yet it has been transmitted with conflicting wording from Malik, as noted earlier; the correct version is that it goes back to Abu Hurayrah alone. (1)
