He then cited it from al-Mughirah ibn Sa‘d, from his father—or from his paternal uncle—who said:
“I came to the Prophet, peace and blessings be upon him, at Arafah ...” He then mentioned a similar hadith. He said:
“Abd Allah narrated it in his supplementary material, and al-Tabarani in al-Kabir, through chains of transmission, some of whose narrators are trustworthy, although Yahya ibn ‘Isa is markedly weak.”
In summary, the hadith is authentic when all these routes are taken together, since most of them are free from severe weakness. Indeed, I consider the chain of transmission of al-Yashkuri to be good, at the very least on account of corroborating evidence. And Allah knows best.
What further strengthens it is that it has separate supporting reports in several hadiths, well known and widely transmitted in the Sahih collections and elsewhere—apart from the final passage. For that, if you wish, consult the hadith cited earlier under no. 72.
3509—“Treat the Ansar well—or, he said: honourably. Accept the good deeds of their virtuous ones, and overlook the wrongdoers among them.”
Ahmad recorded it (3/241), saying: Mu’ammal narrated to us; Hammad—that is, Ibn Salamah—narrated to us; Ali ibn Zayd narrated to us, saying:
News reached Mus‘ab ibn al-Zubayr concerning an official of the Ansar, and he intended to take action against him. Anas ibn Malik then entered upon him and said:
“I heard the Messenger of Allah, peace and blessings be upon him, say ...” He then mentioned it.
Mus‘ab threw himself down from his couch, pressed his cheek to the carpet, and said, “The command of the Messenger of Allah, peace and blessings be upon him, is upon my head and eyes.” So he left him alone.
I say: This is a weak chain of transmission, owing to Mu’ammal—who was Ibn Isma‘il—and Ali ibn Zayd—who was Ibn Jud‘an.”
