“trustworthy.” I say: He was not among the transmitters of either of the two Shaykhs, nor indeed of the remaining four, contrary to what al-Hakim’s wording might suggest, even though al-Dhahabi agreed with him.
As for Ibn Khuzaymah, he deemed it defective because Yahya narrated it with an unspecified “from” link. He said: “...if Yahya ibn Abi Kathir heard this report from ʿAbd Allah ibn Abi Qatadah.” I say: Both Shaykhs and others accepted him as proof; thus, it appears that his use of an unspecified “from” link is problematic only in what he narrated from Anas and the like. And Allah knows best.
As for al-Manawi’s statement in al-Fayd, following al-Hakim’s preceding statement: “Al-Dhahabi critiqued it in al-Muhadhdhab, saying: ‘This is a rejected hadith, and it is not known who Harun is!’” I say: This is one of al-Dhahabi’s errors. He thought that this Harun ibn Muslim was the one who narrated from Qatadah, and from whom Salam ibn Qutaybah and others narrated. Abu Hatim said of him: “He is unknown.” The same is stated in al-Mizan. Then, immediately after him, it mentions Harun ibn Muslim, the henna seller, and cites Abu Hatim’s aforementioned statement about him: “There is some weakness in him,” as well as al-Hakim’s statement: “Trustworthy.” Thus, he confused him with the one before him in al-Muhadhdhab, and the error arose from this.
