"al-Haythamī said (1/283): "It was narrated by al-Ṭabarānī in "al-Kabīr", and its men are trustworthy." This is what he said, but as for the ḥāfiẓ, he said in "al-Talkhīṣ" (4/618): "And its isnād is weak." I said: in any case, the ḥadīth gives strength, and perhaps for this reason Shaykh al-Islām Ibn Taymiyyah (may Allāh have mercy on him) affirmed its attribution to the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) in "al-Fatāwá" (1/44)... Then the compilation in which this ḥadīth is found was published, and I saw it in (19/14/20) from the route of Qatādah ibn al-Faḍl ibn Qatādah al-Rahāwī from his father: My uncle Abū Hāshim ibn Qatādah al-Rahāwī narrated to me from his father. It became clear to me the correctness of the ḥāfiẓ's weakening of its isnād, and the error of his teacher al-Haythamī in declaring its men trustworthy, because his basis for that was Ibn Ḥibbān, who included both (Hāshim ibn Qatādah al-Rahāwī) and (al-Faḍl ibn Qatādah al-Rahāwī) in "Thiqāt" (5/503) and (7/317), and it is known that Ibn Ḥibbān is lenient in authentication, especially since the two men are only known through this isnād, and it has another ḥadīth which I had extracted in "al-Ḍaʿīfah" (5941) for being devoid of a corroborating witness, unlike this one, as it has the witness of the ḥadīth of the chapter. And it has a very brief witness in circumcision from the narration of al-Zuhrī who said: The Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said: "Whoever accepts Islam should circumcise, even if he is old." It was narrated by Ḥarb ibn Ismāʿīl as the ḥāfiẓ said in "al-Talkhīṣ" (4/82/1806 - commentary by al-Yamānī al-Madanī) and al-Suyūṭī attributed it in "al-Durr al-Manthūr" (1/114) to al-Bayhaqī, he mentioned it without specification, which means "al-Sunan al-Kubrā" of his, and I did not see it in it, and he went far afield, for Imām al-Bukhārī narrated it in "al-Adab al-Mufrad" (322/1252): ʿAbd al-ʿAzīz ibn ʿAbd Allāh al-Awaysī narrated to us saying: Sulaymān ibn Bilāl narrated to me from Yūnus from Ibn Shihāb who said:
