I said: This is a sound isnād; its narrators are trustworthy, the narrators of the two Shaykhs, except for ʿAbd al-Ghaffār ibn Dāwūd, who is among the narrators of al-Bukhārī.

"Do not revile Tubbaʿ, for he had embraced Islam." It is narrated from the ḥadīth of Sahl ibn Saʿd al-Sāʿidī, ʿAbd Allāh ibn ʿAbbās, and ʿĀʾishah as marfūʿ, and from Wahb ibn Munabbih as mursal. 1 - As for the ḥadīth of Sahl, it is narrated by Ibn Lahīʿah: Abū Zurʿah ʿAmr ibn Jābir narrated to us, I heard Sahl ibn Saʿd with it. It was recorded by Aḥmad (5/340), al-Ṭabarānī in "al-Awsaṭ" (p. 368 - Majmaʿ al-Baḥrayn) and (Q 8/2 - al-Muntaqá minhu), al-Rūyānī in "Musnad" (29/201/2), and Ibn ʿAsākir in "al-Tārīkh" (3/251/2 - Khaṭṭ 10/408 Ṭ), and al-Ṭabarānī said: "It is not narrated from Sahl ibn Saʿd except through this isnād, and Ibn Lahīʿah is unique in narrating it." I said: It is weak, and likewise his teacher ʿAmr ibn Jābir. 2 - As for the ḥadīth of Ibn ʿAbbās, it is narrated by Aḥmad ibn al-Qāsim ibn Abī Bazza: Muʾammal ibn Ismāʿīl informed us from Sufyān al-Thawrī from Simāk ibn Ḥarb from ʿIkrimah from Ibn ʿAbbās as marfūʿ. It was recorded by Abū Bakr ibn Khallād in "al-Fawāʾid" (1/217/1), and from him by Ibn ʿAsākir and al-Ṭabarānī in "al-Awsaṭ" as well as in "al-Kabīr" (3/135/2), and al-Khaṭīb in "al-Tārīkh" (3/205), and al-Ṭabarānī said: "It is not narrated from Sufyān except by Muʾammal, and Ibn Abī Bazza is unique in narrating it." I said: He is Aḥmad ibn Muḥammad ibn ʿAbd Allāh ibn Abī Bazza. He is weak in ḥadīth as Abū Ḥātim said. And al-ʿUqaylī said: "He connects the ḥadīths."
