I said: and the wording of the addition according to him is: "and with it are nine-tenths of disbelief and with it is the chronic disease." perhaps he means by uniqueness this addition, otherwise the ḥadīth with the first addition has been corroborated by Abū ʿAbd al-Raḥmān - who is ʿAbd Allāh ibn Yazīd - with Aḥmad and Ibn ʿAsākir, and its men are trustworthy, the men of the two Shaykhs, except for ʿAbd al-Raḥmān ibn ʿAṭāʾ, who is trustworthy but has some weakness, as indicated by the statement of the ḥāfiẓ in "Taqrīb": "truthful, but has some leniency." so I have a pause regarding the authenticity of this addition, due to ʿAbd al-Raḥmān's uniqueness in it without other narrators, especially since it was narrated by al-Fasawī (2/750 and 751) from Ibn Masʿūd and ʿAlī (raḍiya Allāhu ʿanhumā) as mawqūf, and it does not appear to me to be in the ruling of marfūʿ. And Allāh knows best. and he was followed by Abū ʿUbayd Ḥājib Sulaymān ibn ʿAbd al-Malik from Nāfiʿ with it, except that he said: "Iraq and Egypt." It was produced by Abū ʿAbd Allāh al-Qaṭṭān in "His Ḥadīth" (Q 59/2), and Abū Umayyah al-Ṭarsūsī in "Musnad Ibn ʿUmar" (Q 207/1-2), and Ibn ʿAsākir (1/124-125) through the route of Muḥammad ibn Yazīd ibn Sanān al-Rahāwī from his father: Abū Razīn al-Filasṭīnī narrated it from him. I said: and this isnād is weak, Abū ʿUbayd is trustworthy, but Abū Razīn, the narrator from him, I did not know him, and al-Dhahabī mentioned him in "al-Muqtaṣá fī al-Kuná" with this narration, and he did not name him. And al-Rahāwī is not strong, as the ḥāfiẓ said, so the mention of "Egypt" in this route is objectionable. And with Allāh is success. and it has a corroborating narration, narrated by Isḥāq ibn ʿAbd Allāh ibn Kaysān from his father from Saʿīd ibn Jubayr from Ibn ʿAbbās as marfūʿ similar to the ḥadīth of the chapter. It was produced by al-Ṭabarānī in "al-Kabīr" (12/84/12553)
