his biography (15/164-165) with the isnād mentioned above! And he attributed it to Muslim! I have also seen it in "Musnad al-Sarāj" (Q 43/1) with this isnād, but it appeared as "ʿUbayd Allāh" in diminutive form! It is a good copy, and likewise, it is in his printed "Musnad" (1/328/314), but I believe it is a scribe's error because in the original manuscript it appears as: "ʿAbd" with a single tooth for the bāʾ between the ʿayn and dāl, and next to the point of the bāʾ, there appeared a smudge in the image that looked like another point to the left of the first, and below it and slightly larger, the verifier mistakenly thought it was two points! If it were correct, the original scribe would have also made a tooth for it like this "ʿUbayd," and the error is supported by the fact that in "Musnad Ibn Rāhwayh" before and after this, there are two other ḥadīths with different isnāds from this ʿAbd Allāh from his uncle Yazīd ibn al-Aṣam. But one of them—concerning the blind man's obligation to attend congregational prayer if he hears the call—is in "Ṣaḥīḥ Muslim" (2/124) through the route of Isḥāq and others, and in it: "ʿUbayd Allāh" in diminutive form! Likewise, it appeared in "Abū ʿAwānah" (2/7) through another route from the teacher of Isḥāq, Marwān ibn Muʿāwiyah al-Fazārī, from him. In summary, there is significant disagreement regarding the narrator of these ḥadīths, including the ḥadīth of the biography from Yazīd ibn al-Aṣam, to the extent that it suggests the possibility that it is one person whose name the narrators differed on, some enlarging it, and some diminishing it. Regardless of whether it is this or that, the important thing is that he is trustworthy among the men of Muslim, and those previously mentioned have authenticated it, especially since it has many supporting evidences, and although most are mursal, Ibn Jarīr extracted it in his "Tafsīr" (4/60) from the ḥadīth of ʿUmar ibn al-Khaṭṭāb and Ibn ʿAbbās, with two authentic isnāds from them—it indicates that this response from him (ṣallá Allāhu ʿalayhi wa-sallam) was known to them, as it has been narrated..
