Muḥammad ibn al-Qāsim al-Ṭāʾī was profiled by Ibn Abī Ḥātim (4/1/64–65), on the authority of another group of trustworthy narrators, but he did not mention any negative or positive evaluation of him. He meets Ibn Ḥibbān’s criteria for inclusion among the trustworthy narrators in his work, though I did not find him in its printed Indian edition or in the al-Ẓāhiriyyah manuscript either.
As for Salāmah ibn Jawwās, Ibn Abī Ḥātim said (2/1/302): “Abū Zurʿah and Muḥammad ibn ʿAwf al-Ḥimṣī narrated from him.” I say: He is therefore trustworthy, since Abū Zurʿah narrates only from a trustworthy narrator, as is well known. Moreover, he meets Ibn Ḥibbān’s criteria as well, and Ibn Ḥibbān included him among the trustworthy narrators (8/300).
Yaḥyā ibn Ṣāliḥ also corroborated him: “Muḥammad ibn al-Qāsim al-Ṭāʾī narrated to us,” with the same report. Al-Bazzār likewise transmitted it. Yaḥyā is trustworthy. Junādah ibn Marwān al-Raqqī also corroborated him: “Muḥammad ibn al-Qāsim al-Ṭāʾī narrated to us.” Al-Ḥākim likewise transmitted it, if it has been soundly preserved.
He was also corroborated by al-Walīd ibn Marwān ibn ʿAbd Allāh, the nephew of Junādah ibn Marwān: “Muḥammad ibn al-Qāsim, Abū al-Qāsim al-Ḥimṣī, related to me from ʿAbd Allāh ibn Busr”—and ʿAbd Allāh ibn Busr was his father’s partner in a village called Tamūnah (1), where they grazed horses belonging to them—“Abū al-Qāsim said: I heard ʿAbd Allāh ibn Busr say: ‘The Messenger of Allah, peace and blessings be upon him, came to our home with my father. My father rose to a rug with a sparse nap, gathered it in his hand, and then laid it down for the Prophet, peace and blessings be upon him, who sat upon it. Then my father said to my mother: “Do you have—”
