As for Muḥammad—who is Ibn al-Qāsim, as stated in an earlier hadith recorded by Ibn ʿAdī—I have not been able to identify him.
The hadith also has another route from Sālim, with a different wording. It has already preceded under no. 674. Al-Bazzār also transmitted it, and al-Haythamī referred to it after this text, saying (8/148):
“Al-Bazzār narrated it through two chains, the narrators of both of which are trustworthy.” *
3100—“Whoever attributes to me something I did not say, let him take his seat in the Fire.”
It has been narrated in these words from a number of the Companions, and I shall cite such routes from them as I have been able to locate that may be adduced as evidence or cited in corroboration.
The first: ʿUthmān, may Allah be pleased with him. It is narrated by ʿAbd al-Raḥmān ibn Abī al-Zinād, from his father, from ʿĀmir ibn Saʿd ibn Abī Waqqāṣ, who said: I heard ʿUthmān ibn ʿAffān, may Allah be pleased with him, say:
“What prevents me from narrating from the Messenger of Allah, peace and blessings be upon him, is not that I was any less retentive than his Companions regarding him. Yet I bear witness that I heard him say …” He then mentioned it.
It was recorded by al-Bukhārī in al-Tārīkh (3/2/209), al-Ṭaḥāwī in Mushkil al-Āthār (1/166), Aḥmad (1/65), and al-Bazzār (1/113/205).
I say: Its chain is good, owing to the well-known disagreement concerning ʿAbd al-Raḥmān ibn Abī al-Zinād. Shaykh Aḥmad Shākir, may Allah have mercy on him, graded it authentic in his commentary on al-Musnad (1/363).
The second: Abū Hurayrah, may Allah be pleased with him. It has several routes from him:
The first: from Muḥammad ibn ʿAmr, who said: Abū Salamah narrated to us, from Abū Hurayrah, from the Messenger of Allah, peace and blessings be upon him, who said … He then mentioned it.
It was recorded by Ibn Mājah (34) and Ibn Ḥibbān (no. 28—al-Iḥsān).
