On the authority of ʿUmar ibn Abī Salamah, who said: The Prophet ﷺ said: "Come near, my son, mention the name of Allah, eat with your right hand, and eat from what is before you."(1)

‌‌20. Chapter on Eating Meat

3778 - Saʿīd ibn Manṣūr narrated to us, Abū Maʿshar narrated to us, from Hishām ibn ʿUrwah, from his father, from ʿĀʾishah, who said: The Messenger of Allah ﷺ said: "Do not cut meat with the knife, for that is the practice of the foreigners, but tear it with your teeth, for that is more wholesome and more pleasant."(2)

--------------------------------------------
(1) Its chain of transmission is authentic. Abū Wajzah: he is Yazīd ibn ʿUbayd al-Saʿdī.
It was also narrated by al-Ṭayālisī (1358), and Ibn Ḥibbān in his "Ṣaḥīḥ" (5211) via two chains from Hishām ibn ʿUrwah, from Abū Wajzah, from ʿUmar ibn Abī Salamah.
It was also narrated by al-Nasāʾī in "al-Kubrā" (6723), (10035), and (10036) via multiple chains from Hishām ibn ʿUrwah, from Abū Wajzah, from a man of Muzaynah, from ʿUmar ibn Abī Salamah. Thus he added to the chain: a man of Muzaynah. However, Abū Wajzah's explicit statement that he heard it from ʿUmar ibn Abī Salamah occurs in Aḥmad (16339) and (16340), so the chain is connected. It is not unlikely that Abū Wajzah heard it in both ways, and Allah Most High knows best. Abū ʿUmar ibn ʿAbd al-Barr said in "al-Tamhīd" 23/17:
Abū Wajzah al-Saʿdī did hear this ḥadīth from ʿUmar ibn Abī Salamah.
It was also narrated by al-Nasāʾī in "al-Kubrā" (6722) and (10032–10034), and al-Tirmidhī (1963) via multiple chains from Hishām ibn ʿUrwah, from his father, from ʿUmar ibn Abī Salamah.
It was also narrated by Muslim (2022) and Ibn Mājah (3267) via the route of Wahb ibn Kaysān, from ʿUmar ibn Abī Salamah.
It is also in "Musnad Aḥmad" (16330), (16332), and (16334), and "Ṣaḥīḥ Ibn Ḥibbān" (5211) and (5215).

(2) Its chain of transmission is weak, as the author said. Abū Maʿshar—he is Nujayḥ ibn ʿAbd al-Raḥmān al-Sindī—is weak in ḥadīth, and al-Nasāʾī, following the ḥadīth (2243), counted this ḥadīth among his rejected narrations. =
