Hadith About Food/Eating Manners

Sayyiduna Umar bin Abi Salimah (Radiyallahu Anhu) says: As a child, I used to eat With Rasulullah (Sallallahu Alaihi Wasallam) and I used to start eating from anywhere from my plate. Nabi (Sallallahu Alaihi Wasallam) advised me: “Oh little boy, take the name of Allah, eat with your right hand and eat from the end that is closer to you”
[Sahih Muslim, Hadith 5388]

Ibn Umar reported that Allah's Messenger (may peace be upon him) said: When any one of you is invited to a feast, he should attend it.
