آداب الطعام

The Prophet ﷺ taught a boy: "Say Bismillah, eat with your right hand, and eat from what is near you" (Bukhari 5376, Muslim 2022).

So at the table: wash your hands, say Bismillah, eat with your right hand, take small bites, do not waste food, and say Alhamdulillah at the end.

We do not complain about food. If we do not like something, we say "no thank you" politely.
