Abu Juhaifah Wahb bin 'Abdullah (May Allah be pleased with him) reported: Messenger of Allah ﷺ said, "I do not eat reclining (against a pillow)". Al-Bukhari.
The Prophet Muhammad (peace be upon him) also taught us to show respect for food by not wasting it or taking too much of it at once. We should take only what is necessary and leave some for others who may need it more than ourselves. By following these teachings, we can learn how to properly appreciate the food that Allah has given us and use it in a way that shows respect for both ourselves and those around us.
