If you are about to eat and the food is hot, it is encouraged to wait for the meal to cool down before eating it. This will prevent you from burning your tongue or mouth and from eating in a hasty manner. You will also enjoy the food better.
- Jabir Bin Abdullah  and Asma  narrate that the Prophet of Allah  said "Cool your meal because there is no blessing in hot food."
[Rawahul-Hakim and Abu Dawood]
