Abu Hurairah narrated that the Prophet(s.a.w) said: "The one who eats and is grateful is like the status of the patient fasting person".
The Prophet(s.a.w) was teaching us here about the power of gratitude and how it can bring great rewards from Allah even when we are doing something seemingly mundane like eating food or drinking water - if done with an attitude of thankfulness then it will be rewarded greatly by Allah in both this world and the hereafter!
This hadith also serves as a reminder to us that no matter what situation we find ourselves in - whether good or bad - there is always something to be thankful for! We should never forget to express our thanks and appreciation to Allah for all His blessings upon us no matter how small they may seem at times!
