This hadith tells us to pick up a fallen dry morsel of food and eat it after brushing off any dirt that might be on it. This is an expression of humility and also prevents Shaitaan from deriving blessings from our food.
Present-day Muslims hardly care for this directive of the Messenger of Allah (sal Allahu alaihi wa sallam) thinking that picking up dropped food will bring disgrace and dishonour upon them. To make matters worse, some even throw away unconsumed food in the garbage, while others deem it necessary to leave a little food in their plates as a sign of their manners or affluence! How far the Muslim community has departed from the teachings and excellent example of their Prophet (sal Allahu alaihi wa sallam)!
