“The Messenger of Allah ﷺ entered the house and saw a piece of bread that had been thrown (on the floor). He picked it up, wiped it and ate it, and said: ‘O ‘Aishah, show honor to the precious (i.e., food), for is the blessing of food departs from people, it never comes back.’”
دَخَلَ النَّبِيُّ ﷺ الْبَيْتَ فَرَأَى كِسْرَةً مُلْقَاةً فَأَخَذَهَا فَمَسَحَهَا ثُمَّ أَكَلَهَا وَقَالَ يَا عَائِشَةُ أَكْرِمِي كَرِيمَكِ فَإِنَّهَا مَا نَفَرَتْ عَنْ قَوْمٍ قَطُّ فَعَادَتْ إِلَيْهِمْ
