From Sahih Muslim (Hadith 2483):
Juwayriya, the wife of the Messenger of Allah (ﷺ)" said that Messenger of Allah (ﷺ) came to her and said:Is there anything to eat? She said: Messenger of Allah, I swear by God, there is no food with us except a bone of goat which my freed maid-servant was given as sadaqa. Upon this he said: Bring that to me, for it (the sadaqa) has reached its destination
