Hadith 25113

Jabir reported that a person came to Allah's Apostle (ﷺ) and asked for food. And he gave him half a wasq of barley, and the person and his wife and their guests kept on making use of it (as a food) until he weighed it (in order to find out the actual quantity, and it was no more). He came to Allah's Apostle (ﷺ) (and informed him about it). He said:
Had you not weighed it, you would be eating out of it and it would have remained intact for you. (RU)
