Sahih al-Bukhari Book 34, Hadith 23

family will eat from the National Treasury of Muslims, and I will practice the profession of serving
the Muslims."
Anas went to the Prophet (ﷺ) with barley bread having some dissolved fat on it. The Prophet (ﷺ) had mortgaged his armor to a Jew in Medina and took from him some barley for his family. Anas heard him saying, "The household of Muhammad did not possess even a single Sa of wheat or food grains for the evening meal, although he has nine wives to look after." (See Hadith No. 685)
