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)  

أَنَّهُ مَشَى إِلَى النَّبِيِّ ﷺ بِخُبْزِ شَعِيرٍ وَإِهَالَةٍ سَنِخَةٍ وَلَقَدْ رَهَنَ النَّبِيُّ ﷺ دِرْعًا لَهُ بِالْمَدِينَةِ عِنْدَ يَهُودِيٍّ وَأَخَذَ مِنْهُ شَعِيرًا لأَهْلِهِ وَلَقَدْ سَمِعْتُهُ يَقُولُ مَا أَمْسَى عِنْدَ آلِ مُحَمَّدٍ ﷺ صَاعُ بُرٍّ وَلاَ صَاعُ حَبٍّ وَإِنَّ عِنْدَهُ لَتِسْعَ نِسْوَةٍ  

I walked to the Prophet ﷺ with some barley bread that has some rancid oil poured over it. The Prophet ﷺ had pawned his armour with a Jew for twenty Sa' of food that he got for his family. That day (he pawned it), I heard him saying: 'Not for one evening has the household of Muhammad had a Sa' of dates or a Sa' of grain.' And on that day he had nine wives."  

مَشَيْتُ إِلَى النَّبِيِّ ﷺ بِخُبْزِ شَعِيرٍ وَإِهَالَةٍ سَنِخَةٍ وَلَقَدْ رُهِنَ لَهُ دِرْعٌ عِنْدَ يَهُودِيٍّ بِعِشْرِينَ صَاعًا مِنْ طَعَامٍ أَخَذَهُ لأَهْلِهِ وَلَقَدْ سَمِعْتُهُ ذَاتَ يَوْمٍ يَقُولُ مَا أَمْسَى فِي آلِ مُحَمَّدٍ ﷺ صَاعُ تَمْرٍ وَلاَ صَاعُ حَبٍّ وَإِنَّ عِنْدَهُ يَوْمَئِذٍ لَتِسْعُ نِسْوَةٍ  

[Machine] I went to the Prophet with a bread made from barley and a piece of meat. He had pawned his armor for barley. I heard him saying, "Neither the family of Muhammad nor I have had their fill of food in the morning or evening, except for a small amount. On that day, they will be nine in number."  

مَشَيْتُ إِلَى النَّبِيِّ ﷺ بِخُبْزِ شَعِيرٍ وَإِهَالَةٍ سَنِخَةٍ وَلَقَدْ رَهَنَ دِرْعَهُ بِشَعِيرٍ وَلَقَدْ سَمِعْتُهُ يَقُولُ مَا أَصْبَحَ لِآلِ مُحَمَّدٍ وَلَا أَمْسَى إِلَّا صَاعٌ وَإِنَّهُمْ يَوْمَئِذٍ تِسْعَةُ أَبْيَاتٍ
