From his father, who said that the Prophet ﷺ said: "When one of you buys meat, then let him increase its broth. For, if he does not find any meat you'll have broth; and it is one of the two meats." And there are narrations on this topic from Abu Dharr.
قَالَ النَّبِيُّ ﷺ إِذَا اشْتَرَى أَحَدُكُمْ لَحْمًا فَلْيُكْثِرْ مَرَقَتَهُ فَإِنْ لَمْ يَجِدْ لَحْمًا أَصَابَ مَرَقَةً وَهُوَ أَحَدُ اللَّحْمَيْنِ وَفِي الْبَابِ عَنْ أَبِي ذَرٍّ
