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. (Using translation from Tirmidhī 1832)
" إذَا اشْترى أحدُكم لحمًا فليُكثر مَرَقته، فإنْ لم يُصبْ أحدُكم لحمًا أصابَ مرقًا، وهو أحدُ اللَّحْمين" .
