Chapter 58 | The Meat of Cows and their Fat
عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ عَلِيِّ بْنِ حَسَّانَ عَنْ مُوسَى بْنِ بَكْرٍ قَالَ سَمِعْتُ أَبَا الْحَسَنِ ( عليه السلام ) يَقُولُ اللَّحْمُ يُنْبِتُ اللَّحْمَ وَ مَنْ أَدْخَلَ فِي جَوْفِهِ لُقْمَةَ شَحْمٍ أَخْرَجَتْ مِثْلَهَا مِنَ الدَّاءِ .
4. A number of our people have narrated from Sahl ibn Ziyad from Ali ibn Hassan from Musa ibn Bakr who has said the following: “I once heard abu al-Hassan , saying, ‘Meat grows meat, but if one sends a morsel of shahm (fat) inside it expels the same amount of illness out.’”
