Hadith 31-130

وَبِهذَا الإِسنادِ عَنْ عَلِىِّ بْنِ أَبِي طالِبٍ‏ عَلَيْهِ السَّلامُ قالَ: ذُكِرَ عِنْدَ النَّبِيِ‏ صَلَّى اللهُ عَلَيْهِ وَآلِهِ اللَّحْمُ وَالشَّحمُ فَقالَ: لَيْسَ مِنْهُما بَضعَةٌ تَقَعُ فِي المِعدَةِ إِلّا أَنبَتَت مَكانَها شِفاءً وَأَخرَجَت مِن مَكانَها داءً.

According to the same documentation, Ali ibn Abi Talib (a.s.) said, “There was talk of meat and fat in the presence of the Prophet (S). He (a.s.) said, “Whenever a bite of meat or fat enters the stomach, it will heal there and remove the pains from there.”
