مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ سِنَانٍ عَنْ صَالِحٍ النِّيلِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ إِنَّ اللَّهَ عَزَّ وَ جَلَّ يُبْغِضُ كَثْرَةَ الْأَكْلِ وَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) لَيْسَ لِابْنِ آدَمَ بُدٌّ مِنْ أَكْلَةٍ يُقِيمُ بِهَا صُلْبَهُ فَإِذَا أَكَلَ أَحَدُكُمْ طَعَاماً فَلْيَجْعَلْ ثُلُثَ بَطْنِهِ لِلطَّعَامِ وَ ثُلُثَ بَطْنِهِ لِلشَّرَابِ وَ ثُلُثَ بَطْنِهِ لِلنَّفَسِ وَ لَا تَسَمَّنُوا تَسَمُّنَ الْخَنَازِيرِ لِلذَّبْحِ .
9. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Sinan from Salih al-Niliy who has said the following: “Abu ’Abd Allah , has said, ‘Allah, most Majestic, most Glorious, hates overeating.’ Abu ‘Abd Allah , has said, ‘Children of Adam must eat to keep their backs straight. When one of you eats keep one-third of your stomach for food one-third for water and one-third for breathing and never become fat like pigs to be slaughtered.’”
