وَأَمَّا حَقُّ بَطْنِكَ فَأَنْ لا تَجْعَلَهُ وِعَاءً لِقَلِيلٍ مِنَ الْحَرَامِ وَلا لِكَثِيرٍ، وَأَنْ تَقْتَصِدَ لَهُ فِي الْحَلالِ وَلا تُخرِجَهُ مِنْ حَدِّ التَّقْوِيَةِ إلَى حَدِّ التَّهْوِينِ وَذَهَاب الْمُرُوَّةِ، وَضَبْطُهُ إذَا هَمَّ بالْجُوعِ والظمأ فَإنَّ الشَّبْعَ الْمُنْتَهِي بصَاحِبهِ إلَى التُّخمِ مَكْسَلَةٌ وَمَثْبَطَةٌ وَمَقْطَعَةٌ عَنْ كُلِّ برِّ وَكَرَمٍ. وَإنَّ الري الْمُنْتَهِي بصَاحِبهِ إلَى السُّكْرِ مَسْخَفَةٌ

وَمَجْهَلَةٌ وَمَذْهَبَةٌ لِلْمُرُوَّةِ


And the right of your stomach is that you make it not into a container for a little of that which is unlawful to you or a lot of it. You should be determined to eat what is lawful and not exceed the bounds of strengthening to the extent of belittling your stomach to the point that you loose your manliness. And you should restrain it whenever you are extremely hungry or thirsty, since getting really full will cause indigestion, sluggishness, indolence, and it will hinder you from nobility and any good deeds. And drinking too much will make you feel drunk, light-headed, ignorant, and take away your manliness.
