I heard the Messenger of Allah ﷺ saying, "The human being does not fill any vessel that is worse than his stomach. It is sufficient for the son of Adam to eat what will support his back. If this is not possible, then a third for food, a third for drink, and third for his breath."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ: «مَا مَلَأَ ابْنُ آدَمَ وِعَاءً شَرًّا مِنْ بَطْنٍ: حَسْبُ ابْنِ آدَمَ أُكُلَاتٌ يُقِمْنَ صُلْبَهُ؛ فَإِنْ كَانَ لَا مَحَالَةَ فَثُلُثُ طَعَامٍ، وَثُلُثُ شَرَابٍ، وَثُلُثٌ لِنَفْسِهِ۔»  

I heard the Messenger of Allah ﷺ saying, "The human being does not fill any vessel that is worse than his stomach. It is sufficient for the son of Adam to eat what will support his back. If this is not possible, then a third for food, a third for drink, and third for his breath."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ: «مَا مَلأَ آدَمِيٌّ وِعَاءً شَرًّا مِنْ بَطْنٍ: بِحَسْبِ ابْنِ آدَمَ أُكُلاَتٌ يُقِمْنَ صُلْبَهُ؛ فَإِنْ كَانَ لاَ مَحَالَةَ، فَثُلُثٌ لِطَعَامِهِ، وَثُلُثٌ لِشَرَابِهِ، وَثُلُثٌ لِنَفَسِهِ۔»  

“I heard the Messenger of Allah ﷺ say: ‘A human being fills no worse vessel than his stomach. It is sufficient for a human being to eat a few mouthfuls to keep his spine straight. But if he must (fill it), then one third of food, one third for drink and one third for air.’”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَا مَلأَ آدَمِيٌّ وِعَاءً شَرًّا مِنْ بَطْنٍ حَسْبُ الآدَمِيِّ لُقَيْمَاتٌ يُقِمْنَ صُلْبَهُ فَإِنْ غَلَبَتِ الآدَمِيَّ نَفْسُهُ فَثُلُثٌ لِلطَّعَامِ وَثُلُثٌ لِلشَّرَابِ وَثُلُثٌ لِلنَّفَسِ
