“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.’” (Using translation from Ibn Mājah 3349)

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَا مَلَأَ آدَمِيٌّ وِعَاءً شَرًّا مِنْ بَطْنٍ حَسْبُ الْآدَمِيِّ لُقْمَاتٌ يُقِمْنَ صُلْبَهُ فَإِنْ غَلَبَتْهُ نَفْسُهُ» ثُمَّ ذَكَرَ كَلِمَةً مَعْنَاهَا فَثُلُثٌ طَعَامٌ وَثُلُثٌ شَرَابٌ وَثُلُثٌ لِلنَّفَسِ خَالَفَهُ بَقِيَّةُ بْنُ الْوَلِيدِ

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."

عَنِ النَّبِيِّ ﷺ قَالَ «مَا مَلَأَ آدَمِيٌّ وِعَاءً شَرًّا مِنْ بَطْنٍ حَسْبُ ابْنِ آدَمَ لُقْمَاتٌ يُقِمْنَ صُلْبَهُ فَإِنْ غَلَبَتْهُ نَفْسُهُ فَثُلُثٌ طَعَامٌ وَثُلُثٌ شَرَابٌ وَثُلُثٌ لِلنَّفَسِ»

that the Prophet ﷺ said: “No vessel is worse than the stomach. It is sufficient for a Muslim to have a few bites that keep his back upright. But if he must, then a third for his food, a third for his drink, and a third for his breath.”

أَنَّ النَّبِيَّ ﷺ قَالَ: «مَا وِعَاءٌ شَرَّ مِنْ بَطْنٍ: حَسْبُ الْمُسْلِمِ أُكُلَاتٌ يُقِمْنَ صُلْبَهُ. فَإِنْ كَانَ لَا مَحَالَةَ، فَثُلُثٌ لِطَعَامِهِ وَثُلُثٌ لِشَرَابِهِ وَثُلُثٌ لِنَفَسِهِ».
