“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
