لَيْسَ الْمُؤْمِنُ بِالَّذِي يَشْبَعُ وَجَارُهُ جَائِعٌ إِلَى جَنْبِهِ
It is not fitting for a believer to eat his fill while his neighbor beside him remains hungry.

لَيْسَ الْمُؤْمِنُ بِالَّذِي ... rejects conduct unfitting for a believer. يَشْبَعُ means “he eats his fill,” جَارُهُ means “his neighbor,” and جَائِعٌ means “hungry.” The clause وَجَارُهُ جَائِعٌ creates a direct contrast between two conditions.
Eating enough is not itself condemned. The warning concerns indifference when a nearby neighbor lacks food. If one becomes aware of the need, dignified assistance, sharing a meal, or arranging suitable support within one's means reflects genuine concern.
