لَا تُصَاحِبْ إِلَّا مُؤْمِنًا، وَلَا يَأْكُلْ طَعَامَكَ إِلَّا تَقِيٌّ
Keep close company with a believer, and let only a God-fearing person eat your (invitation) food.

لَا تُصَاحِبْ means “do not keep close company.” لَا is prohibitive and تُصَاحِبْ is a present-tense verb in the jussive form. إِلَّا means “except,” while تَقِيٌّ describes someone mindful of Allah who avoids wrong.
Close friends shape habits and values, so wise choice of intimate company matters. The second clause concerns invitation meals and close association; it does not forbid feeding hungry or needy people, including those outside one’s faith. The setting distinguishes invitation food from food offered to meet urgent need.
