Al-Insan 76:9
إِنَّمَا نُطْعِمُكُمْ لِوَجْهِ ٱللَّهِ لَا نُرِيدُ مِنكُمْ جَزَآءً وَلَا شُكُورًا
Innama nutAAimukum liwajhi Allahila nureedu minkum jazaan wala shukoora
"[Saying], "We feed you only for the face [i.e., approval] of Allāh. We wish not from you reward or gratitude."
Al-Insan 76:9, translation by Sahih International
A short reflection
We feed you only for the face of Allah. We desire from you neither reward nor thanks.
