Surah Ali 'Imran — Ayah 115 (3:115)
وَمَا يَفۡعَلُواْ مِنۡ خَيۡرٖ فَلَن يُكۡفَرُوهُۗ وَٱللَّهُ عَلِيمُۢ بِٱلۡمُتَّقِينَ ١١٥
English translation (Saheeh International)
And whatever good they do - never will it be denied them. And Allāh is Knowing of the righteous.
Brief commentary
Whatever good these people do, whether it is little or much, their reward for it will not be lost. Allah knows those who are Mindful, who follow what He instructs, and stay away from what He prohibits. None of what they do is hidden from Him, and they will be rewarded accordingly.
