Aal-'Imran - 3:115

وَمَا يَفْعَلُواْ مِنْ خَيْرٍ فَلَن يُكْفَرُوْهُ وَاللّهُ عَلِيمٌ بِالْمُتَّقِينَ
[3:115]
And whatever good they do, they shall not be denied it, and Allah knows those who guard (against evil).
Of the good that they do, nothing will be rejected of them; for Allah knoweth well those that do right.
And whatever good they do, they will not be denied the meed thereof. Allah is Aware of those who ward off (evil).
