Al-Kahf - 18:88

وَأَمَّا مَنْ آمَنَ وَعَمِلَ صَالِحًا فَلَهُ جَزَاء الْحُسْنَى وَسَنَقُولُ لَهُ مِنْ أَمْرِنَا يُسْرًا
[18:88]
And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command.
"But whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command."
But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command.
