Qur'an 18:88 · Al-Kahf

وَأَمَّا مَنْ ءَامَنَ وَعَمِلَ صَٰلِحًۭا فَلَهُۥ جَزَآءً ٱلْحُسْنَىٰ ۖ وَسَنَقُولُ لَهُۥ مِنْ أَمْرِنَا يُسْرًۭا

(88) But as for one who believes and does righteousness, he will have a reward of the best [i.e., Paradise], and we [i.e., Dhul-Qarnayn] will speak to him from our command with ease."
