Surah Al-Kahf, ayah 88

18:88

وَأَمَّا مَنۡ ءَامَنَ وَعَمِلَ صَٰلِحٗا فَلَهُۥ جَزَآءً ٱلۡحُسۡنَىٰۖ وَسَنَقُولُ لَهُۥ مِنۡ أَمۡرِنَا يُسۡرٗا ٨٨

Wa ammā man āmana wa'amila sālihan falahū jazā'anil-husnā wasanaqūlu lahū min amrinā yusrā

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."
