Kur’an 18:88 — sura Al-Kahf, 88. ajet

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

A onome ko bude vjerovao i dobra djela činio – nagrada najljepša, i s njim ćemo blago postupiti."

But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease
