(Qasas) 28 : 14
وَلَمَّا بَلَغَ أَشُدَّهُ وَاسْتَوَىٰ آتَيْنَاهُ حُكْمًا وَعِلْمًا ۚ وَكَذَٰلِكَ نَجْزِي الْمُحْسِنِينَ

And when he attained his full strength and was matured, We bestowed upon him Wisdom and Knowledge; and thus do We reward the Muhsins.

Muhsins are those who live under the Light of Adhikr as explained in verse 12: 22. It is told in verse 37: 80: “Indeed, thus We do reward the Muhsins”. See explanation 13: 18.
