Al-Kahf 18:65

Fawajada AAabdan min AAibadinaataynahu rahmatan min AAindinawaAAallamnahu min ladunna AAilma

And they found a servant from among Our servants [i.e., al-Khiḍr] to whom We had given mercy from Us and had taught him from Us a [certain] knowledge.

Then they found one of Our servants whom We blessed with mercy from Us and whom We gave knowledge, a knowledge from Our own.
