فَوَجَدَا عَبْدًا مِّنْ عِبَادِنَآ ءَاتَيْنَـٰهُ رَحْمَةً مِّنْ عِندِنَا وَعَلَّمْنَـٰهُ مِن لَّدُنَّا عِلْمًا

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.

قَالَ لَهُۥ مُوسَىٰ هَلْ أَتَّبِعُكَ عَلَىٰٓ أَن تُعَلِّمَنِ مِمَّا عُلِّمْتَ رُشْدًا

Moses said to him, "May I follow you on [the condition] that you teach me from what you have been taught of sound judgement?"
