Al-Kahf 18:67

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

18:65 — And they found a servant from among Our servants 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

18:66 — Moses said to him, "May I follow you on [the condition] that you teach me from what you have been taught of sound judgement?"

وَكَيْفَ تَصْبِرُ عَلَىٰ مَا لَمْ تُحِطْ بِهِۦ خُبْرًا

18:68 — And how can you have patience for what you do not encompass in knowledge?"

قَالَ سَتَجِدُنِىٓ إِن شَآءَ ٱللَّهُ صَابِرًا وَلَآ أَعْصِى لَكَ أَمْرًا

18:69 — [Moses] said, "You will find me, if Allah wills, patient, and I will not disobey you in [any] order."
