Al-Kahf 18:67

قَالَ ذَٰلِكَ مَا كُنَّا نَبْغِ ۚ فَارْتَدَّا عَلَىٰ آثَارِهِمَا قَصَصًا

[Moses] said, "That is what we were seeking." So they returned, following their footprints.

فَوَجَدَا عَبْدًا مِّنْ عِبَادِنَا آتَيْنَاهُ رَحْمَةً مِّنْ عِندِنَا وَعَلَّمْنَاهُ مِن لَّدُنَّا عِلْمًا

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 لَهُ مُوسَىٰ هَلْ أَتَّبِعُكَ عَلَىٰ 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?"

وَكَيْفَ تَصْبِرُ عَلَىٰ مَا لَمْ تُحِطْ بِهِ خُبْرًا

And how can you have patience for what you do not encompass in knowledge?"

قَالَ سَتَجِدُنِي إِن شَاءَ اللَّهُ صَابِرًا وَلَا أَعْصِي لَكَ أَمْرًا

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

قَالَ فَإِنِ اتَّبَعْتَنِي فَلَا تَسْأَلْنِي عَن شَيْءٍ حَتَّىٰ أُحْدِثَ لَكَ مِنْهُ ذِكْرًا

He said, "Then if you follow me, do not ask me about anything until I make to you about it mention."
