Al-Kahf 18:64

فَلَمَّا بَلَغَا مَجْمَعَ بَيْنِهِمَا نَسِيَا حُوتَهُمَا فَاتَّخَذَ سَبِيلَهُ فِي الْبَحْرِ سَرَبًا

But when they reached the junction between them, they forgot their fish, and it took its course into the sea, slipping away.

فَلَمَّا جَاوَزَا قَالَ لِفَتَاهُ آتِنَا غَدَاءَنَا لَقَدْ لَقِينَا مِن سَفَرِنَا هَـٰذَا نَصَبًا

So when they had passed beyond it, [Moses] said to his boy, "Bring us our morning meal. We have certainly suffered in this, our journey, [much] fatigue."

قَالَ أَرَأَيْتَ إِذْ أَوَيْنَا إِلَى الصَّخْرَةِ فَإِنِّي نَسِيتُ الْحُوتَ وَمَا أَنسَانِيهُ إِلَّا الشَّيْطَانُ أَنْ أَذْكُرَهُ ۚ وَاتَّخَذَ سَبِيلَهُ فِي الْبَحْرِ عَجَبًا

He said, "Did you see when we retired to the rock? Indeed, I forgot [there] the fish. And none made me forget it except Satan - that I should mention it. And it took its course into the sea amazingly".

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?"

قَالَ إِنَّكَ لَن تَسْتَطِيعَ مَعِيَ صَبْرًا

He said, "Indeed, with me you will never be able to have patience.
