Al-Kahf 18:72

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."

فَانطَلَقَا حَتَّىٰ إِذَا رَكِبَا فِي السَّفِينَةِ خَرَقَهَا ۖ قَالَ أَخَرَقْتَهَا لِتُغْرِقَ أَهْلَهَا لَقَدْ جِئْتَ شَيْئًا إِمْرًا

So they set out, until when they had embarked on the ship, al-Khidh r tore it open. [Moses] said, "Have you torn it open to drown its people? You have certainly done a grave thing."

قَالَ لَا تُؤَاخِذْنِي بِمَا نَسِيتُ وَلَا تُرْهِقْنِي مِنْ أَمْرِي عُسْرًا

[Moses] said, "Do not blame me for what I forgot and do not cover me in my matter with difficulty."

فَانطَلَقَا حَتَّىٰ إِذَا لَقِيَا غُلَامًا فَقَتَلَهُ قَالَ أَقَتَلْتَ نَفْسًا زَكِيَّةً بِغَيْرِ نَفْسٍ لَّقَدْ جِئْتَ شَيْئًا نُّكْرًا

So they set out, until when they met a boy, al-Khidh r killed him. [Moses] said, "Have you killed a pure soul for other than [having killed] a soul? You have certainly done a deplorable thing."

قَالَ أَلَمْ أَقُل لَّكَ إِنَّكَ لَن تَسْتَطِيعَ مَعِيَ صَبْرًا

[Al-Khidh r] said, "Did I not tell you that with me you would never be able to have patience?"
