The Cave
فَٱنطَلَقَا حَتَّىٰٓ إِذَا لَقِيَا غُلَـٰمًا فَقَتَلَهُۥ قَالَ أَقَتَلْتَ نَفْسًا زَكِيَّةًۢ بِغَيْرِ نَفْسٍ لَّقَدْ جِئْتَ شَيْـًٔا 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 أَقُلْ إِنَّكَ لَن تَسْتَطِيعَ مَعِىَ صَبْرًا
[Al-Khidh r] said, "Did I not say that with me you would never be able to have patience?"
قَالَ لَا تُؤَاخِذْنِى بِمَا نَسِيتُ وَلَا تُرْهِقْنِى مِنْ أَمْرِى عُسْرًا
[Moses] said, "Do not blame me for what I forgot and do not cover me in my matter with difficulty."
۞ قَالَ أَلَمْ أَقُل لَّكَ إِنَّكَ لَن تَسْتَطِيعَ مَعِىَ صَبْرًا
[Al-Khidh r] said, "Did I not tell you that with me you would never be able to have patience?"
قَالَ إِن سَأَلْتُكَ عَن شَىْءٍۭ بَعْدَهَا فَلَا تُصَـٰحِبْنِى ۖ قَدْ بَلَغْتَ مِن لَّدُنِّى عُذْرًا
[Moses] said, "If I should ask you about anything after this, then do not keep me as a companion. You have obtained from me an excuse."
