Surah Al-Kahf Ayahs #76 Translated in English

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

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

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

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

[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."
