(18:72) [Al-Khidh r] said, "Did I not say that with me you would never be able to have patience?" (18:73) [Moses] said, "Do not blame me for what I forgot and do not cover me in my matter with difficulty." (18:74) 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." (18:75) [Al-Khidh r] said, "Did I not tell you that with me you would never be able to have patience?" (18:76) [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." (18:77) So they set out, until when they came to the people of a town, they asked its people for food, but they refused to offer them hospitality. And they found therein a wall about to collapse, so al-Khidh r restored it. [Moses] said, "If you wished, you could have taken for it a payment." (18:78) [Al-Khidh r] said, "This is parting between me and you. I will inform you of the interpretation of that about which you could not have patience.
