Al-Kahf 18:71

<h2>Damaging the Boat</h2><p>Allah tells us that Musa and his companion Al-Khidr set out having come to an agreement and reached an understanding. Al-Khidr had made the condition that Musa should not ask him about anything he found distasteful until he himself initiated the discussion and offered an explanation. So they went on board the ship, as described in the Hadith quoted above -- the crew recognized Al-Khidr and let them ride on board free of charge, as an honor to Al-Khidr. When the boat took them out to sea and they were far from the shore, Al-Khidr got up and damaged the boat, pulling out one of its planks and then patching it up again. Musa, peace be upon him, could not restrain himself from denouncing him, so he said:</p><p>أَخَرَقْتَهَا لِتُغْرِقَ أَهْلَهَا</p><p>(Have you damaged it wherein its people will drown) The grammatical structure of the sentence in Arabic implies that this was the consequence, not the purpose, of his action.</p><p>لَقَدْ جِئْتَ شَيْئًا إِمْرًا</p><p>(Verily, you have committed a thing Imr.)

So they both proceeded: until, when they were in the boat, he scuttled it. Said Moses: "Hast thou scuttled it in order to drown those in it? Truly a strange thing hast thou done!"

So they both proceeded, till, when they embarked the ship, he (Khidr) scuttled it. Musa (Moses) said: "Have you scuttled it in order to drown its people? Verily, you have committed a thing "Imra" (a Munkar - evil, bad, dreadful thing)."

So they set out. Until, when they had boarded the boat, he holed it. He said, “Did you hole it, to drown its passengers? You have done something awful.”
