18:74
فَٱنطَلَقَا حَتَّىٰٓ إِذَا لَقِيَا غُلَـٰمًا فَقَتَلَهُۥ قَالَ أَقَتَلْتَ نَفْسًا زَكِيَّةًۢ بِغَيْرِ نَفْسٍ لَّقَدْ جِئْتَ شَيْـًٔا نُّكْرًا

Then they both proceeded, till they met a boy, he (Khidr) killed him. Musa (Moses) said: "Have you killed an innocent person who had killed none? Verily, you have committed a thing "Nukra" (a great Munkar - prohibited, evil, dreadful thing)!" - Muhammad Taqi-ud-Din al-Hilali and Muhammad Muhsin Khan (English)
