Translation of Surah Al-Kahf, ayah 74 (18:74)

فَٱنطَلَقَا حَتَّىٰٓ إِذَا لَقِيَا غُلَٰمٗا فَقَتَلَهُۥ قَالَ أَقَتَلۡتَ نَفۡسٗا زَكِيَّةَۢ بِغَيۡرِ نَفۡسٖ لَّقَدۡ جِئۡتَ شَيۡـٔٗا نُّكۡرٗا ٧٤
So they proceeded until they came across a boy, and the man killed him. Moses protested, “Have you killed an innocent soul, who killed no one? You have certainly done a horrible thing.”
