Al-Kahf (The Cave)

Surah 18 · Verse 74

Then they proceeded until when they met a young man and he killed him. He (Musa) said, “Have you killed an innocent person without (this murder being in retaliation to his unjustly killing some other) person ? You have indeed come with something unrecognised.” (P 15)

فَانْطَلَقَا حَتَّىٰ إِذَا لَقِيَا غُلَامًا فَقَتَلَهُ قَالَ أَقَتَلْتَ نَفْسًا زَكِيَّةً بِغَيْرِ نَفْسٍ لَقَدْ جِئْتَ شَيْئًا نُكْرًا
