Ya Musa, I want to hit you where your blood hasn't reached; a river pain, a rock pain. Strike you so your blood springs towards things like another heart; you who're stranger to my word.

Al Khidr says nothing. It's Musa who believes his lesson music.
He saw no grounding in his lesson, so he called it unfounded.
He found his lesson unfounded, so he dubbed it music.
