The Quran first mentions an 'inner meaning' ("ta'wil") in in the story of Moses and Khidr, a mystical figure of the ancient Middle East who reluctantly accepts Moses as his traveling student. When Khidr performs strange acts, Moses questions him about them. Khidr gives him the 'inner explanation' ("ta'wil") of his actions. Along the way, the esoteric being damages a boat belonging to poor people. Moses is so disturbed that he keeps protesting despite his agreement to keep silent. At the end of the journey, Khidr tells Moses the reasons for his inexplicable actions: "As for the ship, it belonged to poor people working at sea, so I intended to cause defect in it as there was after them a king who seized every ship by force."
