who marries them and exiles her younger daughter to the stables. Later, war breaks out with a neighbouring king, and the prince summons the flying mare to ride into battle and defeat his father-in-law's enemies. During the fight, his hand is injured, and the Sultan bandages him with a piece of a shawl. Their victory assured, the prince goes back to the gardener and to his lowly disguise. The Sultan returns to Baghdad and inquires if anyone has seen the fine and mysterious warrior, but none can give any answer. Distraught with grief over not finding the warrior, the Sultan falls ill and becomes blind, and the royal doctors prescribe lioness's milk served inside a lion's skin.
