The Arabic word al-khadir means 'green'; the honorific name al-Khidr consequently means 'The Green One'. According to the Alexander Romance, after Khidr dove into the Water of Life — which he had found by using a shining jewel brought from Paradise by the prophet Adam — "all the flesh of his body became bluish-green and his garments likewise".
