Although the Prophet’s light is the most powerful in the universe, since he is the nearest created being to Allah, it is not the only one. Angels are made of light, the Qur’an is light, the spirits of human beings are light, faith is light, knowledge is light, the sun, the moon, and the stars are also lights. The light of each human being depends upon his faith, knowledge, and virtue. Thus the most powerful lights are those of Divine Messengers, then those of Prophets, saints, virtuous believers, and finally those of sinful believers. This is the hierarchy of human beings. Both the first and the last are human, all have lights, and all are slaves of Allah, but the distance between the top of the pyramid and its bottom is so great that those at the bottom, in Paradise, will see those at the top as distant as, in this world, we see the stars at night.[34. Tirmidhi.]
