For this very reason (1) Allah sent His messengers, “so that they might bring mankind” (2) out of darkness into light. Whoever responds to them emerges into spaciousness, brightness, and radiance; whereas whoever refuses remains confined to the constriction and gloom in which he was created—namely, the darkness of innate disposition, the darkness of ignorance, the darkness of passion, and the darkness of heedlessness toward his own soul, its perfection, and the means to its happiness in this life and the next.
All of these (3) are layers of darkness in which the servant is born, so Allah dispatched His messengers to draw him out of them into the light (4) of knowledge, understanding, faith, and guidance, without which the soul can never find true happiness. Whoever is denied this light is denied his portion, his completeness, and his felicity, and he comes to flounder amid darknesses, one upon another: his entrance is darkness, his exit is darkness, his speech is darkness, his action is darkness, his intention is darkness. He gropes about in the murk of his temperament, his desires, and his ignorance; his heart is dark, and his face (5) is dark, for he persists in the original darkness, and nothing of words, deeds, aims, or beliefs suits him except their darkness.
Should even a glimmer of the prophetic light reach him, it would be like the sun shining upon the eyes of a bat (6).
