Surah 35. Fatir, Ayah 19

Now we are offered some contrasts between those who obey Allah's Law and are thus citizens of Allah's Kingdom and those who are rebels against Allah's Kingdom and are thus outlaws. How can they be considered alike? The godly are like those who see, as contrasted with those who are blind; and their motives and actions are like the purest and highest Light, contrasted with the depths of darkness; or, to take another metaphor, their lives are like the genial and warmth-giving heat of the sun, which benefits all who come within its influence, contrasted with the chilly shadows of gloom in which no vegetation flourishes.
