And the example of an evil word-and it is the word of disbelief-is like an evil tree in its consumption and its food, and it is the colocynth tree, uprooted from above the earth; because its roots are near to the surface of the earth having no firm root, nor any ascending branch, and likewise the disbeliever has no firmness for him nor any good in him, and no righteous deed of his is raised to Allah.
