Seest thou not how Allah sets forth a parable? - A goodly word like a goodly tree, whose root is firmly fixed, and its branches (reach) to the heavens,- of its Lord. So Allah sets forth parables for men, in order that they may receive admonition.
And the parable of an evil Word is that of an evil tree: It is torn up by the root from the surface of the earth: it has no stability.
