GOOD WORDS & EVIL WORDS
Have you not considered how God sets forth a parable of a good word (being) like a good tree, whose root is firm and whose branches are in heaven,
Yielding its fruit in every season by the permission of its Lord? And God sets forth parables for men that they may be mindful.
And the parable of an evil word is as an evil tree pulled up from the earth's surface; it has no stability.
Surah Ibrahim; 14:24-26
[Chapter of Abraham, Verses 24-26]
