The importance of roots in plants

أَلَمْ تَرَ كَيْفَ ضَرَبَ ٱللَّهُ مَثَلًۭا كَلِمَةًۭ طَيِّبَةًۭ كَشَجَرَةٍۢ طَيِّبَةٍ أَصْلُهَا ثَابِتٌۭ وَفَرْعُهَا فِى ٱلسَّمَآءِ

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.

وَمَثَلُ كَلِمَةٍ خَبِيثَةٍۢ كَشَجَرَةٍ خَبِيثَةٍ ٱجْتُثَّتْ مِن فَوْقِ ٱلْأَرْضِ مَا لَهَا مِن قَرَارٍۢ

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.
