Sura Ibrāhīm 14:24

أَلَمْ تَرَ كَيْفَ ضَرَبَ ٱللَّـهُ مَثَلًا كَلِمَةً طَيِّبَةً كَشَجَرَةٍ طَيِّبَةٍ أَصْلُهَا ثَابِتٌ وَفَرْعُهَا فِى ٱلسَّمَآءِ

a-lam tara kayfa ḍaraba allāhu mathalan kalimatan ṭayyibatan kashajaratin ṭayyibatin aṣluhā thābitun wa-farʿuhā fī l-samāʾi

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.
