أَلَمْ تَرَ كَيْفَ ضَرَبَ اللَّهُ مَثَلًا كَلِمَةً طَيِّبَةً كَشَجَرَةٍ طَيِّبَةٍ أَصْلُهَا ثَابِتٌ وَفَرْعُهَا فِي السَّمَاءِ (24)
(14:24) Do you not see to what Allah' has likened the `Pure Word' *34 ? It is like a good tree which has got deep roots into the earth and whose branches have spread high up into heaven. *35
*34) Though the expression literally means "Pure Word," here it stands for "Truthful Saying and Righteous Creed". According to the Qur'an, this 'Saying' and 'Creed" are the acceptance of the doctrine of Tauhid, belief in Prophethood and Revelation, and in the lift of the Hereafter, for it declares these things to be the fundamental truths.
*35) This is to show the strength and extent of the "Pure Word". As the entire system of the universe hangs upon the Reality contained in this "Pure Word" which the believer Professes, the earth and its entire system co-operates with him and the heaven with its entire system welcomes him. There is, therefore, no conflict between him and the Law of nature, and everything in its very nature extends its help to him.
