There is, in their stories, instruction for men endued with understanding. It is not a tale invented, but a confirmation of what went before it,- a detailed exposition of all things, and a Guide and a Mercy to any such as believe.Yusuf 111
Is it not a guidance to such men (to call to mind) how many generations before them We destroyed, in whose haunts they (now) move? Verily, in this are Signs for men endued with understanding.Ta'ha 128
And if indeed thou ask them who it is that sends down rain from the sky, and gives life therewith to the earth after its death, they will certainly reply, "Allah!" Say, "Praise be to Allah!" But most of them understand not.Al-Ànkabü 63
Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colors: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. Truly, in this, is a Message of remembrance to men of understanding.
