(18:8) In the end, We will turn all that is in it into a bare plain. *5

And indeed, We will make that which is upon it [into] a meaning

*5) V. 6 was addressed to the Holy Prophet, but vv. 7-8 have been directed to the disbelievers indirectly, as if to say, "You must understand it clearly that all the things that you see in the world and which allure you, are a transitory adornment which has been arranged merely to test you, but it is a pity that you have been involved in the misunderstanding that all these things have been created to cater for your pleasure and enjoyment. That is why the only aim and object of life you have set before you is: "Eat, drink and be merry.." As a result of this you do not pay any attention to your true and real well-wisher. You must understand it well that these things have not been provided for pleasure but are actually a means of testing you. You have been placed among them to see which of you is allured by these from the real aim of life and which of you keeps steadfast in the worship of Allah, for which you have been sent to the world. All these things and means of pleasure shall come to an end on the Day your examination is over and nothing will remain on the earth because it will be turned into a bare plain."
