The example of [this] worldly life is but like rain which We have sent down from the sky that the plants of the earth absorb - [those] from which men and livestock eat - until, when the earth has taken on its adornment and is beautified and its people suppose that they have capability over it, there comes to it Our command by night or by day, and We make it as a harvest,1 as if it had not flourished yesterday. Thus do We explain in detail the signs for a people who give thought.
Translation: Saheeh International (English)
1 Its vegetation having been cut down or uprooted, i.e., utterly destroyed.
The example of the life of this world, and the enjoyment in it, and how quickly it comes to an end, is that of the rain which is absorbed by the plants of the earth, from which people eat grains and fruits, and animals benefit from its vegetation. When the earth has taken on its bright colour and looks beautiful because of the different plants growing on it, and the people think that they will be able to harvest and gather what has grown, Allah’s command comes to destroy it, so as if it had been harvested and not been full of anything. This is how Allah makes clear the true reality of the wroldly life and how He expounds upon His verses and signs so you may think about them and take a powerful lesson.
