How is actually our life in this world?

 

Verse 24 of Chapter 10:

This worldly life may be likened to the produce of the earth: We sent rain-water from the sky, and the crops of which man and animals eat, grew up luxuriantly. Then at that very time, when the land was at its best, and the crops had ripened and decked out and the owners were presuming that they would be able to benefit from them, Our Command came all of a sudden by night or by day, and We destroyed it so thoroughly as though nothing had existed there the previous day. Thus We expound Our Signs in detail for the consideration of those people who are thoughtful.


Verse 36 of Chapter 47:
The life of the world is but a sport and a pastime. And if ye believe and ward off (evil), He will give you your wages, and will not ask of you your wordly wealth.

Verse 20-21 of Chapter 57:

Know it well that the life of this world is nothing but a sport and pastime, and a show and boasting among yourselves and a rivalry in wealth and children. Its example is of vegetation after a shower of rain, which delighted the tillers, then the same ripens and you see it turn yellow, then it becomes straw. Contrary to this, in the life to come there is severe torment and forgiveness from Allah and His good pleasure. The life of this world is nothing but illusion. Therefore, strive in rivalry with one another in hastening towards the Paradise the vastness of which is like the vastness of the heavens and earth, prepared for those who have believed in Allah and His Messengers. This is Allah's bounty which He bestows on whomever He wills, and Allah's bounty is immense!
