Imam Bukhari and Ibn Jarir have cited this view of Hadrat Ubayy bin Ka'ab: "We took the Holy Prophet saying: “If the son of Adam had two valleys full of wealth, he would long for a third valley; the son of Adam's belly cannot be filled but by earth, to be from the Quran until Alhakum at takathur was sent down.”
The mutual rivalry for piling up (the good things of this world) diverts you (from the more serious things), (Quran 102:1)
Acquisitiveness, that is, the passion for seeking an increase in wealth, position, the number of adherents or followers or supporters, mass production and mass organization, may affect an individual as such, or it may affect whole societies or nations. Other people's example or rivalry in such things may aggravate the situation. Up to a certain point it may be good and necessary. But when it becomes inordinate and monopolizes attention, it leaves no time for higher things in life, and a clear warning is here sounded from a moral point of view. Man may be engrossed in these things till death approaches, and he looks back on a wasted life, as far as the higher things are concerned.
Until ye visit the graves. (Quran 102:2)
But nay, ye soon shall know (the reality). (Quran 102:3)
Again, ye soon shall know! (Quran 102:4)
Nay, were ye to know with certainty of mind, (ye would beware!) (Quran 102:5)
Ye shall certainly see Hell-Fire! (Quran 102:6)
Again, ye shall see it with certainty of sight! (Quran 102:7)
Then, shall ye be questioned that Day about the joy (ye indulged in!). (Quran 102:8)
We shall be questioned, i.e., we shall be held responsible for every kind of joy we indulge in-whether it was false pride or delight in things of no value, or things evil, or the enjoyment of things legitimate, -the last, to see whether we kept this within reasonable bounds.
Here is another teaching as well. Anybody who is serious in his faith knows that after earthly life there is an eternal life for his soul. This is a timeless dimension where one doesn't have to push desires and satisfaction of instincts to tight limits. Reaching the graveyard doesn’t mean that one reached to the end. Only those think like that who are not conscious about afterlife and want to accumulate greedily everything in the limited period of the physical life. This unquenchable thirst removes him from happiness and welfare.
