"Know that the life of this world is only play and amusement, pomp and mutual boasting among you, and rivalry in respect of wealth and children. (It is) like a rain (Ghayth), thereof the growth is pleasing to the tiller; afterwards it dries up and you see it turning yellow; then it becomes straw. But in the Hereafter (there is) a severe torment, and (there is) forgiveness from Allah and (His) pleasure. And the life of this world is only a deceiving enjoyment." [57:20] Allah the Exalted degrades the significance of this life and belittles it by saying "that the life of this world is only play and amusement, pomp and mutual boasting among you, and rivalry in respect of wealth and children."
Meaning, this is the significance of this life to its people, just as He said in another Ayah,
"Beautified for men is the love of things they covet; women, children, much of gold and silver (wealth), branded beautiful horses, cattle and well-tilled land. This is the pleasure of the present world's life; but Allah has the excellent return with Him." (3:14)
Allah the Exalted also sets a parable for this life, declaring that its joys are fading and its delights are perishable, saying that life is,
"Like a rain (Ghayth)," which is the rain that comes down to mankind, after they had felt despair. Allah the Exalted said in another Ayah,
"And He is it Who sends down the Ghayth (rain) after they have despaired." (42:28)
Allah's statement, "thereof the growth is pleasing to the tiller" meaning that farmers admire the vegetation that grows in the aftermath of rain. And just as farmers admire vegetation, the disbelievers admire this life; they are the most eager to acquire the traits of life, and life is most dear to them, "afterwards it dries up and you see it turning yellow; then it becomes straw."
Meaning, that vegetation soon turns yellow in color, after being fresh and green. After that, the green fades away and becomes scattered pieces of dust. This is the parable of this worldly life, it starts young, then matures and then turns old and feeble. This is also the parable of mankind in this life; they are young and strong in the beginning. In this stage of life, they look youthful and handsome. Slowly, they begin growing older, their mannerism changes and their strength weakens. They then grow old and feeble; moving becomes difficult for them, while doing easy things becomes beyond their ability. Allah the Exalted said, "Allah is He Who created you in (a state of) weakness, then gave you strength after weakness, then after strength gave (you) weakness and gray hair. He creates what He wills. And He is the All-Knowing, the All-Powerful." (30:54)
This parable indicates the near demise of this life and the imminent end of it, while in contrast, the Hereafter is surely coming. Those who hear this parable should, therefore, be aware of the significance of the Hereafter and feel eagerness in the goodness that it contains,
"But in the Hereafter (there is) a severe torment, and (there is) forgiveness from Allah and (His) pleasure. And the life of this world is only a deceiving enjoyment."
Meaning, surely, the Hereafter that will certainly come contains two things either severe punishment or forgiveness from Allah and His good pleasure.
Allah the Exalted said, "And the life of this world is only a deceiving enjoyment."
Meaning, this life is only a form of enjoyment that deceives those who incline to it. Surely, those who recline to this life will admire it and feel that it is dear to them, so much so, that they might think that this is the only life, no life or dwelling after it.
Yet, in reality, this life is insignificant as compared to the Hereafter.
