Know that: World's life is only Sport and Play

[57. Surah Al-Hadid : Ayah 20]
Know that this world's life is only sport and play and gaiety and boasting among yourselves, and a vying in the multiplication of wealth and children, like the rain, whose causing the vegetation to grow, pleases the husbandmen, then it withers away so that you will see it become yellow, then it becomes dried up and broken down; and in the hereafter is a severe chastisement and (also) forgiveness from Allah and (His) pleasure; and this world's life is naught but means of deception.

[6. Surah Al-An'am : Ayah 32]
And this world's life is naught but a play and an idle sport and certainly the abode of the hereafter is better for those who guard (against evil); do you not then understand?

[29. Surah Al-'Ankabut : Ayah 64]
And this life of the world is nothing but a sport and a play; and as for the next abode, that most surely is the life-- did they but know.

[47. Surah Muhammad : Ayah 36]
The life of this world is only idle sport and play, and if you believe and guard (against evil) He will give you your rewards, and will not ask of you your possessions.

[35. Surah Fatir : Ayah 5]
O men! surely the promise of Allah is true, therefore let not the life of this world deceive you, and let not the arch-deceiver deceive you respecting Allah.

[87. Surah Al-A'la : Ayah 16-17]
Nay! you prefer the life of this world, While the hereafter is better and more lasting.
