[6:32] The life of this world is no more than illusion and vanity, while the abode of the Hereafter is far better for the righteous. Do you not understand?!

[30:39] "O my people, this first life is a temporary illusion, while the Hereafter is the eternal abode."

[57:20] Know that this worldly life is no more than play and games, and boasting among you, and hoarding of money and children. It is like abundant rain that produces plants and pleases the disbelievers. But then the plants turn into useless hay, and are blown away by the wind. In the Hereafter there is either severe retribution, or forgiveness from GOD and approval. This worldly life is no more than a temporary illusion.
