The idea that this world is a temporary, illusory existence is supported in the Quran where it emphasises the transient and deceptive nature of worldly life, describing it as a test for humanity.

This concept aligns with optical illusions, which deceive the eyes and mind, providing a metaphor for how the world can mislead us from ultimate truths.

This world is temporary
“And this worldly life is nothing but diversion and amusement. And indeed, the Hereafter—that is the real life, if only they knew.” (Quran 29:64)

This verse highlights that the worldly life is not the ultimate reality but a fleeting diversion.

The deceptive nature of the world
“Every soul will taste death, and you will only be given your [full] compensation on the Day of Resurrection. So he who is drawn away from the Fire and admitted to Paradise has attained [his desire]. And what is the life of this world except the enjoyment of delusion?”-  (Quran 3:185)

The phrase “enjoyment of delusion” compares worldly pleasures to illusions, fleeting and insignificant in the face of eternity.

Material wealth as a test
“And present to them the example of the life of this world: [it is] like rain which We send down from the sky, and the vegetation of the earth mingles with it. Then it becomes dry remnants, scattered by the winds. And Allah is over all things competent.” (Quran 18:45-46)

This verse draws an analogy between the world and something transient, fading away like a mirage.

Now we are talking about optical illusions, it demonstrate how our senses can be deceived. Just as our eyes can misinterpret visual stimuli, our hearts and minds can misinterpret the significance of this world.

For example:

A mirage in the desert appears like water in the desert but vanishes upon approach. Similarly, worldly gains may seem fulfilling but ultimately leave one unsatisfied.

“But those who disbelieve—their deeds are like a mirage in a lowland which a thirsty one thinks is water until, when he comes to it, he finds it is nothing.” (Quran 24:39)

Another common example often taught in behaviour psychology classes is about The Checker Shadow Illusion. This illusion tricks the brain into seeing two squares of different shades as the same color due to contextual cues.

Similarly, worldly life may appear meaningful but lacks true substance compared to the hereafter.

In a nut shell this world can be seen as an illusion, much like optical illusions that deceive our senses.

The Quran reminds us to focus on the eternal reality of the hereafter, understanding that the pleasures and pains of this life are tests and temporary distractions.
