The Koranic reasons stating Creation is not created in a futile way
There is no falsehood throughout the universe as it is mentioned in the Koran the world (Creation) has been absolutely created with purpose:
1- Or do those who commit evil deed reckon that we will treat them exactly like those who believe and perform honorable actions, just as if their mode of living and their way of dying were equivalent? How lamely do they judge! True purpose and so every soul may be rewarded for whatever it has earned, and they not be harmed.(45: 21-22)
2- Those who stray from Gods path will have severe torment because they have forgotten the Day of Reckoning! We did not create Heaven and Earth and whatever [lies] in between them to no purpose. That is the opinion of those who disbelieve. Those who disbelieve should beware of the fire!
Shall we treat those who believe and perform honorable deeds just like mischief –makers on earth? Or should we treat those who do their duty, like lawbreakers? (38:26-28)
3- We did not create Heaven and Earth and whatever lies in between them while just – playing around.
If we had wanted to adopt it as a pastime, we would have adopted it within our very presence, had we ever done so. Rather we hurl Truth against falsehood, so it knocks it down. Then it disappears, you are the ones [who need] to worry because of what you are describing. (21: 16-18)
All these verses refer to the point that Creation requires Resurrection.
