After man and jinn have entered Jannat and Jahannum, will Allah Ta'ala create more worlds and beings?

Answer

In fact, Allah Ta'ala has millions, billions, trillions of universes which are inhabited by innumerable species of creation of a vast number of kinds of intelligences. And, even after the destruction of this world and after man's and jinn's fate has been decided, Allah Ta'ala will create as He wishes. This world and man are merely tiny particles in Allah's vast and limitless creation.
