what happens next ?

So after the day of jugement and each person goes to bis rightfull
Abode may it be heaven or hell
Ans after the people of Hannah have their greatest desires doubles to limitless potential
What happens after all of this ? What is the reason for existing after
Acheiving at all (immortality and all sorts of rewards)
Will allah créateur another entity after us? Or tha is it ?

No, nobody can say if Allah swt will create another entity. What we know is that our lives are forever.
