Is there immortality in Paradise, and what are its characteristics, and how will it be, and what will the immortal ones do forever? And will Allah Almighty create another world and another earth after the annihilation of this world?

There should be no doubt about the eternality of the inhabitants of Paradise, even if we are ignorant of its essence and characteristics, because the affairs of the Hereafter are not to be measured by the affairs of this world. There is nothing in this world that is in Paradise except for the names. And the imagination that eternity in Paradise causes boredom and weariness is a corrupt analogy, for there is no boredom in Paradise. As for what the people of Paradise specifically do, no text has been reported concerning it, so we entrust its knowledge to Allah Almighty.
