If one of the people of Paradise desires a house or a palm tree, and has not performed the specific deed for that reward, will he attain what he desires?

Allah gives His servant in Paradise whatever he desires and wishes for, as the Almighty said: "And therein is whatever the souls desire and [what] delights the eyes," and His saying: "For them therein is whatever they wish, [abiding] eternally." This does not negate the differentiation in ranks among the people of Paradise according to their deeds, as the Almighty said: "And that is Paradise, which you have been made to inherit for what you used to do." Despite this disparity, each of them is content with what Allah has given him, and finds no envy in his heart, as the Almighty said: "And We will remove whatever is in their breasts of resentment, [as] brothers, facing each other on couches."
