What is the difference between the levels of Paradise, and is everything a Muslim wishes for in Paradise?

The inhabitants of Paradise will vary in their ranks and stations according to their deeds, as stated in the texts of the Qur’an and Sunnah. This difference, however, does not negate their attainment of all that they wish for and desire, because they will not wish for what is beyond their rank. Rather, they will be content with what Allah has given them and will realize that it is from His bounty, and their souls will not yearn for what is higher. Thus, they will differ [in rank] while each of them remains content with their state and does not wish for more than what they have.
