How can I sell a car if it is still on loan before leaving the UAE?

A car is under a car loan from a bank like monthly payment and the person who has taken the car loan goes back to their own country.

Can someone else either pay the remaining money for that car and claim the title of ownership or pay its registration or Mulkiya (ownership) and keep on driving it?

Is it possible or how long will it take for the car to get taken by the bank?
