True freedom is doing what Allah wants which is the defintion of freedom in Islam. The 'Abdullah is the only real hur because he is a servant and a slave to Allah and not to creation. The one who is a slave to himself is not free and will never be free until he is freed of himself. And this is why in arabic language the word for freed slave is also the word for master: "Maula"; like we call Allah "Maulana". So the freed slave is the one who is the master of himself.
