It is not permissible to dispose of pledged property

Question: If one of my properties is pledged to the state, is it permissible for me to dispose of it by selling it?

Answer: If it is pledged to the state or to anyone else, you have no right to dispose of it except with the permission of the pledgee; because his right has become attached to it; so you have no right to dispose of it except with his permission, whether the pledgee is the state or someone other than the state.
