What is the ruling on the money the state obtains from taxes on citizens, and is it considered forbidden in itself or due to its acquisition, knowing that the state possesses natural resources and spends these taxes as wages for citizens in exchange for their work, and are these wages forbidden for the citizens?

Your question has two parts:

First: The ruling on taxes. These are of two types: forbidden if taken unjustly, and permissible if they are for fulfilling the needs of the Ummah and the state's resources are insufficient for that.

Second: Employees receiving their salaries from the state, which collects both permissible and impermissible taxes. There is no objection to this matter.
