Card-carrying non-infidels

ISIS is issuing certificates, good for three months, showing that persons unlucky enough to be caught in their territory are provisionally considered non-infidels:

To whom it may concern,

We hereby notify you that the one named Na’il Salu bin Basaam of the people of the al-Raqa emirate took and satisfactorily passed a course on Repentance.

Based on this, we hereby grant him this certificate confirming that he is not an infidel [kafir] and that it is impermissible to lash, crucify, or rape him, unless a legitimate reason arises for the soldiers of the caliphate or if it’s been established that he has returned to apostasy and wants his freedom.

That's almost as bad as requiring a voter i.d., which is just like a poll tax.
