Pakistan requires a Muslim citizen who applies for a passport to subscribe to the following declaration:
1.I am a Muslim and believe in the absolute and unqualified finality of the Prophethood of Muhammad the last of the Prophets.
2.I do not recognize any one who claims to be a prophet in any sense of the word or any description whatsoever, after Prophet Muhammad or recognize such a claimant as a prophet or a religious reformer as Muslim.
3.I consider Mirza Ghulam Ahmad Qadiani to be an impostor prophet and an infidel and also consider his followers whether belonging to the Lahori, Qadiani or Mirzai groups, to be non-Muslims.
The official reason given is that Ahamadis are not considered Muslims by theSaudi who will not allow then to do hajj or even ummah.
This is a good question though: Ahmadis say they are Muslims, but many other Muslims say they are not. So who is right? In fact, there is no overall authority that can say who is and who is not a Muslim. Therefore, I guess,if debunker wants to call himself a Muslim, he must be a Muslim of sorts, but the label means very little. It would be better to say that debunker is,well, debunker! Do we really need to give him a label in order to understand him? If yes,is one label enough?
