Every mosque, every Imam, every muezzin in Turkey is under the supervision of the Turkish authorities. According to Turkish law, Imams are considered as civil servants trained by the state. Without a state license, it is illegal to preach a sermon in the mosque. Right now the Diyanet controls aprox. 87000 mosques (85k in Turkey, 2k abroad). Every Friday sermon across Turkey is delivered by Diyanet. So, you and your friends are going to listen to the same sermon even if you don't live in the same state/province/city. And of course, every religious school/madrasa is controlled by Diyanet as well in Turkey.

This system proved to be extremely successful to counter religious radicalism.To tell you the truth, reality is a bit more complex. Diyanet was and still is a heritage of the Kemalist revolution under M.K. Atatürk.
Maybe this system isn't fitting exactly to Pakistani needs but I'm sure that Pakistan needs urgently more centralization and more regulation in religious affairs.
