How are the spying the prophet?

They could have access to his phone calls, movements, and even his questions here. And that a islamic john *** dealer. He asks his sister. Is she having access by the police or by the mayor? Is that direct of they have someone doing the dirty job? How will the prophet stop that and judge those persons? He has not the superpowers yet: fire from heaven, guns and curses. So: People are having access to the prophet's informations but by an illegal way. Whether someone are giving informations, whether the islamics are having direct access to his informations but it would be very difficult to have access to phone calls etc. Region of the city of the evil.
