What are the fundamental beliefs of Ahmadis?

Re: What are the fundamental beliefs of Ahmadis?

Anyone who calls himself/herself a Muslim and professes faith in the Kalima "There is no God but Allah and Muhammad (SAW) is the messenger of Allah" is a Muslim. No-one else has a right to declare him non-Muslim.

A Muslim's goal should be to preach and invite people into Islam, not kick the fellow-Muslims out of it.
