A few months ago, the Ahmadi trolls chased Dr. Shadee Elmasry, they called him a terrorist and asked the U.S. govt. to investigate him. This is the common Ahmadiyya tactic vs. their critics. They did the same to Professor Johnathan Brown and basically all Sunni/Shia leaders here in America. About a year ago, Dr. Elmasry recorded a lecture on Prophethood, we came across this by chance, we have cut out the specific part of this lecture wherein he explains the Ahmadiyya. The full video is also posted. It is important to note that he mentions the death of MGA on the toilet, you can read that full story here, and fully and properly referenced.
The full video—see the 17:27 onwards..
