Dr.Sahib, I had the same question in my mind, that which pledge or covenant , all Ahmedis are relying on? Did Muhammad SAW ever tell his people about any prophet except the Jesus Son Of Mary, according to the Hadith which must be a fabricated Hadith because according to the Quran he is a dead prophet. Why would Allah Almighty take a pledge from Muhammad SAW to tell his people to support a prophet after sending a the Final Shariah?
There's another reference they usually represent. I would like to request your comments regarding it also.
وما اهلكنا من قرية الا لها منذرون
26:208We never annihilated a community unless it had been warned.
According to their claim all calamities of the world are because of the rejection of the "warner" of the end times.
My question is why didn't Allah Almighty destroy the people who rejected His "Best Prophet SAW"?
