None of them ever said that there was any other prophet after Hazrat Muhammad (PBUH) only Ahmedis
And remember Allah will ask you at Qiyamah.. there were few of my people who tried to tell you the truth and you were still asking me to come and speak. Why you still never wanted to believe them? what kept you away to believe what they said. Now I am (Allah) in front of you and thats was the curtain between you and ME to believe and have faith.
