The Khalifas comments on Mujadids
As we know, Ahmadis don’t believe in Muajdids anymore, as long as they have Khilafat, they don’t need any prophets or any mujadids, and this runs contrary to the famous hadith on Mujadids.  Further, the Messiah wasn’t even supposed to have any Khalifa’s, he is supposed to physically return to Earth and convert the entire world to Islam, hence ending Jihad and Jizya.  So Ahmadis are waaaaaay out in left field with this logic.
