It is obvious that the issue of Khelafat was always a difficult issue in the history of Islam and one that affects Islam a lot:
Several ahadith approve Ali's (rta) khilafat. Abu Bakar's (rta) khilafat was either an accident or deliberation. And in the light of the above; was he a true khalifah al-Rasool? Was Muawiya's decision to appoint Yazid as his successor, legitimate especially in the presence of Hussayn?
My question is why there are only four khalifas and not a fifth one? Furthermore I would like to ask how I can best explain to an Ahmadi about the true religion.
