Listen to us good … Many people will NOT reject Mahdi … That is your fantasy … Read the ahadith about how the Mahdi will unify us … He cannot unify and at the same time many people will reject him … Look in MGA’s case … He did not unify us and many people rejected him … Now show us in the prophecies of Al-Mahdi that he will be rejected by a Muslim majority … Instead you raise the argument of age old civilisations who rejected their own prophet, but you fail to show any applicability of that to Al-Mahdi … Come on consider it a challenge.
