Actual history, as in based on historical sources we have. Of course I do believe the accounts of the church to be from the apostles. But heres the defeater of islam.
Behold! Allah said: "O Jesus! I will take thee and raise thee to Myself and clear thee (of the falsehoods) of those who blaspheme; I will make those who follow thee SUPERIOR to those who reject faith, TO THE DAY OF RESURRECTION: Then shall ye all return unto Me, and I will judge between you of the matters wherein ye dispute." S. 3:55
This is a claim that can be verified in history. We should be able to see a group of early christians (if this is true) that preached certain aspects about Jesus while excluding themselves from the orthodox, gnostic or Judaising parties in early Christianity. They should, Deny Jesus as God, They should deny Jesus being killled on the cross, they should affirm Jesus being assumed into heaven, they should affirm Jesus having a physical body, they should affirm Jesus gave a book called the gospel, they should affirm Jesus spoke about a promised one called Muhammad. These are the things teh quran claims Jesus taught, but we find no trace of any group anywhere that existed and believed such things. None whatsoever, but the claim is magnafied once we see the quran says they will be victorious to the day of ressurection. They are not even mentioned in history, instead the party that became victorious were the Orthodox churches, those who taught Jesus was God, died and was ressurected.
I have not heard a decent islamic responce to this, it is a pure matter of believing the quran against what we should expect. IE some reference to this strange group if they were victorious and superior to all others. That was teh church, not this non existing band of apostles and subsequent followers.
