On what grounds? And how do you know your c=source is accurate?
My sources are varied and partly corroborative. And the historical facts cannot be denied.
You are simply assuming that whatever some bloke said must be true - even though some of it is demonstrably untrue.
The history of the expansion of the Muslim empire was recorded by various sources, some eye-witnesses. There is also archaeological evidence. You don't seem to uxnderdstrand how the study of history works.
Also, Bahaullah was not there so you can't use what he said as an argument, especially as he doesn't cite any supporting evidence.
What are you taking about? There is plenty of evidence to show the Islamic empire expanding massively over the years during and after Muhammad's reign.
Unfortunately for your argument, you cannot even show that a god exists, so you can't claim that Bahaullah was anything to do with that god. The usual circular logic claims made by Bahais are obvious nonsense.
Which is why your position is untenable.
"Burden of proof" dear thing. You are claiming that a god exists, and that Bahaullah was his messenger. Therefore it is
your responsibility to show said god exists before you can make any further claims involving it. And you can't do that. You simply resort to circular logic.
lol. Don't need to. I just need to show that my explanation is more likely, or my argument better supported than your god claim. And it clearly is.
But as you cannot provide anything to support your claim, it can be dismissed.
You believe it to be true, but you are unable to show that your belief is true.
I could post a number of passages on how other groups or individuals have a very different view of Islam. Not sure what your point is?
