So, again, do you think that any person claiming to be God's messenger is delusional or not? Why is that question so hard?
If you meant just Mohammed, then why didn't you say "Mohammed" instead of "anyone"?
I understand what your second sentence meant, but it has no bearing on the truth or lack thereof of the first sentence. Your two sentences are related to a degree, and they make perfect sense, but that doesn't mean they are true, and the second one cannot be used to verify the truth of the first one. It's more than being skeptical. In your first sentence, you go beyond skepticism, which is why I asked in the first place. You go to the point of certainty that you're right. I just wondered how you know that for sure.
My reading skill is fine, and there is no nit-picking involved. It's a simple question that you have so far avoided answering, and I simply can't figure out why.
