Nope! And you don't know Sanskrit or Classical Chinese?
So if you have no knowledge of them, how do you know they don't beat the challenge? Honestly, this whole thing seems utterly riddled with holes. I had a lot of respect for Islam a couple years ago, but the more I talk to Muslims, the more I hear Muslims' arguments for Islam and its teachings, the more that declines. Maybe it'd be a good PR policy for Islam to make sure no Muslims ever discuss Islam with kuffar.
Like, my agenda is truth so if the Qur'an was the Word of God I'd genuinely want to know that, if orthodox Islam's claims were true I'd really want to know that. But they've just been so unpersuasive!
