i dont disagree with that statment, because there are fals prophets, as you will see, the bible says they wil not mention christ or beleive in him, whereas out prophet (s.a.w) did...also the bible mentions about how, for a prophet to be false, his prophecies will be unreliable, and hence not happen, i dont know much about Muhammad (s.a.w) because i have not long been muslim for long, but as far as i know he has not prophecised any false prophecies!
so therefore if we look at these bible statements to disprove the prophethood of Muhammad (s.a.w) we cannot do it, as he is a prophet of Allah
