Now that's a good question, let's clear this up, you said that prophecies of a prophet must be true, i agree with you , you also said that Muhamed PBUH testified that the Messiah is a prophet, with is proven in history by sources no one can deny. But what is NOT PROVEN is the crusification of Jesus PBUH, the churuch, the pope, and all the preists of the world CAN NOT prove that , all you have to do is to look in the history of chuches and the differences between different sides about the crucification of Jesus, there are some who denied it totally , some who accepted it ,and some who stood without making a piont in that issue. that's first, SECOND: you said that Jesus predicted that he would be crucified, I challenge you to bring one evidence from the bible that proves that, it's a matter of heaven or hell so let's not talk without evidence please, he stated that he would be betrayed and that's what muslims believe, he got betrayed : And as they did eat, he said, Verily I say unto you, that one of you shall betray me. MATT 26/21 bring me the evidence and let's talk with ration for god's sake. jesus never said that he would get crucified nor resurructed, it's only guessings and claims, if you wanna talk with mind and proven facts you're welcome, if not just keep on learning from your people what they can't explain
