"What is wrong with you (Christian) folk?" Jesus is telling you in the most unambiguous language that he is not a spirit - not spiritualised, not a resurrected person, and yet the whole Christian world believes that he was resurrected, i.e. spiritualised. Who is lying, you or him?
How is it possible that you, each and every Christian, are reading your Bible in your own mother tongue and yet each and every groups is made to understand the exact opposite of what they are reading? If you read the Bible, say, in Hebrew, and pleaded that you did not understand what you were reading, I can appreciate this fact. If you read it in Greek and pleaded that you did not really understand the implications of what was written; I can appreciate this fact also. But the anomaly is that you are reading the Book, each and every one, in his own mother tongue, and are trained to understand the opposite of what is written. How have you been brainwashed, or rather, how have you been "Programmed," as the Americans would put it?
"Please tell me as to who is lying? Is it Jesus or a thousand million Christians of the world? Jesus says: "No!" to his being resurrected, and all of you say: "Yes!" Whom are we Muslims to believe, Jesus or his so called disciples? We Muslims would rather believe the Master. Did he not say: "The disciple is not greater than the Master."? (Matthew 10:24)
Read with your mind and understanding faculty's window open :
"...Jesus himself stood in their midst, and said unto them, Peace be unto you...But they were terrified, and supposing that they were seeing a spirit... And he said unto them,.. 'Behold my hands and my feet, that it is I myself: handle me and see; for a spirit has no flesh and bones, as you see me have'... And showed them his hands and feet... And while they yet believed not for joy and wondered, he said unto them, 'Have ye here any meat?'.. And they gave him a piece of broiled fish, and of a honeycomb... And he took it, and did eat before them." (Luke 24:36-43)
