It is funny indeed that an Islamic newspaper suggests that this Bible could be an old copy of the medieval Gospel of Barnabas written in Aramaic! The medieval Gospel of Barnabas was first devised in Spanish and Italian though. Further, its author never claimed that Jesus got His "true Gospel" written in Aramaic or Hebrew rather than Greek.
Muslim scholars, having been spurred by people like Dan Brown or Bart Ehrman, have recently proposed that the New Testament cannot be genuine because it was written in none of Jesus' languages (Hebrew and Aramaic). This language issue is often brought up by Muslims who object to the authenticity of the canonical Gospels. Ironically, Muhammad's demon was definitely unaware of this argument because he said that Jesus was given a revelation named Injil, which is the Arabic transliteration of the Greek word Euangelion!!!
Christians, fasten your seatbelts and be ready for a new conspiracy theory targetting the Bible and Christian tenets.
