The Jews used to allege that a Roman soldier named Pandora had raped mother Mary (God Forbid) and thus Jesus had been born. That is why they called Jesus "Bin Pandora, the son of Pandora". But Prophet Muhammad (peace be upon him) put an end to this abuse against mother Mary and Jesus. Today about one and half billion Muslims believe in the miraculous birth of Jesus, that he was born without any male intervention. Suppose, if somebody's father has not been home to meet him and his mother for the last 5 years and suddenly one day his mother comes and tells him that somehow she dreamed about his father and she became pregnant. Would he believe his own mother? No, of course not! But today we, Muslims believe that Jesus was born miraculously without any male intervention. A son would not believe his own mother, but one and half billion Muslims believe that Mary was a virgin, when she gave birth to Jesus. We believe this on the solitary statement of Prophet Muhammad (peace be upon him). It is impossible for any Christian to logically prove the miraculous birth of Jesus and even many modern-day Christians even do not believe in the miraculous birth of Jesus. But we, one and a half billion Muslims believe in the miraculous birth of Jesus on the solitary statement of Prophet Muhammad (peace be upon him). The Christian World can never repay what obligation Muhammad (peace be upon him) had done upon Jesus and his Mother Mary by supporting the miraculous birth of Jesus and his miracles.
Furthermore, Prophet Muhammad (pbuh) is the final prophet and the spirit of truth, whose coming Jesus promised. As Jesus said in the Gospel of John chapter 16 verse 12-14: "I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth is come, he will guide you unto all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. He shall glorify me". Someone asked us that did Muhammad (peace be upon him) glorify Jesus? Yes, as it is clear from what we mentioned about Muslim belief in the miraculous birth of Jesus that Muhammad (peace be upon him) truly glorified Jesus by putting an end to the years of abusing.
Islam is the only non-Christian faith, which makes it an article of faith to believe in Jesus. A Muslim can not be a Muslim, unless he believes in Jesus Christ. We believe that he was a mighty Messenger of God. We believe that he was the Messiah, translated Christ, that he was born miraculously without any male intervention. We believe that he gave life to the dead with God's permission and healed those born blind and lepers. Can any Christian in the World today logically prove that Jesus gave life to the dead? No! In fact, any sensible Christian would shy away from mentioning this in front of any atheist because the mockery that he would make of this belief can not be exaggerated. But one and half billion Muslims believe this, not that the Christians proved it to us, but only because Prophet Muhammad (peace be upon him) said so.
Chapter 19 of the Glorious Qur'an is named after Mary, the mother of Jesus. Please note that there is no such book or chapter in the Bible, which is named after Jesus or his mother Mary.
So the Christians should respect Prophet Muhammad (peace be upon him) and oppose all such bigotry, first because of the respect, love and reverence that Jesus and Mother Mary get from Muslims only because of Prophet Muhammad (peace be upon him). Second, because Prophet Muhammad (peace be upon him) is the final prophet and the spirit of truth prophesied by Jesus himself. Third, because Jesus said that you should even love your enemy and after all Muhammad (peace be upon him) is not even the enemy, but in fact the man whom Christianity is the most indebted to.
Even after all this if any Christian believes that abusing Prophet Muhammad (peace be upon him) should be allowed, he surely can not be a follower of Jesus Christ. But there are those, who are upset with the movie, but say that it should be allowed because there is freedom of speech. By saying this, they probably are believers in freedom of speech, but they surely are not believers in Jesus Christ.
