A tenet of Islam is that both Mohammed and Jesus of Nazareth were both Muslims. Islam says both were prophets sent by Allah. If this were true, then it is mandatory that these two great prophets must coincide exactly in all points and never contradict each other. Did not the same Allah send both of them? Then, aren't even the smallest of contradictions between the two, very big red flags? And there are a great many, which you will see below. Christianity and Islam are necessarily forever diametrically opposed to one another, just as evil and good are. Oral confession of the deity of Jesus Christ is prerequisite to becoming a Christian (Romans 10:9-10). To a Muslim, this is blasphemy. To a Christian it is blasphemy to not attribute divinity to Jesus the Christ. The New Testament could not be clearer on this subject. The heart, core and soul of Christianity is allegiance to Jesus Christ as God, Lord, and Savior! Were Jesus Christ who the Muslim Qur'an who it makes him out to be, then Christianity would be blasphemous and baseless.
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. (Romans 10:9-10)
Surah 5:68 - Say: "O People of the Book! ye have no ground to stand upon unless ye stand fast by the Law (Torah), the Gospel (Injeel), and all the revelation that has come to you from your Lord."Islam says that Jesus did not die. So, again --Islam has proven to be false; because Muhammad claimed the Gospel is true, and all 4 Gospels (Injil) testify that Jesus died and rose from the dead. God does have a begotten Son (not made, but one with the Father), which Islam denies. The Jewish Torah / Taurat (Tawrat) clearly indicated this over 1000 years before Muhammad and Islam. In addition their are collateral 1st century sources that testify that Jesus was put to death. In the "Annals" written by Roman historian Tacitus, in Book XV, Chapter 44 we read "Christus, the founder of the name, was put to death by Pontius Pilate, procurator of Judea in the reign of Tiberius." Roman historian Josephus also wrote about the death and Resurrection of Jesus. Even Satan says that Jesus died on the cross. Also, the Roman Historian Seutonius wrote in his work "Life of the Emperor Claudius" the following about Christians: "and deny the gods of Greece, and worship the crucified sage, and live after his laws." The Roman historian Pliny wrote about Jesus' death in Book X of his Epistles. Julius Africanus, quoting Thallus another Roman historian, who wrote in about 52 A.D. about the miraculas happenings the day the Son of God was killed. He wrote: "On the whole world there pressed a most fearful darkness; and the rocks were rent by an earthquake, and many places in Judea and other districts were thrown down". Like Muhammad, Satan also cringes in fear at the sight of the cross. Read this true Exorcism here.
Surah 29:46 Muslims are told by Allah, not to question the authority of the scriptures of the Christians, saying, "And dispute ye not with the People of the Book, but say, "We believe in the revelation which has come down to us and in that which came down to you; Our Allah and your Allah is one;
Proverbs 30:4 (700 B.C.): "Who hath ascended up into heaven or descended? Who hath gathered the wind in His fists? Who hath bound the waters in a garment? Who hath established all the ends of the Earth? What is His name, and what is His son's name, if thou canst tell?"Even after Allah confirmed the Torah and Gospel, Islamic Mullahs and Imams have tried to sell the lie that the Christian Gospels and Jewish Torah have been corrupted.
(Psalm 2:11-12) Serve the LORD with fear, and rejoice with trembling. Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him.
This a complete lie! This lie is perpetuated by Islam, because of all the historic, scientific, and simple mathematical errors in the Koran/Qur'an - as you'll see below... The Qur'an just doesn't add up.
"They" could not have changed the Christian Gospels after Muhammad, since there are 5,735 (Welte, 2003) manuscripts of the whole or part of the Greek text of the New Testament (Injil) pre-dating Muhammad still in existence. Worldwide, there are 24,800 copies of these original manuscripts. These include the Codex Vaticanus (325-350 AD) located in the Vatican library and the Codex Siniaticus (350 AD) located in the British Museum. There are also 80,000 quotations in the works of early Christian writers which are so extensive that the New Testament could virtually be reconstructed from them without the actual New Testament documents. Then there is the obvious fact that the Christian Gospels were so widely distributed both before and after Muhammad, that any attempt to change (add/subtract) something in the Christian Gospels would have resulted in immediate discovery and condemnation. Additionally, the New Testament was handed down from apostolic times and its genuineness was guarded by Christian churches, and it was zealously watched by enemies of Christianity. A very wide protest would have resulted from both sides were it tampered with. Likewise, the Septuagint edition of the Old Testament was always in the hands of both Christians and Jews, both rivals in religion. Any attempts to change this by either side would have been vigorously attacked.
There are four more "safeguards" for the integrity of the Bible. (1) Jesus Himself read from Isaiah scroll in a Synagogue in Nazareth and declared it as Scripture (inspired from God), Luke 4:16-21; (2) The Dead Sea scrolls, found in 1947, verified the Jewish Torah back to 100 AD to 200 BC, when they were copied. Prior to this discovery, the oldest Torah dated to the 9th century AD. The Dead Sea scroll of Isaiah verified almost exactly the Isaiah scroll copied in the 9th century; (3) Early Church Fathers like Ignatius, Clement of Rome, Clement of Alexandria, Tertullian, Irenaeus, who wrote from between 90-160 AD all cited in their writings Christian Gospel accounts (Guthrie, 1990, page 24); (4) We know that the writings of Moses were preserved as far back as 621 BC. 2 Kings 22 speaks of this at the time of the Israeli King Josiah. Ezra 7:14, Nehemiah 8:1-18, and Jeremiah 36 also speaks of the Jews maintaining Scripture.
Some versions of the Bible from 1881 differ in a few words here and there. However, the essential theological points remain the same and are complete. Bibles we recommend, that have not changed are: Protestants original Authorized King James (1611), Catholics Catholic Douay Reims - older versions
The Christian Bible predates Muhammad and Islam by more than 575 years. The Jewish Torah predates Muhammad and Islam by 1,000 - 3,000 years. Muhammad said for Muslims to read the Bible for "Guidance and Light." For Islam to say they are corrupted, then is to call Muhammad a liar for recommending it.
The same Bible Muhammad would have seen (if he ever did) is in both (1) The Vatican (Codex Vaticanus) and (2) British Museum (Codex Sinaticus). It is all there, including Jesus dying on the cross as atonement for our sins. And, His resurrection, and ascension into heaven - in front of many witnesses. The New Testament is preserved in almost perfect condition in these two Greek texts which both predate Muhammad and Islam by over 200 years.
Everything in the Christian/Jewish Bible is being authenticated by archeology. Consider the Babylonian cylinder inscription of Nabonidus (thought to be the last king of Babylon) which commemorates the reconstruction of a ziggurat at Ur by Nabonidus and records a prayer to Belshazzar (Daniel 5) his son 'the firstborn son, the offspring of my heart'. Not only does this prove that Belshazzar was indeed a member of the Babylonian royal family, which had long been disputed, but it also explains why Daniel is told he could be the third ruler (with Nabonidus and Belshazzar more or less acting as co-regents). Also, consider the 'chariot wheels' divers found in the Red Sea, proving the Hebrew Exodus from Egypy was real; and that the Egyptian army chasing the Jews was drowned by God (Yahweh), just as was recorded in the Jewish Bible.
Muslims should note that nowhere in the Qur'an there is even a suggestion that the Christian Biblical text has been altered or corrupted. The word "tahrif" is never used with reference to the Christian Gospels (Injil). The Qur'an occasionally accuses the Jews of altering their Scripture (like in Surah 5:13); but it never levels this accusation at Christians. It in no way implies that the text of the Gospel of Jesus (Injil) has been corrupted. In fact, the Qur'an attests to the validity of the Christian Gospels, Zabur (Psalms) and the Torah.
The uninspired Qur'an
The Jewish and Christian Bibles were written by "inspired men of God" who immediately committed God's Word to writing. Islam doesn't even have either an original or inspired Qur'an. The Muslim Qur'an was made up supposedly from "memory" from those who supposedly committed the words of Muhammad to memory, and from a few scraps found under a bed. This was originally begun about 15-20 years after Muhammad died at his wife Ayish's home in Medina, and he was lowered into a hole in the ground, where he remains. The compilation was not finished until at least 150 years after Muhammad's death. This "hearsay" argument seriously brings the credibility of the Qur'an into question. But, that's only the beginning. All the errors, including simple mathematical and historical errors you will see in the Qur'an below renders it impossible to be a divine revelation.
Al Bukhari, a Muslim scholar of the 9th-10th century, and the most authoritative of the Muslim tradition compilers, writes that whenever Muhammad fell into one of his unpredictable trances his revelations were written on whatever was handy at the time. The leg or thigh bones of dead animals were used, as well as palm leaves, parchments, papers, skins, mats, stones, and bark. And when there was nothing at hand the attempt was made by his disciples to memorize it as closely as possible.
Zaid b. Thabit said: “The Prophet died and the Qur’an had not been assembled into a single place.” (p. 118, Ahmad b. `Ali b. Muhammad al `Asqalani, ibn Hajar, "Fath al Bari", 13 vols, Cairo, 1939/1348, volume 9, page 9)
Zuhri reports, 'We have heard that many Qur'an passages were revealed but that those who had memorized them fell in the Yemama fighting. Those passages had not been written down, and following the deaths of those who knew them, were no longer known; nor had Abu Bakr, nor `Umar nor `Uthman as yet collected the texts of the Qur'an.
“During the battle of Yamama, 450 reciters of the Quran were killed.” (The True Guidance, An Introduction To Quranic Studies, part 4 [Light of Life - P.O. BOX 13, A-9503 Villach, Austria], p. 47- citing Ibn Kathir’s Al-Bidaya wa al-Nibaya, chapter on Battle of Yamama).
Muhammad's child wife said this after Muhammad died:
"The verse of the stoning and of suckling an adult ten times were revealed, and they were (written) on a paper and kept under my bed. When the messenger of Allah expired and we were preoccupied with his death, a goat entered and ate away the paper."

As to the Taurat (Torah), Jewish scribes painstakingly copied it via a system of checking, double checking and adding each letter on each line. Any attempt to change something in the Torah would have resulted in immediate discovery and condemnation. And copies of the Torah from around the world agree exactly. Thousands of the Hebrew Old Testament manuscript copies are still available for textual criticism, ranging in age from the second century B.C. (Before Christ) to the eleventh century A.D. (After Christ).
