The Koran contains nothing original. All the stories expressed are copied from the Old Testament but the God of the Koran is cruel, angry and proud. The duties and rites of Islam are continuations of practices which the pagan Arabs had adopted. Therefore to say the Koran is miraculous book is wrong, the following is a list of stories copied from the Old Testament such as: Cain and Abel; Abraham ready to sacrifice his son; the fall of Adam; creations of the world; David praise of God; Jonah and the fish; Moses strikes the rock; Noah’s Ark; Solomon’s judgment and queen of Sheba. All are borrowed without being able to make a gross difference to show his revelation as the truly successor from a previous religion.
In other word Mohammad couldn’t show that he had the firsthand authority but Mohammad had more creativity in the intended dogma and destruction. Example his hate to women; he declared that Noah was unbeliever. Mohammad was confused about time and places of the prophets, he had heard nothing whatsoever as to the Genealogy of Jesus, His descend from David and his family relation to John the Baptist.
Mohammad made Mary the mother of Jesus as Mariam the sister of Moses and Aaron making such a big mistake that Jesus was at the same time of Moses book. In the Koran there is also an obvious confusion between Saul and Gideon (Compare Sura 2. 250 with Jude 7.5).
Mohammad had very little idea of Christian teachings, of what the Christian Church was in fact, he never did acquire very intimate knowledge of this, he therefore wounded the Christian Doctrine of the Trinity in three Suras.
Believe therefore in God and His Apostles, and say not, “Three” (Sura 4.169)
They misbelieve who say, “Verily God is the third of three” . . . The Messiah, the son of Mary, is only a prophet … and his mother was a confessor, they both ate food. (sura 5.77).
And when God shall say, “O Jesus son of Mary hast thou said unto mankind, Take me and my mrother as two Gods besides God?” (sura 5.116)
Mohammad made the Trinity consist of God, Christ, and Mary and seems clear this was Mohammad’s own view.
Remember: Hoopoe is the bird described in the Koran as the acting messenger between Solomon and the queen of Sheba.
