Islamic believe Quran is perfect in every way. They believe that the Bible, or New Testament to be more exact, is corrupt.

Old Testament completed by 150 B.C. for sure.
New Testament completed around 100 A.D.
Quran completed in 7th century.

In the Quran:
-Jesus was born in Jerusalem,
Bible:
-Jesus was born in Bethlehem.
Quran:
-Pharaoh ordered Haman to build a tower reaching into Heaven to speak to Moses' God.
Bible:
-Haman in book of Esther/5th century B.C. in Persia (Iran)
-Pharaoh: 15th/13th century B.C. in Egypt
-Tower of Babel: pre-history/Genesis 11(after flood)in Babylonia (Iraq)
Quran:
-Pharaoh also threatens to crucify his magicians.
Bible:
-Crucifixion was in 2nd/1st century Rome
-Pharaoh never crucified anybody

Jewish Folklore (Arabian)
Sura 7:163-166 Sabbath Apes (Jews didn't observe Sabbath-God turned them into apes)
Sura 18 The Cave- a group of devout men retreat from corrupt society. God puts them to sleep for 309 years (Rip Van Winkle)
Sura 46:29-35, 72 Jinn(genies/spirits) like Bible's angels.

Islamic take on Christianity:
Accepts:
-Moses, Jesus, Abraham, as well as all O.T. prophets to be prophets of Allah.
-Virgin birth of Jesus
-Second coming of Jesus before the end of the world.
Doesn't accept:
-Jesus never claimed to be God's son. God has no son.
-No Trinity
-no crucifixion, resurrection

More Jewish than Christian
