The Quran is at the heart of Islam. If its claims can be substantiated, then Islam is true, and all opposing religious claims, including Christianity, and Judaism, are false.
Of course the claims that the Muslims make for the Quran are, that the Quran is errorless sura 18:1, and there is a copy of it in a table in heaven preserved sura 85:21-22.
The Quran also claims that, "The revelation of this book is from God, The exalted in power, full of wisdom. It is we who have revealed the book to thee in truth" (sura 39:1-2).
Muslim commentators say that the Quran is the final revelation from God (see for more details, Geisler's book, Answering Islam, p.179-80).
Muhammad also makes the claim that, "Can they not consider the Koran? Were it from any other than God, they would surely have found in it many contradictions" (sura 4:84).
So according to the Quran, if there is contradictions in this book, then IT IS NOT THE WORD OF GOD!
Muhammad just helped us dig the grave for the Quran. THE QURAN IS LOADED WITH CONTRADICTIONS!
Let's examine some of the contradictions in the Quran.
The Quran differs whether a day is 1000 years, or 50,000 years see sura 32:4, and 70:4.
On the day of Judgment the infidels attempt to conceal something from God Sura 6:22-23. But in Sura 4"45 we see that the infidels don't attempt to conceal anything.
In sura 56 the people who follow Muhammad will be "a crowd of the former, and few of the latter generations" verse 14. But in verse 39 it says that the people of Muhammad will be "a crowd of the latter generations." Other translations have "multitude" as the word instead of "crowd." so which one is it, a few of the latter, or a crowd?
Commenting on the Exodus, God told the Israelites, "And it was said to them, "Dwell in this city, and eat therefrom what ye will, and say "Hittat" (forgiveness) and enter the gate with prostration's; then we will pardon your offences, we will give increase to the doers of good" (7"162).
Now look at this verse about the same subject: "And when we said, 'Enter this city, and eat therefrom plentiful at your will, and enter the gate with prostration's, and say, "Forgiveness," and we will pardon you your sins, and give an increase to the doers of good:' (sura 2:55). Now if the Quran is without error how do you explain the difference of these two statements? This is god talking to the Israelites, and both times God is quoted wrong. One could understand if this was two people witnessing what was going on and wrote it down, but this is not the case. the Quran is dictating what happened in the past.
5. In sura 22:40-41 God says that people who are persecuted because of believing in God can take up arms and defend themselves. But in Sura 66:9, God commands to make war with people who don't believe.
6. Because Judaism and Christianity were divided into sects, the Quran says that they were not of God, see Suras 30:30-32; 42:11-15.
Yet Islam is divided into many warring sects, and therefore Islam is false as well, according to the Quran.
7. In sura 11:45 we read that Noah's son "was among the drowned," that is he died in the flood. But sura 21:76 we read that God saved "all his kinsfolk from the great calamity..."
8. At first Muhammad was nice to the Christians and the Jews. The Quran says that if they try to convert you to "unbelief" to "forgive them." (sura 2:59, 103). Then Muhammad says to slay all unbelievers (sura 5:55;9:29-30;66:9).
9. There are conflicting views about how many days of creation. In sura 41:8-11 the Quran says that it took 8 days to create everything (4 days + 2 days + 2 days = 8 days). but it only took 6 days according to the Bible (Gen. 1:31). Also in the Quran in suras 7:52, 10:3; 32:3-4 it says God created everything in 6 days. Then it says that everything was created in a twinkling of an eye, see Sura 54:50 So the Quran conflicts with itself and the Bible.
10. In the creation of Adam, God told his angels to worship Adam, see sura 2:32. This breaks his own law , that you should only worship God, see sura 2:77
All over the Quran we read that God is AN ABSOLUTE ONE. Sura 112 says, "he is God alone: God the eternal!He begetteth not, and He is not begotten; and there is none like unto him" It also says that, "And they say God has a son.' No! ..sole Maker of the heavens and the earth!" (sura 2:111; 4:169). Problem is why does the Quran say that, "Have WE not made the earth a couch? And the mountains tent stakes?...And built above you seven solid heavens" (sura 78:8, 11).
"And as to the earth, WE have spread it out..." (sura 50:7).
"WE have not created the heavens and the earth and whatever is in between them in sport: We have not created them but for a serious end" (sura 44:39).
Question: If God is alone, has no son, sole maker of all things, they deny the Trinity saying God is one not three (see sura 5:77). So the question is who is "WE" IN THESE VERSES? Not Just in these verses, but this is all over the Quran. it talks about how "we parted the sea," and "we made a covenant with Israel." Some Muslim scholars say that this is the plural of majesty, like in Genesis 1:26, where God says "Let Us make man in Our image, after Our likeness." Problem is, recently historians are starting to discover that the plural of majesty was never known among the Hebrews, and it came to be during the Medieval times of the kings of England, in Europe. So who is "we?" Was Muhammad claiming divinity, even though he denied it?
11. To drink wine (sura 16:67; 2:219:4:43), or not to drink wine, (sura 5:92)?
12. Did Jesus die (Sura 19:33; 3:55), or not? (Sura 4:157-158).
13.One part in the Koran God says that you need a mediator to talk to him (Sura 42:51-52), and that it "biffitteth not a man," meaning all men. In another place it says that Moses spoke directly to God, (Sura 7:143; 4:164).
14. In one place it says that Abraham was not an idolater (Sura 3:67; 6:62). but in another place you see Abraham committing idolatry (Sura 6:75-78).
15. In one place Muhammad is told not to bother, in converting unbeliever (Sura 2:6-7), for their fate is sealed. In another place Muhammad is told to attempt their conversion by peaceful means anyway (Sura 24:54).
16. Muhammad first said that it does not matter where you are facing to pray because God is everywhere (Sura 2:109). Then he changed his mind and said that we should pray towards Jerusalem, and then changed his mind again and said we should face Mecca (Sura 2:119-121, 138-144). And this contradiction is all in the same chapter.
17. Finally, one huge contradiction in the Quran that actually is embarrassing to the Muslims. The Quran claims that the book is written in pure Arabic see suras 12:2; 13:37; 16:105; 41:44. Robert Morey says: "The Quran is not perfect Arabic. It contains many grammatical errors, such as suras 2:177, 192; 4:162; 5:69; 7:160; 13:28; 20:66; 63:10. etc..." (Islamic invasion, p.119).
In his book, The Foreign Vocabulary of the Quran, Authur Jeffery documents the fact that the Quran contains over 100 foreign (non-Arabic) words. There are Egyptian Hebrew, Greek, Syriac, Akkadian, Ethiopian and Persian words and phrases in the Quran.
Back to Mohammed's question, "Can they not consider the Koran? Were it from any other than God, they would surely have found it many contradictions." How would you answer Muhammad, if he were still alive today?
