Anyone researching and investigating the origins of the Quran will find that a lot of people were involved in its compilation and construction.
Unknown to the vast majority of Muhammadans, and buried deep inside the Quran, Ahadith and Sirah, there is copious evidence to reject, out of hand, the contention that the Quran is the creation of Allah.
Making Allah the author of the Quran, is the prime and most groteque lie and deception that was ever perpetrated upon the human intellect for more than 1400 years.
One can say with a great measure of certainty, that the Quran was either composed or inspired and written by a few other individuals. The most notable among them were:
Imrul Qays- an ancient poet of Arabia who died a few decades before Muhammad's birth
Zayd b. Amr b. Naufal- an 'apostate' of his time who preached and propagated Hanifism
Labid- another poet
Hasan b. Thabit- the official poet of Muhammad
Salman - the Persian-Muhammad's confidante' and an advisor
Bahira- a Nestoraian Christian monk of the Syrian church
Jabr- a Christian neighbour of Muhammad
Ibn Qumta- a Christian slave
Khadijah- Muhammad's first wife
Waraqa- Khadijah's cousin brother
Ubay b. Ka'b- Muhammad's secretary and a Qur'an scribe
Muhammad - himself
Bahira
Bahira was a Nestorian Christian monk who lived in Sham (Syria). His Christian name wasSergius or Georgius. It is believed that he was expelled from the monastery for certain offences. To expiate it, he set out on a mission to Arabia.
In Mecca, he met Muhammad, became intimate with him and stayed with him. He had confidential conversations with Muhammad, in which he surely told Muhammad many facets of Christianity. The verses in the Quran dealing with Christianity must have emanated from Bahira, the monk. Muhammadsimply re-wrote them with the help of his Quran collectors or scribes.
It is believed that the Quranic verses on the Psalms of David were actually the contribution of Bahira.These verses are:
4.163 We have sent thee inspiration, as We sent it to Noah and the Messengers after him: we sent inspiration to Abraham, Isma'il, Isaac, Jacob and the Tribes, to Jesus, Job, Jonah, Aaron, and Solomon, and to David We gave the Psalms [Zaboura].
17.55 And it is your Lord that knoweth best all beings that are in the heavens and on earth: We did bestow on some prophets more (and other) gifts than on others: and We gave to David (the gift of) the Psalms[Zaboura].
21.105 Before this We wrote in the Psalms [al Zabouri], after the Message (given to Moses): My servants the righteous, shall inherit the earth."
[In fact, the Dictionary Islam (p.698) writes that the last quoted verse (21.105) is a direct quote from Psalm 37.29]
Psalm 37:29 " The righteous will inherit the earth and dwell forever upon it"
Here are some sample verses which most likely were contributed by Bahira:
2:101 And when came to them an Apostle from Allah confirming what was with them a party of the people of the Book threw away the Book of Allah behind their backs as if (it had been something) they did not know!
***Even when Muhammad confirmed the previous scriptures, the Jews and the Christiansrejected him ***
2:113 The Jews say: "The Christians have naught (to stand) upon"; and the Christians say: "The Jews have naught (to stand) upon." Yet they (profess to) study the (same) Book. Like unto their word is what those say who know not but Allah will judge between them in their quarrel on the Day of Judgment
*** The Quran implies that the Jews and the Christians quarrel with each other even though they study the same book.
Of course the Quran is, as usual, WRONG, since the Jews and Christians have no quarrel with each other regarding the Hebrew Bible but ONLY regarding the New Testament which theJews do not accept since it is not part of the Divine Revelations at Mount Sinai***
2:139 Say: Will ye dispute with us about Allah seeing that He is our Lord and your Lord;that we are responsible for our doings and ye for yours; and that we are sincere (in our faith) in Him?
*** This verse implies that the 'Islamic', the Jewish and the Christian God is the same God,do not argue on this; Allah will reward each group according to their deeds…
In reality, Allah was never the god of Israel or of Jesus since Allah was ONLY the name of the rock god of the Ka'ba, the Black Stone***
3:23 The Jews and the Christians are invited to believe in the Book of Allah to settle their disputes...
*** The Quran has nothing either equal to or superior to anythnig that it, theQURAN, had PLAGIARIZED, PLUNDERED, PIRATED and/or PERVERTED from the BIBLE, to justify that the People of the Book should believe in it or to use it as a GUIDE ***
3:78 Some Jews and Christians twisted their scriptures and passed them as Allah's messages…
