There is no proof that Monotheism was invented in 622 BC in Israel. We dont really know the dating of Avesta Gathas of Zoroaster who proposes Ahura Mazda but some date them 6000 BC. We dont really know the dating of the Vedas that proposes Na Thassya Prathima Asthi, Ikkam Ividithjam but are believed to date 3000 BC.
I understand that there is no clear archaeological proof for the existence of Abraham. If he did, thats definitely before moses who lived during the times of the pharaoh who lived at least 1300 BC.
Beyond dating the Sanaa manuscript via paleography it has been dated before 671 AD via radio carbon analysis with 99% accuracy and 646 with a 75% accuracy. The prophet Muhammed died in 632 AD. What canon are you talking about that was collected several centuries later? I think you are talking about something else. And I dont mean to start a different debate but you cannot compare this to the New Testament in the bible mate, the oldest bible manuscript is the Papyrus P52 which has been given a dating (Not definite) of 117 or later, that is also only through paleography. I would like to know what canon of the Quran you are talking about.
You are claiming that the Quran was translated from Hebrew and Greek.
Tell me where this was translated from, I have already posted this.
Divorce Law in the Quran
Chapter 65
 If divorce is imminent and you have decided to go ahead, there is an interim period.
 Within this interim period you must look after your spouse and it is decreed in order to give a chance of getting back.
 They are not to be sent out from the home unless they have committed some lewd act
 When the interim period exhausts, you can decide to remain together or get separated
 This has to be witnessed by two just people from amongst the man and woman (family or friends)
 If the lady has reached menopause or stopped menstruating, this interim period is three months
 If a pregnancy has occurred the interim period is until birth
 You cannot even try to coerce the spouse to leave the current home during this period
 The man is bound to provide for the woman by oath, according to his means
Chapter 33:49
 If at the time of divorce no intercourse has occurred, no interim is prescribed Quran
Chapter 2:226 upwards
 Interim period is 3 menstrual periods
 Reconciliation is encouraged but divorce between the same couple can occur only twice unless the woman marries and divorces another.
 The divorced mother is allowed to suckle the child for two years, no matter whos custody the child is under
 The man is responsible for both their clothing, sustenance and welfare unless they mutually agree to go their own ways
And where did he get this concept from?
Slavery
Most readers would find it astonishing to hear that slavery still exists in the modern world. Though the practice was abolished officially it is still very much alive. According to a study done by the International Labour Organisation the estimated number of slaves has increased from 12.3 million to 30 million since 2005. Slavery is not declining, in fact it is increasing.
Defining slavery
 Humans used, sold or bought as a commodity or property
 Imprisoned or kept by force with no freedom of movement
 Forced to work via some form of threat
 Forcefully acquired or owned by a master or employer, abused or under threat of abuse.
Slavery has been officially abolished since 1981 and the world at large, including some Muslims believe that Islam does propagate slavery. It is an erroneous view as you will find the Quran telling us that slaves are to be set free as a repenting act for a sin or crime you commit. If a billion Muslims follow the Quranic teachings and seek to set a slave free to redeem themselves, 30 Million slaves might see a hope of freedom. Many do find it silly to discuss slavery but slavery is very much alive, it is in the increase and needs attention. The ILO goes to the length of quoting 90$ as the average cost of a slave.
Freeing a slave is defined as an act of piety in the Quran.
Piety is not to turn your faces towards the east and the west, but pious is one who
 believes in God and the Last Day,
 and the angels,
 and the Book,
 and the prophets,
 and who gives money out of love to the relatives,
 and the orphans, and the needy, and the wayfarer, and those who ask,
 and to free the slaves;
 and who upholds prayer,
 and who contributes towards purification;
 and those who keep their pledges when they make a pledge,
 and those who are patient in the face of hardship and adversity and when in despair.
These are the ones who have been truthful, and these are the righteous. Quran 2:177
Very directly and clearly the Quran gives a formula to live by, which if someone has an argument against is imprudent.
As you can see, freeing slaves is part of a Muslims creed.
 Quran verse 4:92 says that if you kill someone by mistake (e.g. Motor Accident), you must free a slave and compensate the family. Compensating the family is for their wellbeing, freeing a slave is for your salvation. Imagine every Muslim in the world seeking to free a slave in case of an accidental death.
 Verse 5:89 ordains you to free a slave in case you had broken an oath or a promise. If you owe someone money and you break the promise of return, if and when you repent, it is not enough just to return that money. You must free a slave as an act of repentance.
 9:60 gives you freeing a slave as a duty amongst charity and relieving those in debt.
 The Quran articulates in this manner
Do you know which the better path is?
o The freeing of slaves.
o Or the feeding on a day of great hardship.
o An orphan of relation.
o Or a poor person in need.
 Quran 90:12-16
While translating the Quran from Hebrew and Koine Greek, and copying from the bible how did Muhammed maintain these things. (This is also from an older post)
The Quran has cited the word Day or Yawm in its singular form exactly 365 times from cover to cover. The singular word for Month or Shahr is mentioned exactly 12 times in the Quran indicating the year has 12 months. Writing a book with some 6,346 verses while containing the number of times you mention a particular word to represent a significant fact like 365 days a year in itself is impossible by human effort, especially 1400 years ago with no computers.
Quran mentions land 13 times and sea is mentioned 32 times. The ratio is 13:32 which is Land 28.8889% and Sea 71.1111% which is the exact land to sea ratio on earth.
He cant do it in a lifetime.
Also one my other arguments.
Haamaan or Haman was never cited in the bible nor any other document in the world other than Egyptian ancient lit in a language not deciphered until 1899 (I checked the date and stand corrected. Excuse mwa) with the discovery of the rosetta stone. An Egyptian tablet now in the Hof museum in Vienna shows how close Haman was to the Pharaoh. Bible does not record this. How did it only enter the Quran if it was plagiarism? Hope you understand my point. Also, this is a historical fact recorded. How did Muhammed know about "Haman" who's name was never known until 1899.
The Ipuwer Papyrus dating back to the middle kingdom if I am not mistaken over 1600 years ago. This papyrus describes the perils that the Pharaohs era went through as described in the Quran mostly accurately in the bible as well. This papyrus can be found in the Museum in Holland even now.
Quran records that the Pharaohs body will be saved from the water and you will find that his mummy was found preserved in the red sea in the 19th century. 1898. Wonder if that was a coincidence.
The drowning of the pharaoh is also described in the Egyptian Papyri No 6 found in the British Museum now.
Copying the bible he somehow managed to turn the tables on slavoury and divorce laws.
Being apparently illiterate and epileptic according to you Muhammed built a satellite to exactly measure the see to land ratio and managed to maintain the word count to depict it.
So Muhammed translated the Quran from Hebrew, Greek and deciphered ancient Egyptian before anybody in the world to know about Haman, not to mention that he did some archaeological digs when he traveled to Egypt.
Peace.
