Ans.Get hold of a Quran.
Ignore all sura's written about things after 624ad.
Ignore the fantasy of Hagar, Ishmael & Abraham ever being at Mecca.
Replace Allah with YHWH.
There you have it.
The original Quran - book of T'ubah - the Jewish book of rules for the ishmaelites.
The book muhammad preached on behalf of the red sea Jews and Jewish aligned Medina tribes.
Before he went heretic, and with Abu Bakr of Mecca, cooked up an apostasy of it.
Muhammad originally demanded (in 62ad) to be a prophet equal to Moses with allAh included as a minor (pagan) deity to keep the quraeesh on side.
When the jews outcast Muhammad in 624, he elevated Allah the moon god of the qureesh to replace YHWH as supreme god. And he himself replaced Hubal the stone god idol / as allahs
messenger. Muhammad then formed a secret treaty with the non Jewish pagan Arab tribes of medina to attack his previous sponsors.
The Quran itself tells you this.
No one had to read or write to understand and then synthesize in a pagan god over a well established bit of script.
So no miracle, nothing godly, just a tacky evident plagarisation that any illiterate could have done, esp one well exposed as Muhammad was - he being a keen student and missionary of the book of T'ubah and Jewish Ishmaelite faith for years before.
Please do the needful and post a copy of "Mutilated Quran" for every one to see.
It is YOU who needs to do homework and not us!!
Every one can say what he wants and wishes, but proofs are needed when you are serious.
Sitting on a couch I can also web any thing I like.
Act and not merely claim my dear fellow!!
