No only the Koran. Keep up , if one book is in question , one which originated from another, then the others needs to be questioned first.
Which 3 books are you referring to?
You are assuming that illiterate Saudi Arabian terrorist pedophile thief "copied" the two books that came before him properly.
Mohammed did not record the recitals. Others learned to recite them as well, often with slight differences. Mohammed did not object to some of them.
His followers before they died tried to wrote or have them written down on scraps of anything from leaves to bark to leather and types of vegetable paper. Those were all collected over time and put together like a jigsaw puzzle. The the sura were listed from longest to shortest, not in the order they were given by Mohammed. Over the next hundred and fifty years there were many edits before a final codex was set. There are differences between sunni and shiite versions as well as a dozen or so variations in readings that also change meaning, tense and emphasis. In other words there are many versions and translations, not one absolute god given perfection that was unchanged from the angel to the modern form.
Any text or story that get passed word of mouth over generations before being written down will likely have some variance.
Mohammed even gave verses that were later infamously removed but the change was recorded in the hadiths.
The hadiths also do now agree on many event or point in the life of Mohammed.
