General statements. One just cannot engage properly with just general statements. Most of your post above is just general comments.
I said you are wrong because you were wrong. I would suggest you dont make statements you dont understand. If you want, just ask.
Also, I didnt stop saying you are wrong. I said certain things which of course you have not addressed. Maybe I will cut and paste so that you can read again rather than making things up. Below.
he Qur'an was written down in the 7th century and manuscripts alone can cover the Quran within the 1st century Hijri. So this "couple of centuries later" is a statement repeated by many just based on hearsay based on hearsay.
So can you provide evidence to the satanic verses other than just saying "Ibn Ishaq, Ibn Saad, atthabari? Attabari repeats Ibn Ishaqs narration, and through the history of islamic conservative scholarship people have rejected Ibn Ishaq as dubious. I think non-muslims like you are more dogmatically in love with some of the dubious sources in literature than the muslims themselves.
