So I sent you three links to two different books with links to each book from archive dot org and I do not know if they are the full books or incomplete

One is one link to the book you listed

Early Islam A Critical Reconstruction Based On Contemporary Sources ( Karl Heinz Ohlig)

The other is two links to the book

The Syro-Aramaic Reading of the Koran
by Christoph Luxenberg

You will have to go through my multiple comments to find both
