Did you even open the link that I just posted? I am talking about the link that didnt work in my first post. The topic of the paper is the analysis of another version of the treaty written by a greek orthodox patriarchate, not about jews and in there it mentions that al tabari version is the most popular. If you dont know who al tabari is, he is a very well known islamic scholar who lived in the 9th century and is the author of many great works, just google him. The author of the version that you posted is a scholar who was born nearly hundred years after al tabari and is more known for his philosophy, so "most of them aren't even Muslim" doesnt apply here.
