Not so fast, Apple Pie. I must apologise though, I might only be able to reply on weekend.
Liberate has given the link (I am not sure if that is the Gospel of Thomas the Israelite or the Arabic Gosepl of Infancy). But scholars, even those who are very much against Islam, said that the original Gospel of Infancy does not date from the Prophet's time:
The style of the Arabic of this apocryphal Gospel, however, is so bad that it is hardly possible to believe that it dates from Muhammad's time.(Rev. W. St. Clair Tisdall, The Original Sources of the Quran, Chpt IV)
Loki even made a ridiculous assumption:
since the gospels i mentioned are coptic gospels (egyptian/syrian) and all the gospels muhammed used were coptic gospels in wich he copied from...
I have never seen any scholars, even those anti_islam, gave an open statement like that. Surely, Loki has a proof before he could make such claim?
Liberate said
I suspect regardless of how much proof or evidence we give you, you will give us the standard muslim rhetoric of GIVE ME MORE PROOF.
Of course! You make such a strong accustaion and you want to escape from giving a PROOF? Surely, the Bible does not teach you that.
Again, there is NO PROOF that the Prophet copied from the Gnostic source.
