Not "around" 634. The DJ dates itself to July, 634.

There are a couple of late 634 references (allegedly) by Sophronius however he does not do more than mention the Saracens and this is hardly news....unlike the DJ which uses the word "prophet."
Now, whether or not you had ever heard of the DJ is irrelevant. You correctly cited its date as the earliest Byzantine reference so whatever list you were using obviously knew of it. But, as I said, you did not follow up on it because there is no way that any muslim would. Your story is that Mo was dead by the time it was written and I don't expect you to give up your stories for history.
Quote:[Jacob, himself a convert, wrote to encourage Christian faith in Jews of Carthage, forcibly converted in 632, in a tract that was completed before "the thirteenth of July in the seventh indiction," i.e. 634, when Jacob left Carthage
