In this episode Al Fadi and Dr Jay recap the first eleven claims; in conclusion : every reference to Mohammad in these claims place him in the wrong place and probably refer to other  Muhammads = " the praised ones ".  Then they discuss claim #12 The Ashtiname Letter, which was supposed to be written by Mohammad or Ali to the monks of St Catherine's Monastery, promising protection and other privileges. This turned out to be a fraud written by the monks of the monastery to protect themselves from the Marauding  Muslims all around them.
