Germany already had Islam; NAZISM. A death cult which saw Hitler, like Muhammed, a prophet of Providence. Churchill knew this too, calling Mein Kampf the “new Koran of war.”
From Wikipedia...
Hitler regarded Arabs as an inferior race[232] and that the relationship he had with various Muslim figures was more political than personal.[232] During a meeting with a delegation of distinguished Arab figures, Hitler learned of how Islam motivated the Umayyad Caliphate during the Islamic invasion of Gaul and was now convinced that “the world would be Mohammedan today” if the Arab regime had successfully taken France during the Battle of Tours,[232] while also suggesting to Speer that “ultimately not Arabs, but Islamized Germans could have stood at the head of this Mohammedan Empire.”
