Mario Puzo's "Godfather" was the original quote.
The reference in the Startrek movie that it was from an Arab Prince was fictitious.
It sounds like you would find it in Sun Tzu, but its not. If you find it there it was put in there by the translator well after the Godfather movie came out. I know its hard to believe that someone this century could come up with a quote like that no one else has said, but it you do some google searches you well see that its true.
The quote came from Mario Puzo's book the "Godfather".
