This quote is amusing, but it has always made me wonder... if this is a good translation, then did Avicenna really not understand the law of non-contradiction? Because one who denies that p^~p is a contradiction does not necessarily assert that p and ~p are the same.
What does one mean when one denies the truth of ~(p^~p)? I would guess the person means that this statement is not always true, and thus there exists a p for which this statement is false. Which would mean that there is a p for which p and ~p are simultaneously true.
Of course this doesn't mean that the person believes that "to be beaten is the same as not to be beaten", but it's an amusing quote.
