He knows quite a lot abot the Outer Gates and outsiders, even specific spells to use against them and what wards to check in order to get warning of their arrival. Since even knowledge of the Outer Gates and outsiders is against the Law, that's 7th law violations right there.
In addition, Rashid can tell the future. Not only does he get premonitions about it but he has shown the ability to predict the whole mess during Proven Guilty down to the totally unexpected arrival of several Senior Council members and Michael with enough precision to withold his vote and control the trial's outcome through said future information. He has also shown the ability to see the future of a person with precision enough to know whether Dresden could succeed or not during the whole Turn Coat debacle, including calculating the outcome of changing circumstances after warning Dresden of his impeding failure. That's both outright knowledge of the future and using knowledge of the future. 6th law violation right there.
So, Lawbreakers 6th and 7th. This does not mean the guy is a slave to his nature or totally twisted by the magic he uses; he might be tempted but just like any other wizard with positive refresh, he has free will. Just like Dresden, despite being a pretty serious 1st Lawbreaker.
Simply POSSESSING knowledge of the Outer Gates is not, and could not, be against a (reasonably) commonly known Law, as merely knowing of the Law, then, would violate that same Law.
Even possessing knowledge from BEYOND the Outer Gates is not in itself a violation of the (metaphysical incarnation of the) Law (though it'll likely be enough to get you sentenced by the Council). The Law prohibits SEEKING knowledge (and Power) from beyond the Outer Gates.
Interpretations of what constitutes a violation of the 6th Law are even less clear, and definitive statements such as those made above should be qualified as being applicable to a particular 'table' or group.
