Have you not known-O Messenger-the matter of those hypocrites who claim faith in what was sent down to you-and it is the Qur'an-and what was sent down to the messengers from before you, while they intend that they judge in the decision of the disputes between them to other than what Allah legislated of the falsehood, while they were surely commanded that they disbelieve in the falsehood? And Satan intends that he distance them from the path of truth, a far distance. And in this verse is evidence that the truthful faith, necessitates the submission to the law of Allah, and the judging by it in every matter of the matters, so whoever claimed that he is a believer and chose the judgment of the Taghut (false god/judge) over the judgment of Allah, then he is a liar in his claim.
