"Thirdly: The one who is attributed to Islaam and knows its laws and then fabricates for the people, laws and makes them an institution for them to conduct themselves by and to take their judgements to and he knows that it opposes the laws of Islaam. Then he is a Kaafir out of the Milla of Islaam. And like that is the Hukm concerning the one who orders a committee or committees to be formed for that and the one orders the people to take their judgements to these institutions or laws or makes them take the judgements to them, while he knows that they oppose the Sharee'ah of Islaam. And like that is the one who judges with it and implicates it upon the matters and the one who obeys them in these judgements out of his own choice, while he knows that it opposes Islaam. So all of these are partners in their turning away from the Hukm of Allaah."
