"The one who leaves the Hukm by what Allaah revealed; if he makes the general judgements with the fabricated laws, does he disbelieve? And is there a difference between that and the one who judges with the Sharee'ah but then he opposes the Sharee'ah in some of the matters due to desire or bribery or other than that?"

So he answered, "Yes, it is Waajib to differentiate between them. There is a difference between the one who throws away the Hukm of Allaah, jala-wa'ala and replaces it with the judgements with the laws and the judgement of mankind. This is Kufr, which takes one outside the Milla of Islaam. But the one who is Multazim (i. e. religiously committed) upon the Deen of Islaam except that he is disobedient and a Thaalim by following his desires in some of the Ah'kaam and goes after a benefit from the Dunyah, while accepting that he is Thaalim with this, then this is not Kufr, which takes you out of the Milla. And whoever sees the Hukm with the laws to be equal to the Hukm of the Shara' and makes it Halaal, then he also disbelieves with the Kufr that takes one outside the Milla, even if it is in one instance."
