Is it necessary to declare disbelief against one who legislates a law and constitution for the state that is not from the legislation of Allah?

The questioner:
He says: Honorable Shaykh, may Allah grant you success, if one legislates a law and constitution for the state, all of which is not from the legislation of Allah, is it necessary to declare him a disbeliever, or do we proceed to detail his intention?

The Shaykh:
First, delving into these matters that stir up strife and this kind of trouble is not permissible except for scholars and even then only when there is a need. As for what stirs up strife, spills blood, and incites people, that is not permissible. Judging people and rulers is a matter that belongs to the people of knowledge and insight.
So it is not for those who are seeking knowledge or the common people, and all people entering into this topic, for this causes confusion and causes harm. They may judge people without evidence and not settle matters. This requires scholars. I do not see that those seeking knowledge and beginners should enter into these matters. Yes.

The presenter:
He says: Honorable Shaykh.

The Shaykh:
And they know them, yes. But that they argue about them and judge some people, that is not permissible for them. This is the exclusive domain of the people of knowledge. Yes.
