judging by the Sharee'ah in aqidah is greater than judging to it in the [other] affairs

Shaykh Salih al-Fawzaan wrote in his book (إعانة المستفيد بشرح كتاب التوحيد), an explanation of Kitab ut-Tawhid, the following, in deconstructing and annihilating the foundation of the da’wah of these people (p. 151):

فما يقوله دعاة الحاكمية اليوم ويريدون تحكيم الشريعة في أمور المنازعات الحقوقية، ولا يحكمونها في أمر العقائد، ويقولون: الناس أحرار في عقائدهم، يكفي أنه يقول: أنا مسلم، سواء كان رافضيا أو كان جهميا أو معتزليا، أو . أو . إلى آخره، “نجتمع على ما اتفقنا عليه، ويعذر بعضنا بعضا فيما اختلفنا فيه” هذه القاعد التي وضعوها، ويسمونها: القاعدة الذهبية . وهي في الحقيقة: تحكيم للكتاب في بعض، وترك له فيما هو أهم منه، لأن تحكيم الشريعة في أمر العقيدة أعظم من تحكيمها في شأن المنازعات الحقوقية ، فتحكيمها في أمر العقيدة وهدم الأضرحة ومشاهد الشرك، ومقاتلة المشركين حتى يؤمنوا بالله ورسوله، هذا أهم

“So what the callers of al-Haakimiyyah do today, and they desire to make the Sharee’ah the reference point of judgment in the affairs of dispute pertaining to the rights (of the people), but do not judge to it in the affair of beliefs, and they say, “The people are free in their beliefs, it is sufficient that he says, ‘I am a Muslim’, whether he is a Raafidi, Jahmee, or Mu’tazilee”, and so on, [and that], “We will unite on that which we agree upon and excuse each in that which we differ over”, this is a principle that they have devised, and they call it “The Golden Principle”, and it is in reality judging to the Book in some (affairs) and abandoning (judging to it) in that which is more important than (those affairs).

[This is] because judging by the Sharee’ah in aqidah is greater than judging to it in the [other] affairs of the disputes pertaining to the rights (of the people). And thus, judging to it in the affair of aqidah, destroying the tombs, and the places of Shirk (shrines, tombs), and fighting the Mushriks until they believe in Allaah and His Messenger, this is more important.”
