المحكم: ما ازداد قوة على المفسر بحيث لا يقبل التأويل والتخصيص والنسخ أصلاً.
Muhkam is wording still stronger than mufassar: it admits no reinterpretation, specification, or abrogation at all.
Mufassar already makes the intended meaning definitive through clarification, but the textbook preserves the theoretical possibility of naskh in the period of revelation. Muhkam excludes even that possibility.
This higher status is not simply the result of adding more emphatic words. The nature of what is being asserted is also central to its immunity from alteration.
