وهذه الأربعة أربعة أخرى تقابلها.
These four have another four classes corresponding to them.
1. Khafi versus zahir: the ordinary sense is clear, but application to a particular case is hidden.
2. Mushkal versus nass: the wording itself calls for closer interpretive reflection.
3. Mujmal versus mufassar: the speaker's clarification is needed to settle the intended meaning.
4. Mutashabih versus muhkam: obscurity reaches its greatest degree.
The point is a graded increase in obscurity, not four interchangeable words for ambiguity.
