وإن كان منكرا وجب توكيده بحسب الإنكار
When the hearer denies the judgment, the report should be strengthened to suit the degree of denial.
The inkārī mode may appear as “إِنَّ الطَّالِبَ لَنَاجِحٌ” — The student is most certainly successful. This combines “إِنَّ” with the emphatic lām.
The rule is proportionality: stronger resistance can warrant a stronger assertion. Piling up emphasis without communicative need, however, does not automatically improve rhetoric.
