اختلف القائلون بانحصار الخبر في الصدق والكذب في تفسيرهما
Those who held reports to be exhaustively divided into true and false differed over the interpretation of these categories.
Ḥaṣr means that every report must fall under one of the two classifications. The majority and al-Naẓẓām provide distinct binary tests; al-Jāḥiẓ’s combined conditions leave mixed cases between them.
The difference is substantive. One report may be true under one criterion, false under another and intermediate under a third. Always identify the operative definition before classifying a disputed example.
