When a Companion not known to draw on Israelite narratives relates detailed matters about the beginnings of creation or earlier prophets that are inaccessible to normal observation and cannot arise from ordinary ijtihād, critics may examine whether the report carries the status of constructive marfūʿ.
Illustrative category: a particular unseen event involving an ancient community, or a detailed claim about creation not open to independent discovery. The category does not turn every historical story into a verified Prophetic report.
The chain’s narrators, continuity, and other reliability conditions are still assessed separately. Constructive attribution and authentic transmission are different questions.
