وهو أي خبر الرسول يوجب العلم الاستدلالي
The messenger's report yields inferential knowledge.
The inference has stages: the validating miracle supports prophethood; an authentic attribution establishes that the messenger issued a report; and the truth of the message follows from his established authority. Understanding the report and establishing its truth are distinct tasks.
Inferential knowledge is reached through an appropriate proof and sound reflection, whereas necessary knowledge may arise without arranging such a proof. Their routes differ, even though both may yield firm certainty.
