وَلَيْسَتْ حَقِيقَةُ التَّصْدِيقِ أَنْ تَقَعَ فِي الْقَلْبِ نِسْبَةُ الصِّدْقِ إِلَى الْخَبَرِ
The reality of assent is not simply that the mind associates truth with a report.
A person can understand that a report claims something happened, or consider its truth hypothetically, without accepting it. The account of faith therefore includes reception and acknowledgment, not just representation of a statement's content.
This distinction addresses the objection that merely recognizing the truth of a prophet while deliberately resisting or denying him should count as faith. Bare recognition is not treated as adequate assent.
