«مَا أَذْكُرُ هَذَا»
“I do not recall this.”
Such a statement does not logically negate the possibility that the teacher narrated the report in the past. Old age, the passage of time, or ordinary lapse of memory may explain the present failure of recall. It should therefore not be treated as equivalent to a categorical denial.
Distinguish two cases:
1. “I certainly did not narrate this” — explicit negation of attribution.
2. “I do not recall narrating it” — inability to remember the act.
In the second situation, a reliable student's positive testimony need not be defeated by the teacher's forgetfulness; further conditions of acceptance still matter.
