A known example concerns a report about judgment on the basis of a witness and an oath through the chain Suhayl ibn Abī Ṣāliḥ → his father → Abū Hurayrah. ʿAbd al-ʿAzīz ibn Muḥammad al-Darāwardī received it from Rabīʿah ibn Abī ʿAbd al-Raḥmān, who had transmitted from Suhayl.
The sequence matters: al-Darāwardī preserved the route through Rabīʿah and later asked Suhayl about the narration. Suhayl initially did not recognize it.
The case therefore tests the distinction between categorical rejection and a lapse of memory. The next step shows how the prior transmission was carried back to Suhayl.
