Al-Nawawī records disagreement over **future transmission after a person who deliberately lied in hadith has genuinely repented**. His preferred and apparently stronger position allows eventual acceptance after proper repentance, as with other serious transgressions, provided reliability is established. The opposing position permanently refuses later transmission because deliberate false attribution to the Prophet ﷺ warrants particular severity and deterrence. Neither view turns an earlier fabricated report into authentic Prophetic speech.
Qāḍī ʿIyāḍ also distinguishes cases of untruthfulness in ordinary conversation, material error or confusion, and intentional false reporting in hadith. A demonstrably mistaken transmitter is not automatically a fabricator. For a proven offender, sincerity of repentance and subsequent accuracy and integrity remain evidentiary questions; accepting an individual later report is not automatic merely because repentance is claimed.
**Application:** Repentance may change the narrator’s future standing according to the scholarly positions and the evidence; it cannot retroactively convert a report knowingly invented before repentance into a genuine hadith.
