Sayyiduna al-Nu'man bin Bashir (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever gives as many lashes as a prescribed punishment for an offence other than a prescribed punishment is among the transgressors."
Al-Tabarani recorded it; its chain contains Muhammad bin al-Husayn al-Faddad and al-Walid bin Uthman, the maternal uncle of Mis'ar, and I do not know either of them; the rest of its narrators are thiqat (trustworthy).
