When a wrong against a person’s honor is of a kind for which no retaliation [is available] (1), such as a false accusation of fornication or another offense, the punishment is the prescribed penalty when it involves such an accusation and discretionary punishment otherwise.
As for the prescribed penalty (2) for false accusation of fornication, it is established by the Quran, the sunnah, and consensus. Allah Most High says:
“Those who accuse chaste women and then fail to produce four witnesses—flog them with eighty lashes and never thereafter accept their testimony. It is they who are defiantly disobedient. (4) Except those who subsequently repent and mend their ways; surely Allah is All-Forgiving, Most Merciful.” [al-Nūr: 4–5] (3).
(4) This penalty—the prescribed penalty for false accusation of fornication—is a right belonging to the person falsely accused. By agreement of the jurists, it may therefore be enforced only at his request. If he waives it, it lapses according to the majority of scholars, including Mālik, al-Shāfiī, and Ahmad in the position most widely reported from him, because it is predominantly a right owed to the individual, as in cases of retaliation and property rights.
