Qisas — The Law of Proportional Retaliation: Justice, Mercy, and the Right to Forgive

The Two Parts of the Quranic Framework

The Quran’s treatment of qisas always presents both elements together:

Part 1 — Equal Retaliation: “And We prescribed for them therein a life for a life, an eye for an eye, a nose for a nose, an ear for an ear, a tooth for a tooth, and for wounds is legal retribution.” (5:45)

This is the justice dimension — the killed person’s family has the right to demand the killer’s life; the injured person has the right to demand equivalent injury to the perpetrator. This principle prevents both private vendettas (the victim is limited to equal retaliation, not escalation) and state impunity (the state cannot simply pay off victims).

Part 2 — The Encouragement to Forgive: “But whoever overlooks from his brother anything — then there should be a suitable follow-up [i.e., payment of diyya] and payment to him with good conduct.” (2:178)

The higher virtue is forgiveness — either in exchange for diyya (blood money) or freely. The Quran frames forgiveness not as weakness but as a divinely-encouraged alternative that earns merit.

The Three Categories of Homicide

1. ‘Amd (Intentional murder): The perpetrator intentionally killed with a weapon intended to kill. Qisas applies — the victim’s family may demand execution, accept diyya instead, or forgive freely.

2. Shibh ‘Amd (Quasi-intentional): The perpetrator intended to harm but not to kill, using something that would not normally kill (hitting someone with a hand or stick). Death resulted but was not intended. No qisas; the family receives diyya mughallaẓa (heavy blood money).

3. Khata’ (Unintentional/Accidental): No qisas; only diyya and kafara (expiation — fasting for 60 days or freeing a slave). “And it is not conceivable for a believer to kill a believer except by mistake.” (4:92)

Conditions for Qisas to Apply

For qisas to be applicable (the majority Sunni view):

• The killing must be ‘amd — proven intentional
• The perpetrator must be a mukallaf (adult, sane)
• The victim cannot be the perpetrator’s child or descendant (parent-child exception across most schools)
• The killing must be without right (not in legitimate self-defense or just war)

The Four Witnesses Rule: For capital punishment under qisas, the Islamic evidentiary standard is the highest in the legal system — four eyewitnesses, or confession. The purpose of these stringent conditions is to make application rare, reflecting the prophetic: “Ward off punishments from Muslims as much as you can — if there is an escape from a punishment, leave it, for it is better for the imam to err in pardoning than to err in punishing.” (Tirmidhi)

The Right of Forgiveness — The Elevated Choice

“But if he is forgiven by his brother, then there should be a fair follow-up and payment in a good manner. This is an alleviation from your Lord and a mercy.” (2:178)

The right of forgiveness belongs to the victims’ family (awliya’ al-dam — the blood-heirs). They have three options:

1. Qisas: Demand equal retaliation
2. Diyya: Accept financial compensation instead
3. ‘Afw (Pardon): Forgive freely, with no payment demanded

The Islamic tradition elevates option 3 as spiritually highest: “The reward of the one who pardons is upon Allah.” (42:40)
