Qisas or Qiṣāṣ (Arabic: قِصَاص, romanized: Qiṣāṣ, lit. 'accountability, following up after, pursuing or prosecuting') is a term interpreted to mean "retaliation in kind", "eye for an eye", or retributive justice. In traditional Islamic law (sharia), the doctrine of qisas allows a punishment analogous to the crime. Qisas is available to the victim or victim's heirs against a person convicted of murder or intentional bodily injury. In the case of murder, qisas gives the right to take the life of the killer, if the latter is convicted and the court approves. Those who are entitled to qisas have the option of receiving monetary compensation (diyya) or granting pardon to the person instead.
