Qisas or Qiṣāṣ (Arabic: قِصَاص, romanized: Qiṣāṣ, lit. 'accountability, following up after, pursuing or prosecuting') is an Islamic term interpreted to mean "retaliation in kind",[1][2] "eye for an eye", or retributive justice. Qisas and diyya are two of several forms of punishment in classical/traditional Islamic criminal jurisprudence, the others being Hudud and Ta'zir.[3] The legal systems of Afghanistan,[4] Iran, Pakistan, Saudi Arabia, the United Arab Emirates, Qatar, and the northern states of Nigeria currently apply qisas.
