Believers, retribution is prescribed for you in cases of murder: the free man for the free man, the slave for the slave, the female for the female. If the offender is granted some remission by the heir of the slain person, the agreed penalty should be equitably exacted and should be discharged in a handsome manner. This is an alleviation from your Lord and an act of grace. He who transgresses after this shall have a painful punishment.
