O you who have faith! Retribution is prescribed for you regarding the slain: freeman for freeman, slave for slave, and female for female. But if one is granted any extenuation by his brother,1 let the follow up [for the blood-money] be honourable, and let the payment to him be with kindness. That is a remission from your Lord and a mercy; and should anyone transgress after that, there shall be a painful punishment for him.
