It is not lawful for a believer to kill another except by mistake. And whoever kills a believer unintentionally must free a believing slave and pay blood-money to the victim’s family—unless they waive it charitably. But if the victim is a believer from a hostile people, then a believing slave must be freed. And if the victim is from a people bound with you in a treaty, then blood-money must be paid to the family along with freeing a believing slave. Those who are unable, let them fast two consecutive months—as a means of repentance to Allah. And Allah is All-Knowing, All-Wise.

It is not for a believer to kill a believer except (that it be) by mistake; and whosoever kills a believer by mistake, (it is ordained that) he must set free a believing slave and a compensation (blood-money, i.e. Diya) be given to the deceased’s family unless they remit it. If the deceased belonged to a people at war with you and he was a believer, the freeing of a believing slave (is prescribed); and if he belonged to a people with whom you have a treaty of mutual alliance, compensation (blood-money - Diya) must be paid to his family, and a believing slave must be freed. And whoso finds this (the penance of freeing a slave) beyond his means, he must fast for two consecutive months in order to seek repentance from Allâh. And Allâh is Ever All-Knowing, All-Wise.
