92. And it is not befitting for a believer (Muslim) to kill a believer except by a mischance (292). If anyone kills a believer unknowingly then he has to free a Muslim slave, and pay blood money (restitution) to the family of the deceased, unless they forego (293) (their right). But if he (the deceased) was from who are hostile to you and he himself (294) is a believer, then there is only the free Muslim slave. And if he is from the people with whom you have a pact (295), then blood compensation should be paid to his family and the freeing of a believing slave (296). But, he whose hand does not reach to this (i.e. finds no means to free a believing slave) then he should fast for two consecutive months. This is repentance by Allah (297). And Allah is Ever-Knowing, All-Wise.
Surah Name : An-Nisa Surah Number : 4 Ayat Number: 92
178.0 you who believe! Prescribed upon you is legal retribution (387) for those murdered the free for the free, the slave for the slave and the female for the female (388). But, whoever is pardoned by his brother (389), then let there be a suitable payment to him (heir of the deceased) with good conduct. This is indeed a concession from your Lord and a Mercy (390). He who transgresses (391) thereafter, then for him is a painful torment.
