The Women - 4:92 A believer shall not kill a believer except by accident. Whoever kills a believer by accident must release a believing slave and pay a diet to the family of the deceased. Unless they give up the diet and accept it as charity. If it is a believer from a community that is at war with you, then you must release a believing slave. But if the deceased belongs to a community with whom you have an agreement, then you must give his family a diet and release a believing slave. Whoever cannot find the money or a slave to release should fast for two months in a row so that Allah may accept his repentance. Allah is All-Knowing, All-Wise.
The believers do not kill a soul unjustly which Allah has forbidden:

Then whoever transgresses after that, for him is a painful torment.

Nevertheless, most of them immediately began to commit transgression in the earth.
The Table Spread/5:45 There We commanded them: We commanded them: Life for life, eye for eye, nose for nose, ear for ear, tooth for tooth and wounds for wounds. Whoever gives up this right, He will cover his sins. Those who do not judge by what Allah has revealed are wrongdoers.
