5:45And We wrote for them in it: a life for a life, an eye for an eye, a nose for a nose, an ear for an ear, a tooth for a tooth, and an equal wound for a wound; but whoever forgoes it in charity, it will serve as atonement for him. Those who do not rule according to what God revealed are the evildoers.

5:54O you who believe! Whoever of you goes back on his religion—God will bring a people whom He loves and who love Him, kind towards the believers, stern with the disbelievers. They strive in the way of God, and do not fear the blame of the critic. That is the grace of God; He bestows it upon whomever He wills. God is Embracing and Knowing.
