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.

5:89God does not hold you accountable for your unintended oaths, but He holds you accountable for your binding oaths. The atonement for it is by feeding ten needy people from the average of what you feed your families, or by clothing them, or by freeing a slave. Anyone who lacks the means shall fast for three days. That is the atonement for breaking your oaths when you have sworn them. So keep your oaths. Thus God makes clear His Revelations to you, that you may be grateful.
