5:32Because of that We ordained for the Children of Israel: that whoever kills a person—unless it is for murder or corruption on earth—it is as if he killed the whole of mankind; and whoever saves it, it is as if he saved the whole of mankind. Our messengers came to them with clarifications, but even after that, many of them continue to commit excesses in the land.

5:95O you who believe! do not kill game while you are in pilgrim sanctity. Whoever of you kills any intentionally, its penalty shall be a domestic animal comparable to what he killed, as determined by two honest persons among you—an offering delivered to the Kaabah. Or he may atone by feeding the needy, or its equivalent in fasting, so that he may taste the consequences of his conduct. God forgives what is past. But whoever repeats, God will take revenge on him. God is Almighty, Avenger.
