5:5Today all good things are made lawful for you. And the food of those given the Scripture is lawful for you, and your food is lawful for them. So are chaste believing women, and chaste women from the people who were given the Scripture before you, provided you give them their dowries, and take them in marriage, not in adultery, nor as mistresses. But whoever rejects faith, his work will be in vain, and in the Hereafter he will be among the losers.

5:33The punishment for those who fight God and His Messenger, and strive to spread corruption on earth, is that they be killed, or crucified, or have their hands and feet cut off on opposite sides, or be banished from the land. That is to disgrace them in this life; and in the Hereafter they will have a terrible punishment.

5:41O Messenger! Do not let those who are quick to disbelief grieve you—from among those who say with their mouths, “We believe,” but their hearts do not believe; and from among the Jews—listeners to lies, listeners to other people who did not come to you. They distort words from their places, and they say, “If you are given this, accept it; but if you are not given it, beware.” Whomever God has willed to divert, you have nothing for him from God. Those are they whose hearts God does not intend to purify. For them is disgrace in this world, and for them is a great punishment in the Hereafter.

5:115God said, “I will send it down to you. But whoever among you disbelieves thereafter, I will punish him with a punishment the like of which I never punish any other being.”
