5:27And relate to them the true story of Adam's two sons: when they offered an offering, and it was accepted from one of them, but it was not accepted from the other. He Said, “I will kill you.” He Said, “God accepts only from the righteous.”

5:36As for those who disbelieve, even if they owned everything on earth, and the like of it with it, and they offered it to ransom themselves from the torment of the Day of Resurrection, it will not be accepted from them. For them is a painful punishment.

5:39But whoever repents after his crime, and reforms, God will accept his repentance. God is Forgiving and Merciful.

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.
