5:7And Remember God’s blessings upon you, and His covenant which He covenanted with you; when you said, “We hear and we obey.” And remain conscious of God, for God knows what the hearts contain.

5:13Because of their breaking their pledge, We cursed them, and made their hearts hard. They twist the words out of their context, and they disregarded some of what they were reminded of. You will always witness deceit from them, except for a few of them. But pardon them, and overlook. God loves the doers of good.

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.

5:52You will see those in whose hearts is sickness racing towards them. They say, “We fear the wheel of fate may turn against us.” But perhaps God will bring about victory, or some event of His making; thereupon they will regret what they concealed within themselves.

5:113They said, “We wish to eat from it, so that our hearts may be reassured, and know that you have told us the truth, and be among those who witness it.”
