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.

5:61When they come to you, they say, “We believe,” though they have entered with disbelief, and they have departed with it. But God is well aware of what they hide.

5:68Say, “O People of the Scripture! You have no basis until you uphold the Torah, and the Gospel, and what is revealed to you from your Lord.” But what is revealed to you from your Lord will increase many of them in rebellion and disbelief, so do not be sorry for the disbelieving people.
