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.

5:54O you who believe! Whoever of you goes back on his religion—God will bring a people whom He loves and who love Him, kind towards the believers, stern with the disbelievers. They strive in the way of God, and do not fear the blame of the critic. That is the grace of God; He bestows it upon whomever He wills. God is Embracing and Knowing.
