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.

5:57O you who believe! Do not befriend those who take your religion in mockery and as a sport, be they from among those who were given the Scripture before you, or the disbelievers. And obey God, if you are believers.
