Quran 3:119 — The Amramites (Ali-'Imran)

Here you are loving them, while they do not love you, and you believe in all the scripture. When they meet you they say, "We believe," but as soon as they leave, they bite their fingers out of rage towards you. Say, "Die in your rage." GOD is fully aware of the innermost thoughts.

[3:118] O you who believe, do not befriend outsiders who never cease to wish you harm; they even wish to see you suffer. Hatred flows out of their mouths and what they hide in their chests is far worse. We thus clarify the revelations for you, if you understand.

[3:120] When anything good comes your way they hurt, and when something bad happens to you they rejoice. If you steadfastly persevere, and maintain righteousness, their schemes will never hurt you. GOD is fully aware of everything they do.
