O you who believe! Take not My enemy and your enemy for friends: would you offer them love (or friendship) while they deny what has come to you of the truth, driving out the Messenger and yourselves because you believe in Allah, your Lord? If you go forth striving in My path and seeking My pleasure, would you manifest love to them? And I know what you conceal and what you manifest; and whoever of you does this, he indeed has gone astray from the Straight Way.
