Believers, if you have left (your homes and) have come forth to struggle in My Way and to seek My good pleasure, do not make friends with My enemies and your enemies. You befriend them whereas they have spurned the Truth that has come to you; and (such is their enmity that) they expel the Messenger and yourselves for no other reason than that you believe in Allah, your Lord. You send to them messages of friendship in secrecy, although I know well whatever you do, be it secretly or publicly. And whosoever of you does so has indeed strayed far away from the Straight Path.
