60:1
O you who believe! (Do) not take My enemies and your enemies (as) allies offering them love while they have disbelieved in what came to you of the truth, driving out the Messenger and yourselves because you believe in Allah, your Lord. If you come forth (to) strive in My way and (to) seek My Pleasure. You confide to them love, but I Am most knowing of what you conceal and what you declare. And whoever does it among you then certainly he has strayed (from the) straight path.
