Can I follow Islam and still be close friends to unbelievers?
O ye who believe! Take not for friends unbelievers rather than believers: Do ye wish to offer Allah an open proof against yourselves? (4:144)
O ye who believe! Take not the Jews and the Christians for friends. They are friends one to another. He among you who taketh them for friends is (one) of them. Lo! Allah guideth not wrongdoing folk. (5:51)
The Misbeliever is a helper (of Evil), against his own Lord! (25:55)
O ye who believe! Fight those of the disbelievers who are near to you, and let them find harshness in you, and know that Allah is with those who keep their duty. (9:123)
