2:120: “Never will the Jews nor the Christians be pleased with you till you follow their religion. Say: "Verily, Islâmic Guidance is the only Guidance. And if you were to follow their desires after what you have received of Knowledge, then you would have against Allâh neither any protector nor helper.”
3:56: “As to those who disbelieve, I will punish them with a severe torment in this world and in the Hereafter, and they will have no helpers."
3:85: “And whoever seeks a religion other than Islâm, it will never be accepted of him, and in the Hereafter he will be one of the losers.”
3:118: “O you who believe! Take not as your helpers or friends those outside your religion since they will not fail to do their best to corrupt you. They desire to harm you severely. Hatred has already appeared from their mouths, but what their breasts conceal is far worse. Indeed We have made plain to you the verses if you understand.”
3:178: “And let not the disbelievers think that Our postponing of their punishment is good for them. We postpone the punishment only so that they may increase in sinfulness. And for them is a disgracing torment.”
5:14: “And from those who call themselves Christians, We took their covenant, but they have abandoned a good part of the Message that was sent to them. So We planted amongst them enmity and hatred till the Day of Resurrection, and Allâh will inform them of what they used to do.”
5:51: “O you who believe! Take not the Jews and the Christians as friends, they are but friends to one another. And if any amongst you takes them as friends, then surely he is one of them. Verily, Allâh guides not those people who are the wrong*doers.”
5:73: “Surely, disbelievers are those who said: "Allâh is the third of the three (in a Trinity)." But there is no god but Allâh. And if they cease not from what they say, verily, a painful torment will befall the disbelievers among them.”
8:39: “And fight them until there is no more disbelief in Islam and the religion will all be for Allâh Alone...”
9:23: “O you who believe! Take not for supporters your fathers and your brothers if they prefer disbelief to Belief. And whoever of you does so, then he is one of the wrong-doers.”
9:29: “Fight against those who (1) believe not in Allâh, (2) nor in the Last Day, (3) nor forbid that which has been forbidden by Allâh and His Messenger (4) and those who acknowledge not Islam as the religion of truth among the people of the Scripture, until they pay the Jizyah [religious tax] with willing submission, and feel themselves subdued.”
9:34: “O you who believe! Verily, there are many of the Jewish rabbis and the Christian monks who devour the wealth of mankind in falsehood, and hinder men from the Way of Allâh. And those who hoard up gold and silver, and spend it not in the Way of Allâh -- announce unto them a painful torment.”
9:123: “O you who believe! Fight those of the disbelievers who are close to you, and let them find harshness in you, and know that Allâh is with those who are the pious.”
