O ye who believe! Take not into your intimacy those outside your ranks: They will not fail to corrupt you. They only desire your ruin: Rank hatred has already appeared from their mouths: What their hearts conceal is far worse. We have made plain to you the Signs, if ye have wisdom. (3:118)

Ah! ye are those who love them, but they love you not,- though ye believe in the whole of the Book. When they meet you, they say, "We believe": But when they are alone, they bite off the very tips of their fingers at you in their rage. Say: "Perish in you rage; God knoweth well all the secrets of the heart." (3:119)

If aught that is good befalls you, it grieves them; but if some misfortune overtakes you, they rejoice at it. But if ye are constant and do right, not the least harm will their cunning do to you; for God Compasseth round about all that they do. (3:120)

O ye who believe! if any from among you turn back from his Faith, soon will God produce a people whom He will love as they will love Him,- lowly with the believers, mighty against the rejecters, fighting in the way of God, and never afraid of the reproaches of such as find fault. That is the grace of God, which He will bestow on whom He pleaseth. And God encompasseth all, and He knoweth all things. (5:57)

Therefore expound openly what thou art commanded, and turn away from those who join false gods with God. (15:94)

Turnest thou not thy attention to those who turn (in friendship) to such as have the Wrath of God upon them? They are neither of you nor of them, and they swear to falsehood knowingly. (58:14)

O ye who believe! Take not my enemies and yours as friends (or protectors),- offering them (your) love, even though they have rejected the Truth that has come to you, and have (on the contrary) driven out the Prophet and yourselves (from your homes), (simply) because ye believe in God your Lord! If ye have come out to strive in My Way and to seek My Good Pleasure, (take them not as friends), holding secret converse of love (and friendship) with them: for I know full well all that ye conceal and all that ye reveal. And any of you that does this has strayed from the Straight Path. (60:1)

O ye who believe! Turn not (for friendship) to people on whom is the Wrath of God, of the Hereafter they are already in despair, just as the Unbelievers are in despair about those (buried) in graves. (60:13)
