[edit] Do Not Befriend Kafir
O you who believe!
do not take for intimate friends from among others than your own people; they do not fall short of inflicting loss upon you; they love what distresses you; vehement hatred has already appeared from out of their mouths, and what their breasts conceal is greater still; indeed, We have made the communications clear to you, if you will understand.
O ye who believe!
Take not for friends unbelievers rather than believers: Do ye wish to offer Allah an open proof against yourselves?
O ye who believe!
take not the Jews and the Christians for your friends and protectors: They are but friends and protectors to each other.
And he amongst you that turns to them (for friendship) is of them. Verily Allah guideth not a people unjust.
O Ye who believe! Choose not for guardians such of those who received the Scripture before you, and of the disbelievers, as make a jest and sport of your religion. But keep your duty to Allah if ye are true believers.
O ye who believe! Choose not your fathers nor your brethren for friends if they take pleasure in disbelief rather than faith. Whoso of you taketh them for friends, such are wrong-doers.
You shall not find a people who believe in Allah and the latter day befriending those who act in opposition to Allah and His Messenger, even though they were their (own) fathers, or their sons, or their brothers, or their kinsfolk; these are they into whose hearts He has impressed faith, and whom He has strengthened with an inspiration from Him: and He will cause them to enter gardens beneath which rivers flow, abiding therein; Allah is well-pleased with them and they are well-pleased with Him these are Allah's party: now surely the party of Allah are the successful ones.
Note that Quran 58:22 even divides families.
There is for you an excellent example (to follow) in Abraham and those with him, when they said to their people: "We are clear of you and of whatever ye worship besides Allah: we have rejected you, and there has arisen, between us and you, enmity and hatred for ever,- unless ye believe in Allah and Him alone": But not when Abraham said to his father: "I will pray for forgiveness for thee, though I have no power (to get) aught on thy behalf from Allah." (They prayed): "Our Lord! in Thee do we trust, and to Thee do we turn in repentance: to Thee is (our) Final Goal.

O ye who believe! Choose not your fathers nor your brethren for friends if they take pleasure in disbelief rather than faith. Whoso of you taketh them for friends, such are wrong-doers.
[edit] Being Friends with Non-Muslims
With regard to non-Muslims, the Muslim should disavow himself of them, and he should not feel any love in his heart towards them:
[Quotes Qur'an 60:1 & Qur'an 60:4]
But this does not mean that a Muslim cannot interact with them in a nice manner that will encourage them to enter Islam, so long as that is within the guidelines of sharee’ah, as Allaah says (interpretation of the meaning): [Quotes Qur'an 60:8]
The Muslim should strive hard to call non-Muslims to Islam through all possible permissible means, in the hope that they may benefit from that and respond, as Allaah says (interpretation of the meaning): [Quotes Qur'an 16:125 & Qur'an 41:33]
[The fatwa goes on to quote the following Islamic scriptures:...Muslim narrated in his Saheeh (2674); Qur'an 4:97-98; Abu Dawood narrated in his Sunan (2645); al-Tirmidhi narrated in his Jaami’ (1640); Ibn al-Qayyim said in Tahdheeb al-Sunan (‘Awn, 7/304); Abu Dawood (2787); al-Haakim (2/141); Imam Ahmad (4/365); and al-Nasaa’i (4177)]
These texts indicate that the basic principle is that the Muslim should not settle among the kuffaar in their countries, and that he is obliged to move from those lands to the Muslim lands. An exception is made from that if his staying there is necessary, but necessity should not be blown out of proportion. If the Muslim has to be with them (the non-Muslims) physically, he should not be with them in his heart, and he must avoid mixing with them unnecessarily...
...Something else that will help you to stop mixing with non-Muslims is to remember that these kaafirs – even though they may have good manners and some good qualities – also do a number of seriously wrong things, any one of which is sufficient to nullify any good deeds that they may do. Among these evil things is the belief of the Christians – for example – that God is one of three (trinity), as Allaah says (interpretation of the meaning): [Quotes Qur'an 5:73]
The other kaafir nations all attribute partners to Allaah, or else they do not believe in God at all.
The kuffaar in general do not believe in the Qur’aan or in the message of our Prophet Muhammad (peace and blessings of Allaah be upon him), rather they reject the Qur’aan and they reject our Prophet (peace and blessings of Allaah be upon him); so how can a Muslim be inclined towards them with their kufr and misguidance?
Even if they give you some of your rights by treating you nicely, they do not give Allaah His rights and they do not give the Qur’aan its rights and they do not give our Prophet (peace and blessings of Allaah be upon him) his rights.
The rights of Allaah and His Book and His Prophet are more important than our personal rights. Remember this, for this is one of the things that will help you to hate them and regard them as enemies until they believe in Allaah alone, as mentioned in the aayah quoted above (interpretation of the meaning):
[Quotes Qur'an 60:4]
[edit] Accept a gift for the purpose of dawah, but not because you love them.
It is permissible to accept a gift from a non-Muslim because he is a relative or neighbour, or for the purpose of softening his heart and calling him to Islam, but it is haraam if it is done as an act of friendship or love, because Allah says (interpretation of the meaning):
“O you who believe! Take not the Jews and the Christians as Awliyaa’ (friends, protectors, helpers), they are but Awliyaa’ of each other. And if any amongst you takes them (as Awliyaa’), then surely, he is one of them. Verily, Allaah guides not those people who are the Zaalimoon (polytheists and wrongdoers and unjust)” [al-Maa’idah 5:51]
