﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّخِذُوا۟ ٱلْكَٰفِرِينَ أَوْلِيَآءَ مِن دُونِ ٱلْمُؤْمِنِينَ ۚ أَتُرِيدُونَ أَن تَجْعَلُوا۟ لِلَّهِ عَلَيْكُمْ سُلْطَٰنًۭا مُّبِينًا ﴾

“O you who have attained to faith! Do not take the deniers of the truth for your allies in preference to the believers! Do you want to place before God a manifest proof of your guilt?”

[O you who believe] take not the disbelievers as friends, lest their disbelief and their veiledness infect them through [their] companionship and mixing with them. For there nothing influences more than companionship. Moreover, the tendency towards friendship of them cannot [ultimately] be free of a generic compatibility between [the disbelievers and] them, as there must exist with them [these believers] some latent caprice and a voracity for a vile habit that subsumes [both of] them. One cannot be assured that they will not fall into disbelief [by such friendship] as a result of the overpowering of caprice and the soul; [do you desire to give God over you] a clear warrantḍ, a manifest argument in favour of requiting you, as a result of the taking root [in you] of that configuration through which you incline to friendship of them by being their companions and mixing socially with themḍ
