Surah Mumtahina
You looking too deep into it. If you read the first verse entirely, you will understand: O you who have believed, do not take My enemies and your enemies as allies, extending to them affection while they have disbelieved in what came to you of the truth, having driven out the Prophet and yourselves [only] because you believe in Allah , your Lord. If you have come out in My cause and seeking means to My approval, [take them not as friends]. You confide to them affection, but I am most knowing of what you have concealed and what you have declared [war secrets of believers]. And whoever does it among you has certainly strayed from the soundness of the way. (60:1) If they gain dominance over you, they would be to you as enemies and extend against you their hands and their tongues with evil, and they wish you would disbelieve. (60:2) Now you must read these verses with verse 60:8-9 and realize that Allah is forbidding believers from making friends with kafir during war. But those who do not persecute the believers, there is nothing forbidden between them, so mawadah is implied. However reason the word love or affection is used in first verse is that believers should not mingling with people who persecute them, leak information to them to get on their good side, trying to show love and affection in this form. The verses should be understood in the Surah’s context.
