The Ruling on Dealing with Disbelievers and Showing Them Affection

Question:
The third question: How should our relationship with disbelievers be?

Answer:
Is it a worldly relationship involving buying and selling? And regarding neighbors, the rulings of neighborly relations, and being kind to neighbors, this is what Islam commands. What Islam commands or what Islam permits: Islam permits buying and selling with disbelievers in permissible matters. It is permissible to give them gifts and to accept gifts from them. If they are neighbors, they have the right of neighborly relations. This is permissible in Islam; in fact, some of it is permissible (mubah) and some of it is recommended (mustahabb).
As for the relationship of love and friendship, it is not permissible. Do not love them, but rather hate them and be hostile to them for the sake of Allah the Exalted, but without aggression toward them. Do not love them in your hearts, but do not aggress against them or wrong them.
