The Ruling on Dealing with a Disbeliever in Work

Question:
The questioner says: I work with a man who is a Christian named Abdullah. Is there anything wrong with me when I call him "O Abdullah," knowing that he is an Arab? And what should I do regarding him, given that I have advised him to embrace Islam? He said, "You want to enter Paradise at my expense," and he keeps repeating this. Please advise us, may Allah grant you success?

Answer:
In any case, hating the disbeliever is obligatory, and it is not permissible to love him, , or their brothers or their kin. "Friends" means that you love them and feel affection for them in your hearts. As for working with him while you hate him—you hate him, and it is only a circle of work or a job that brings you together—the matter in this is easy: you do your work and do not love him. However, it is obligatory for companies and business owners; it is obligatory for them not to bring in disbelievers, to keep them away from the lands of the Muslims, and to bring in Muslim workers. If they bring in disbelievers and bring them in, they sin by doing so with a great sin, and they cause harm to the Muslims for which they bear the burden, and may Allah protect us from that.
