Is it permissible to offer condolences to non-Muslim employees?

Question : What do you say in our time? Do we offer condolences to non-Muslims, and to the non-Muslims who are present? By Allah. To begin with. Yes.

Answer : It may be said that they are not offered condolences because doing so is a form of honoring them, except for what has become customary between nations where it is unavoidable; in that case, there is no harm in it, if Allah wills.
