Somewhere in Quran I found it is written that we shouldn't take non-Muslims as a friend, if we do so then we will become one of them. What is the explanation of it? The thing is we used to meet many non-Muslims in our workplace or the educational institutes and many where. And we consider them as like our friends, the line isn't clear to me. Did Allah mean all non-Muslims or just who do act as non-Muslim in the path of Allah?
