Neither the word hirabah nor the triliteral root verb haraba occurs in the Quran, although the verbal noun form (i.e. hirabah) is frequently used in classical and modern books of Islamic jurisprudence.
Muslims can deal with non-Muslims in the spirit of tolerance, sympathy, goodwill, equity, justice, favour and kindness, almost every-thing within that line of conduct. In fact, they should do that for they have been taught to do that.

This is the issue known as the 'Tark al-Muwālāt' to refrain from deep (friendship) in Islamic terminology.
