Violence
If any polytheist seeks your protection, grant it to him so that he may hear the words of Allah, then escort him to a place of safety. That is because they are a people who do not know.
9:6And if anyone of the idolaters seeketh thy protection (O Muhammad), then protect him so that he may hear the Word of Allah, and afterward convey him to his place of safety. That is because they are a folk who know not.
