Say, "O population of the Book, (Or: Family of the Book, i.e., the Jews and christians) come to a level word between us and you, that we worship none except Allah, and that we do not associate anything with Him, and that some of us do not take to themselves others (Literally: some "others") as lords, apart from Allah." So, in case they turn away, then say, "Bear witness that we are Muslims." (Literally: we have surrendered "to Allah").
