And if they dispute with you, then say, "I have surrendered my whole self unto Allah, and so have those who follows me." And say to those who have been given the Book, and unto the unlearned (or unread or Gentiles), "Have ye, too, surrendered" and if they surrender, then are they truly guided. But if they turn their backs, then your duty is only to convey the message unto them. Allah is Seer of His servants.
