So if they disagree with you, say: "I have submitted my whole self to Allah, and so have those who follow me." And say to the People of the Book and to those who have not yet learned: "Do you (also) submit yourselves?" If they do, they are in right guidance, but if they turn away, your duty (O Prophet) is to convey the Message; And Allah is All Seeing (Baseer), for all His servants.
