Should Ahl al-Kitab argue with you, O Muhammad, and maintain their irreverent position by adducing their unfounded reasons, then say to them: "I have vowed to resign myself to Allah’s purpose and I have conformed my will and my reason to His blessed will. So have those who fell into line with me." Say to them and to the illiterates: "Are you now satisfied with what you heard and have your doubts been satisfied? If you are, then conform to Islam". If they do, then they are on the path of righteousness, but should they turn a deaf ear and their hearts cannot hear the truth, you are only responsible for relating the message. Allah keeps a watchful eye upon His creation and upon the way people conduct themselves in life and He knows the attributes inherent in each and all.
