Sheikh Tantawy also reasserted that his is the best faith to follow and that Muslims have the duty of active da'wa. He has made declarations about Muslims interacting with non-Muslims who are not a threat to Muslims. There are non-Muslims living apart from Muslims and who are not enemies of Islam ("Muslims are allowed to undertake exchanges of interests with these non-Muslims so long as these ties do not tarnish the image of the faith"), and there are "the non-Muslims who live in the same country as the Muslims in cooperation and on friendly terms, and are not enemies of the faith" ("in this case, their rights and responsibilities are the same as the Muslims so long as they do not become enemies of Islam").
