КОРАН (английский перевод) - 3.20

If they argue with you, say: 'I have submitted my face to Allah and so have those who follow me. ' To those who have received the Book (Jews and Nazarenes) and to the ignorant, ask: 'Have you submitted yourselves to Allah? ' If they became Muslims they were guided, if they turn away, then your only duty is to warn them. Allah is watching over all His worshipers.
