If they profess to be Christians they are unlikely to profess to be of the Muslim faith and vice versa.
Falsehoods told to prevent the denigration of Islam, to protect oneself, or to promote the cause of Islam are sanctioned in the Qur'an and Sunna, including lying under oath in testimony before a court, deceiving by making distorted statements to the media such as the claim that Islam is a “religion of peace”. A Muslim is even permitted to deny or denounce his faith if, in so doing, he protects or furthers the interests of Islam, so long as he remains faithful to Islam in his heart.
