In this study, one of the methodologies of the contemporary Christian missionaries with regard to belief in Allah is taken into account. In this contex, the attempt of Christians to justify trinity with reference to Holy Kur'an is discussed, and a response is provided to their claims with regard the concept of oneness of Allah, and theoretical understanding of Him. As a consequence, it is emphasized that the relevant arguments are devoid of a rational and scientific foundation and that they are far from being impartial.
