In what is offered, the authors have gone to study the relation between Islamic lifestyle and success in delivering the message of religion. The method followed is correlative description. The research has been carried out on 100 people of Qom seminary students.   
    For this purpose, the questionnaires of "Islamic lifestyle (ILST-75)", by Kawiyani, and "the constituents of a successful propagator in the Qur'an and traditions", by Jawanshir" have been used.  
    In their analysis of the data, the authors have made use of central index, dispersion index, and correlation coefficients in description, and of Z test for meaningfulness of Pierson's r and F test for the analysis of meaningfulness of regression in the process of inference.
 The findings of this research suggest that "there is a positive relation between the Islamic lifestyle and success in propagation". Accordingly, the more the propagator enjoys the Islamic lifestyle the more he will be successful in his propagation.
