Abstract
Mua’llaf is a person chosen by Allah SWT who is guided to return to the religious nature of Islam. When a
mua’llaf does not get the guidance of true Islamic knowledge, it will cause confusion and
misunderstanding of religion in life. Through the organisation of da’wah activities, Non-Governmental
Organisations (NGOs) have the role of providing Islamic guidance to mua’llaf in Malaysia. The objective
of this study is to analyse the effect of da’wah activities of non-Governmental Organisation (NGO) on the
religious understanding of mua’llaf in Malaysia. This is quantitative study methodology with study design
research. A total of 250 study respondents (SR) comprised of mu’allaf were selected at plain random. The
distributions of the questionnaire were carried out in the East Coast Zone, Southern Zone of Peninsular
Malaysia, Northern Zone of Peninsular Malaysia, Central Zone of Peninsular Malaysia and East Malaysia
Zone. Data from the questionnaires were analysed by descriptive statistics in the form of percentages,
mean scores and standard deviations using Statistical Package for Social Science (SPSS) 22. The research
instrument used is reliable because it achieves the value of the coefficient Alpha Cronbach 0.91 at a very
high level. The results showed that the mean value was between 1.53 to 1.83, the standard deviation was
between 0.625 to 0.749 and the interpretation was at a low level. The correlation was significant with a
confidence value of r = 0.759 ** at the level of <0.01. The results of the study analysis show that there is a
high positive relationship between the understandings of the religion of Islam for mua’llaf with da’wah
activities of NGOs. Moreover, this study has important implications for the development of knowledge,
mu’allaf, Islamic organisations, government and private institutions and communities in society
