Corporate waqf has contributed great significant changes into the waqf system as a whole. But, the involvement of corporate companies in corporate waqf still low. In Malaysia, corporate waqf has been led by Johor Corporation Berhad (JCorp) through their subsidiary which is Waqaf An-Nur Corporation Berhad (WANCorp). They have also opened participation to the public who wish to get involved in this corporate waqf through the introduction of corporate cash waqf instrument. This effort is fruitful. So, if more participation either from corporate companies or public, definitely this waqf fund can be expanded. Further, more fund will be channelled to Fisabilillah activities. The focus of this study is towards corporate cash waqf: What makes someone to act is attribution of intention. Without intention, something cannot be implemented. Similarly to corporate cash wad if someone has intention to contribute, then the possibility he or she will participate in corporate cash waqfis higher. SO, this study wants to investigate the factors influencing individual's intention to participate in corporate cash waqf based on the Theory of Planned Behaviour (TPB). The factors that are taken into consideration for TPB are; attitude, subjective norm and perceived behavioural control. Based on the previous study, religiosity also is one of the factors which influencing intention to act. Specifically, this study has three objectives which are; firstly, to examine the extent of attitude, subjective norm and perceived behavioural control in predicting the individual's intentiom to participate in corporate cash wad. Secondly, to investigate the best predictor for the individual's intention to participate in corporate cash waqf. Thirdly, to examine the extent of variable of TPB (attitude, subjective norm and perceived behavior control) in predicting individual's intention to participate in corporate cash waqf if the religiosity factor is controlled. This study conducted at Majfis Agama Islarn Wilayah Persekutuan (MAIWP) since if is one of the institdons that implemented this corporate waqf. In line with research objective, their employee are respondents of this study because they are more exposed towards corporate waqf instrument. The sample of this study consist 285 respondent Questionnaires were distributed through Corporate Unit of MAIWP. Multiple regression analysis was used to test the relationship between variables. The results of this study found that attitude, subjective norm and perceived behavioural control were significantly related to individual’s intention to participate in corporate cash waqf. Meanwhile, the attitude is the strongest factor in predicting dependent variable compared to other factor. However, those factors are still able to predict the dependent variable even the religiosity factor was controlled.
