Many researchers agree that the level of religious personality influences an individual attitude. In Islam, nurturing a good religious personality can be done through Islamic Sufism practices. Therefore, this study has identified the relationship between Islamic Sufism practices and the religious personality among Muslim students in the university. It used a survey design that covered three scales of religious personality. A total of 296 questionnaires were collected in four universities in Malaysia. It was found that Islamic Sufism practices have a significant positive correlation with student's religious personalities. These results provide new insight into Sufism practices and religious personality among university students.
