The students of Indonesia University of Education (UPI) and Bandung Islamic University (UNISBA) typically practice religion as it was received from their parents and socio-religious environment. They "Salat," which is the main prayer of Islam, simply abort their obligations, and after praying, immediately leave their prayer mats without making "dhikr" or remembering God first. Furthermore, they do not understand "khushu' Salat," which involves remembering God throughout the prayer, along with the meaning of "dhikr," and the importance of a "Murshid," which is the Grand Shaykh of Sufi Order. They also view Sufism as non-Islamic teaching and are cynical about the practitioners. Therefore, this study aims to examine the effectiveness of the Sufistic learning model in Islamic Religious Education to improve students' understanding of these teachings in a substantive and tolerant manner. This research used an R&D approach, and the stage that was performed involved the preparation of a draft model and associated trials. Meanwhile, the learning used the "madhhab" typology approach of the Sufi and "Shari'a" Islamic models. The trial results showed that the Sufistic approach was effective in increasing students' understanding of Islamic teachings in a substantive and tolerant manner. Before learning, students were unaware of Sufi Islam and viewed it as a foreign influence. Also, they did not understand "khushu'" prayers, comprehend the importance of "dhikr," nor that of learning from "Murshid." After learning, they understood Sufism, accepted the teachings and did not consider them to be foreign influences, and also recognized Islam in a substantive and tolerant manner. Therefore, the Sufism approach is improving the quality of religion and tolerance of students, with the implication that the model is an alternative in learning Islamic education at universities.
