Another issue is the objective of Islamic banking to contribute to social obligation despite profit maximization. In this context, IBF institutions have been involved in debt financing oriented transactions such as murabahah instead of musyarakah and mudharabah, as they are more profitable. This research attempts to clarify Islamic banking's objective derived from Muslim scholars views and how it complies with sharia. Thus, it is necessary to rethink the paradigm of IBF that is in line with pure Islamic economics, whereas conventional banking has been shifting toward social banking. The methodology used is qualitative-descriptive-literature. The result is, several applied integrated models in IBFs, such as Social Islamic Bank Limited (SIBL), have offered Mudaraba Waqf Cash Deposit Account (MWCDA). Then sadaqa house is provided by Bank Islam Malaysia Berhad (BIMB), an integrated institution model in which Islamic banking can cooperate with other Islamic social finance such as waqf institutions in Indonesia. Finally, the research finding argues that Islamic banking's paradigm is to promote the ummah's maslahat by integrating commercial and social aspects into its operational and objective.
