The purpose of this paper is to propose the use of Islamic moral transaction mode as a moderator in sustainable Islamic microfinance banks (IMFBs) business model.
The paper highlighted the major issues of microfinance banks in Nigeria and presented an integrated model that will suffice the long-term survival of the institution. Moreover, regression analysis is also employed to examine the impacts of financial outreach on the Nigerian economic growth.
The authors find that Islamic moral transaction mode will moderate the sustainable Islamic banking business which can influence the sustenance of IMFBs and the well-being of the society through financial outreach.
The paper has empirically tested the impact of financial outreach on growth, and suggested future studies to investigate the existing relationships among the proposed model components. Therefore, further studies have the opportunity to develop measurements that will guide in testing the model, as well as strengthening its components.
Implementing this model will enhance the sustainability of IMFBs and socio-economic well-being of the society through financial outreach. Consequently, this study also suggests other policy measures that will improve the sustenance of IMFBs and the society as a whole.
The paper contributes to the existing literature of microfinance banks by linking the components of the sustainable business model to primary evidence of Sharia coupled with an in-depth link to generosity.
