Purpose The purpose of this paper is to discuss the roles of Zakat, Sadaqah and Qardhul Hassan within the context of the existing literature as major Islamic financial instruments for enhancing socio-economic justice amongst Muslims haves and have-nots as these enhance financial inclusion in Nigeria. Design/methodology/approach The discussion in this paper is based on secondary sources such as the divine knowledge contained in the Qur’an, Hadiths and the existing literature, such as previously conducted empirical studies and Islamic world view (Tawhidi epistemology). Findings This paper implores Islamic societies to use Zakat, Sadaqah and Qardhul Hassan as instruments that encourages wealth redistribution that promotes efficient and effective wealth redistribution between haves and have-nots as part of the vicegerent (khaliphah) role between mortal being (human) and his immortal creator (Allah). This paper concludes by suggesting the use of these Islamic financial instruments as means to enhance socio-economic justice and financial inclusion in the Nigeria’s Muslims’ communities that are negatively affected by the high rate of financial exclusion and poverty as had been previously practiced in the Muslim world throughout the Islamic history. Research limitations/implications This paper provides critical suggestions on the ways Zakat, Sadaqah and Qardhul Hassan will contribute significantly towards assisting Nigeria in achieving its vision of reducing the financial exclusion rate that is currently put at 41.6% to 20% by the year 2020 and may foster inclusive growth and sustainable development. However, the limitation is that it is a mare conceptual study, and the future researchers may subject it to the scientific test to offer empirical evidence regarding the roles of Zakat, Sadaqah and Qardhul Hassan towards closing the gap of financial exclusion in Nigeria. Originality/value This paper contributes to the existing literature on the doctrine of the Islamic moral economy by recommending the adoption of Islamic financial instruments as tools for enhancing income redistribution and financial inclusion.

Purpose This paper aims to discuss the role of Waqf as a means of enhancing financial inclusion and socio-economic justice in Nigeria. Design/methodology/approach The methodology in this paper is that the data were elicited from secondary sources such as the Al-Qur’an, Hadiths and other empirical studies in the existing literature. The Tawhidi epistemology (Islamic world view) also has been obtained to deliver better understanding on the findings. Findings The paper implores Islamic societies to take advantages of integrating Waqf to support the financing needs of disadvantaged members of the Muslims communities, especially the Muslims, dominated northern Nigeria with a high level of financial exclusion. The Waqf funds if integrated and institutionalized will support the region by making the fewer privilege members of that community-engaged thereby economically and enhancing the financial inclusion. This will also lead to economic growth and socio-economic development of Nigeria. Practical implications The paper concludes by suggesting the establishment of Waqf funds to supports the less privileged people through Islamic Microfinance as means of enhancing socio-economic justice in Nigeria’s Muslims’ communities, which is negatively affected by the high rate of financial exclusion and poverty. This paper also provides critical suggestions on the ways the integration of Waqf funds will contribute significantly towards assisting Nigeria in achieving its vision of reducing the financial exclusion rate and may foster inclusive growth and sustainable development. Originality/value This paper is a conceptual study and, therefore, limited to the content of the existing literature. Hence, the future researchers may replicate and test it empirically for a more scientific justification regarding the roles of Waqf towards enhancing financial inclusion in Nigeria.
