Previous research has emphasized the importance of promoting female entrepreneurship in developing countries. Women often lack assets, financial history and are disadvantaged in acquiring wage-employment. In Tanzania, female entrepreneurs face these constraints when seeking resources for entrepreneurial purposes. Provision of microcredits has thereby been highlighted to empower women. Impact assessments of women accessing microcredits has its focus on evaluating a change in the decision-making of women. Our study focusses on combining factors affecting female entrepreneurship and achievements. Scarce literature has covered the possible empowerment of Muslim female entrepreneurs caused by microcredits in the world and in the context of Tanzania. Many Muslims do not engage in interest-based transactions. Instead, they use the products of Islamic microfinance institutions, who refrain from using interest-based credits. Our study, therefore, aims to explore the possible empowerment of Muslim female entrepreneurs, comparing female entrepreneurs who use microcredits provided by conventional microfinance institutions (MFIs) and Islamic microfinance institutions (IMFIs). Our study points out in line with previous research that microcredits empower Muslim female entrepreneurs in Tanzania. The study highlights that Muslim female entrepreneurs in Tanzania prefer non-interest-based microcredits over interest-based microcredits, as they are in accordance with their faith.
