The growth of the Islamic economy in Indonesia requires financing instruments that are not only in line with Islamic principles but also capable of driving the real sector productively. Istisna' contracts, which involve the sale of goods by order, offer a promising solution for financing construction projects, manufacturing, and micro-businesses. This study aims to explore the definition, role, and implementation of istisna' contracts in supporting the growth of the Islamic economy. Using a descriptive qualitative method based on literature review and normative-economic approaches, the study finds that istisna' contracts can enhance productivity, create employment opportunities, and support sustainable economic development. However, their implementation still faces challenges such as limited public understanding, financing risks, and a lack of education for business actors. Therefore, efforts to optimize the use of istisna' in Islamic financial institutions are essential

Musyarakah Mutanaqisah (MMQ) is a form of sharia-based financing that offers a home ownership solution free from elements of interest (riba). This article aims to analyze the application of the MMQ contract in housing finance, compare it with the conventional mortgage scheme (Kredit Pemilikan Rumah/KPR), and evaluate its impact on community welfare. This study employs a descriptive qualitative approach through literature review of academic sources, regulations, and other relevant data. The analysis shows that MMQ is superior in terms of compliance with Islamic principles, fairness in risk sharing, and flexibility in payment structure. Furthermore, the MMQ scheme contributes to the improvement of social and economic well-being, particularly for the lower-middleincome segment of society. Nevertheless, its implementation still faces challenges such as the risk of default and the need for strengthened risk management systems. Therefore, collaboration between Islamic financial j, the government, and the public is essential to optimize the potential of MMQ as a fair and sustainable alternative for home financing
