Abstract: Sustainable development has become a central priority for Islamic countries as
they navigate demographic pressures, climate risks, structural economic challenges, and the
demands of global integration. This article examines the key determinants, constraints, and
opportunities shaping sustainable development across the member states of the Organization of
Islamic Cooperation (OIC). Using contemporary literature, international datasets, and
comparative evidence, the study analyzes the multidimensional nature of sustainability—economic
diversification, social inclusion, environmental resilience, and institutional quality—within the
framework of Islamic ethical principles. Special attention is given to the role of governance,
human capital, green finance, and technological modernization in accelerating long -term
development. The research also highlights how Islamic economic instruments, including zakat,
waqf, and sukuk, contribute to inclusive growth and environmental sustainability by promoting
equity, shared responsibility, and risk -based resource allocation. Empirical evidence indicates
that countries that effectively integrate Islamic values with modern policy tools tend to exhibit
stronger resilience, higher social cohesion, and more balanced development outcomes. The
findings underscore the importance of strengthening institutional capacities, enhancing climateadaptation strategies, and expanding sustainable finance mechanisms to support long -term
prosperity in Islamic countries.
