Using an inductive approach to review concepts and global practices, and an analytical method to assess performance, the paper addresses four main themes: the concept of investment funds, conventional and Islamic investment funds, the current state of sustainable integration in Islamic funds, and the key development requirements. The findings indicate a strong alignment between Islamic ethical values and global sustainability standards, particularly in terms of justice, transparency, and environmental responsibility. Saudi Arabia and Malaysia were highlighted as leading models in promoting sustainable Islamic investment. The study recommends the development of Shariah-based sustainability indices, increasing green sukuk issuance, and enhancing regulatory frameworks to support sustainable investment ecosystems.ArIslamic FinanceInvestment fundSustainable InvestmentGreen SukukMaqasid al-Shariahjournal-article289317311
