The purpose of this paper is to discuss the methodology of integrated knowledge in Islamic economics and finance and seek to offer collective ijtihād as one way to find solutions to the existing problems in the field.,The study is based on the idea of multidisciplinarity or interdisciplinarity, which uses not only traditional sources of Islam and economics, such as uṣūl al-fiqh, fiqh mu’amalat, econometrics, statistics, microeconomics and macroeconomics but also looks into behavioural and natural sciences for inspiration and solutions. This paper is constructed using the methodology of “the two readings”, as promoted by the International Institute of Islamic Thought, and which combines the revealed and the existential sciences.,This paper proposes the collaborative multidisciplinary methodology as the main approach to studying the modern problems and challenges, as well as for finding solutions in the fields of Islamic economics and finance.,Studying and researching issues, particularly in the field of Islamic economics and finance, from an interdisciplinary perspective, effectively broadens practical applications and possibilities in Islamic finance.,This paper contributes to social sciences, especially the field of Islamic finance, and calls upon researchers to engage in multidisciplinary studies.

伊斯兰经济学和金融学中的综合知识的方法论：集体ijtihad

本文的目的是讨论伊斯兰经济学和金融学中的集成知识的方法，并寻求提供集体的《伊斯兰教义》作为寻找该领域现存问题解决方案的一种方法。该研究基于多学科或跨学科的思想不仅使用伊斯兰教和经济学的传统资源，例如uṣūlal-fiqh，fiqh mu'amalat，计量经济学，统计学，微观经济学和宏观经济学，而且还从行为和自然科学中寻找灵感和解决方案。本文是根据国际伊斯兰思想研究所的倡导，采用“两种解读”的方法构建的，该方法结合了揭示的科学和存在的科学。
