Purpose: This paper explores the experiences and strategies that have emerged from an Islamic university in Brunei Darussalam in its efforts to adapt to the new normal. It aims to provide a comprehensive post COVID-19 teaching and learning strategies framework and understand how the principles of Islam can be harmonised with modern practices, offering valuable lessons for educational institutions worldwide. Design/methodology/approach: The study employed a three-fold methodology. Initially, the authors conducted a comprehensive review of the post-COVID-19 experiences within Islamic universities. Subsequently, they administered a structured questionnaire to academic staff and students at an Islamic university in Brunei, utilising Google survey forms. Based on the insights from the data analysis, strategies were carefully formulated. Ultimately, this informed the development of a framework grounded in the established strategies. Findings: The significant findings from this study include the adoption of "e-Talaqqi" and how this can be related to Maqasid Shariah to produce a conceptual framework of post-COVID-19 strategies adaptable for Islamic Higher Education Institutions (HEIs) and how that can be related to Maqasid Shariah in line with the values of Islamic-based universities. Research limitations/implications: The applicability of the framework developed from data gathered at an Islamic university in Brunei might have certain limitations when extended to other Islamic HEIs. Future research should aim to cover more Islamic HEIs across various countries, thereby strengthening a broader applicability of the framework. Moreover, it is advisable that the developed framework undergoes statistical validation to fortify it. Practical implications: The study's implications encompass theory, researchers, educators, policymakers, and all stakeholders concerned with the past, present, and future of HEIs, particularly in facilitating the adaptation of post-COVID-19 norms within Islamic HEIs. Social implications This paper holds the potential to significantly benefit society by providing invaluable insights to educators and various sectors, aiding them in enhancing their learning pedagogies. Originality/value: This study has developed a conceptual framework that offers strategies tailored for Islamic HEIs in the post-COVID-19 era, harmonising with the principles of Islamic-based universities, in alignment with Maqasid Shariah. Consequently, this research serves as a significant contribution to the evolution of new theoretical paradigms because of COVID-19.
