This article explores the theoretical framework underpinning the development of an Islamic competency instrument for nursing educators in Malaysian higher education institutions. The framework integrates multiple Islamic and educational theories, including Ibn Khaldun’s Model of Islamic Education, the Theory of Caring in Islam, the Concept of Islamic Work Ethics, and the Iceberg Model of Competency. Additionally, the Design and Development Research (DDR) model serves as the methodological foundation for instrument development. Based on the theories and models discussed, the researcher has integrated all relevant frameworks to develop an Islamic competency instrument for nursing educators in higher education institutions in Malaysia. The framework provides a structured basis for ensuring nursing educators embody both spiritual and professional competencies consistent with Islamic principles.
